B.   FIRE ALARM CONTROL PANEL

   a.  All addressable fire alarm control systems (Cerberus/Pyrotronics MXL , Cerberus/Pyrotronics MXLV (voice alarm) and Cerberus/Pyrotronics MXL-IQ) shall have a panel mounted printer (Cerberus/Pyrotronics TSP-40, thermal strip printer). This printer shall be on the main fire alarm control panel.

   b.  All addressable fire alarm control systems (Cerberus/Pyrotronics MXL , Cerberus/Pyrotronics MXLV (voice alarm) and Cerberus/Pyrotronics MXL-IQ) shall include in the main fire alarm control panel a 80 character alphanumeric display and the required key-pad switches for full control of the fire alarm system (Cerberus/Pyrotronics MXL based "MKB"). These controls will constitute the sole source of control for the fire department.

   c.   All addressable fire alarm control systems (Cerberus/Pyrotronics MXL, Cerberus/Pyrotronics MXLV (voice alarm) and Cerberus/Pyrotronics MXL-IQ) shall replace any existing fire alarm control panels and any existing fire alarm sub-panel. The functions of these panels will be included in the design of the new addressable alarm system.

   d.   The use of any add-on or stand alone controls or control panels is not acceptable. This precludes the use of alarm power adder and extended circuit units (Pyrotronics PAD-2 for example), sub-panels for Halon control, elevator recall controls, and area specific control panels. If the alarm system must use additional remote mounted controls they shall be in the form of integrated remote panel (MXLR and MXLRV as an example). The use of an auxiliary power supply panel will be allowed if that panel is designed as part of the Cerberus/Pyrotronics MXL configuration (sample; the use of a Cerberus/Pyrotronics PS-35 configuration, or the use of amplifier and power panels in a Cerberus/Pyrotronics MXLV voice system).

   e.   The 80 character alphanumeric display shall be mounted at 5'6" to center above the floor.

   f.   All addressable fire alarm control systems (Cerberus/Pyrotronics MXL, Cerberus/Pyrotronics MXLV (voice alarm) and Cerberus/Pyrotronics MXL-IQ) shall be software configured for self restoring trouble conditions.

   g.   All addressable fire alarm control systems (Cerberus/Pyrotronics MX , Cerberus/Pyrotronics MXLV (voice alarm) and Cerberus/Pyrotronics MXL-IQ) shall be software configured for "disarm to survive reset". This applies to disarms done via the control menu and via the custom programmable function switches.

2.   In small buildings, a hard-wired conventional system may be substituted, using a Cerberus/Pyrotronics System 3, Cerberus/Pyrotronics SXL or Cerberus/Pyrotronics PXL control panel. Approval for this substitution must be obtained in advance from Capital Projects (CP). These systems shall be referred to as conventional systems.

 3.   The Campus standard for fire alarm equipment is Cerberus/Pyrotronics brand. This is a proprietary item. No equal will be accepted.

 4.   All door and other front-covers on the fire alarm control panels shall swing on factory-installed hinges. Front-covers which need to be lifted off and removed from the panel to gain access to the wiring terminals shall not be allowed. All control panels shall be supplied with complete dead-fronts so that personnel operating the switches are not exposed to the wiring or electronics.

5.   The master fire alarm control panel shall be located indoors, immediately adjacent to the main fire alarm control panel. This fire alarm control panel and master box shall be located at the Berkeley Fire Departments point for primary response. This location is to be determined by the Authority Having Jurisdiction (Campus Fire Marshal). The master or main fire alarm control panel shall contain all the fireman controls necessary for full alarm annunciation, acknowledge, silence, and reset.

C.   FIRE ALARM SUB-PANELS

When fire alarm sub-panels are needed, they shall be located immediately adjacent to the main fire alarm control panel. When remote panels are required (Cerberus/Pyrotronics MXLR, MXLRV, and auxiliary power and amplifier panels) they shall be mounted in locations that are accessible to routine maintenance, and protected from environmental hazards. Remote panels and fire alarm control panels mounted in custodial spaces, storage closets, above ceiling and damp or dusty locations shall not be allowed.

D.   MANUAL PULL STATIONS

 2.   For new hard-wired conventional installations, manual pull stations shall be Cerberus/Pyrotronics MS-57 or the equivalent.

 3.   For additions to existing installations, manual pull stations shall be of the same brand and model as existing ones, if available.

 4.   When manual pull stations are surface-mounted (as opposed to flush, or semi-flush mounted), proper back-boxes specifically manufactured for the device shall be used. Ordinary electrical junction boxes shall not be acceptable as back-boxes.

 5.   All manual pull stations shall be mounted at a height of 48" on center above finished floor.

E.   AUTOMATIC FIRE DETECTORS

 1.   Smoke detectors for the initiation of addressable building-wide alarms shall be: Cerberus/Pyrotronics FP-11(environment compensations type), Cerberus/Pyrotronics ILI-1, (ionization type), and Cerberus/Pyrotronics ILP-2 (photo-electric type). The type of smoke detector shall be determined by the individual application, including but not limited to consideration of dust, gas, air velocity, fumes and ambient electromagnetic fields.

 2.   Smoke Detectors for the initiation of conventional building-wide alarms shall be: Cerberus/Pyrotronics PE-11, Cerberus/Pyrotronics DI-3;(ionization type), or Cerberus/Pyrotronics (photo-electric type). The type of smoke detector shall be determined by the individual application, including but not limited to consideration of dust, gas, and air velocity, fumes and ambient electromagnetic fields.

Internal battery shall be omitted is the detector power is backed up by an approved emergency power system.

 4.   Shunt-trip smoke detectors, which transmit an alarm via a normally closed contact (open on alarm) shall not be permitted.

 5.   Smoke Detector Operating Voltage (conventional alarm systems):

 a.   Smoke detectors which activate the building fire alarm systems shall be powered by the power supply of the fire alarm control panel and be designed to the operating voltage of the fire alarm system (usually 22 to 28 volts DC). They shall receive their operating power on same pair of wires which is used for signaling the control panel. These are commonly called zone-powered smoke detectors.

 b.   Smoke detectors which do not activate the building fire alarm system (e.g., dormitory room smoke detectors with integral horn) shall be 120 volt devices. Power to these detectors shall be controlled by a dedicated circuit breaker in the same branch circuit panel as the building fire alarm system. These detectors shall be supervised for power loss and placement supervised by the building fire alarm system.

 6. For high-value applications and for high-air-flow applications, air-sampling-type smoke detectors are preferable to spot-type smoke detectors. Brand and model shall be submitted to Capital Projects (CP) for approval.

 7.   For high-ceiling applications and for atriums, photoelectric beam-type smoke detectors are preferred to spot-type smoke detectors. Submit brand and model to Capital Projects (CP) for approval.

 8.   For high-ceiling applications the possibility of smoke stratification shall be considered in the design of the smoke detection system.

 9.   The use of air-duct smoke detectors is discouraged. Air-duct smoke detectors shall be used only when required by the Fire Marshal for the control of heating, ventilating, damper control and air conditionings equipment. If an alternative technique for controlling the heating, ventilating, damper control and air conditioning equipment is available (e.g., 100% coverage of the affected area by spot-type smoke detectors), the alternative technique is preferred.

 10.   Air-duct smoke detectors, when used, shall trip the building fire alarm system in addition to controlling the heating, ventilating, damper control and air conditioning equipment. These duct detectors shall be either Cerberus/Pyrotronics addressable or Cerberus/Pyrotronics conventional system duct detectors equipped with relays for auxiliary control contacts. Air-duct smoke detectors shall not be used as a substitute for other types of automatic fire detection. Air-duct smoke detectors shall not serve as the sole method of automatic fire detection.

 11.   Plenum-type high air velocity smoke detectors shall be used in plenum spaces whenever possible, instead of duct smoke detectors using an extended air sampling tube.

 12.   Spot-type smoke detectors shall be placed no closer than three feet to air-supply or air-return registers.

 13.   Rate-of-rise-type thermal detectors, detectors which utilize air passing through an orifice for their operation, shall not be used in areas where high humidity is anticipated.

 14.   Heat detectors shall not be used in areas protected by a wet fire sprinkler system unless called for by the Authority having Jurisdiction (Campus Fire Marshal).

 15.   Smoke or heat detectors shall not be placed in locations that are not readily accessible for routine maintenance and testing.

 16.   Smoke and fire damper controls will activated by smoke detectors placed within 5 feet of the damper control unit.

 F.   SPRINKLER FLOW SWITCHES

 1.   Sprinkler flow switches shall be equipped with an integral time delay device which provides a delay of at least 25 seconds but no more than 40 seconds from the beginning of water flow to the initiation of the alarm signal.

 2.   All sprinkler flow switches shall be capable of a routine water flow test using an inspectorís test valve. Inspector's test valves shall be provided wherever necessary to accomplish this, preferably as far downstream from the flow switch as possible.

 3.   Each wet sprinkler system shall have a main flow switch. Sectional flow switches are encouraged.

 4.   A non-silenceable water flow alarm is not permitted on the University of California Berkeley campus.

 G.   DRY-SPRINKLER AND PRE-ACTION SPRINKLER SYSTEMS

 1.   All flooding (filling with water) of a dry-sprinkler and pre-action sprinkler systems will initiate a full alarm condition in the building fire alarm system. Sprinkler flooding will initiate an alarm both during a programmed alarm triggered flood (e.g., a cross-zoned smoke detector condition) and a manual flooding of the sprinkler via a manual lever.

 2.   All dry-sprinkler and pre-action sprinkler systems shall monitor the status of the piping integrity (low supervisory air pressure) at the building fire alarm control panel.

 H.   TAMPER SWITCHES

 1.   Each fire sprinkler shut off valve shall be provided with a tamper switch to supervise it electrically against undetected closure.

 2.   On hard-wired conventional systems, each tamper switch shall be wired to a tamper-switch zone in the fire alarm control panel. There shall be one such zone for each tamper switch. Tamper switches shall not be connected to flow switch zones.

 3.   On addressable alarm systems each tamper switch shall have a dedicated address.

 4.   Tamper switch activation shall not cause the building evacuation appliances to sound and light, nor light a lamp on an outdoor annunciator.

 I.   AUDIBLE/VISUAL SIGNALING DEVICES (INDICATING APPLIANCES)

 1.   Audible signaling devices shall be Cerberus/Pyrotronics.

 2.   Audible/visual devices shall be red in color.

 3.   At least one audible/visual indicating appliance shall be located so that its signal can be heard and seen at the fire alarm control panel, with any door(s) to the control panel room closed.

 4.   No audible indicating appliance shall be located within 20' of a fire alarm control panel or sub-panel, unless it is in a separate room with a door in between.

 5.   All audible signaling devices shall sound with uniform alarm code (3 beats, pause, 3 beats) as opposed to a continuous sound.

 6.   Sufficient audible/visual indicating appliances shall be provided so that fire alarms can be heard and seen in all areas of the building, including those which are only occasionally occupied, such as machine rooms, and electric rooms. All building remodeling projects in existing buildings shall provide for additional fire alarm indicating appliances if the remodeling would otherwise result in areas where the signals are not sufficient.

 7.   Audible/visual indicating appliances shall be designed to continue signaling until manually silenced by the fire department. No automatic time-out circuitry shall be used to silence the indicating appliances.

 8.   All fire alarm systems shall include audible/visual indicating appliances. Systems using silent alarms shall not be permitted.

 9.   A single alarm silence switch shall be provided inside the fire alarm control panel so that the alarm indicating appliances may be silenced without resetting the fire alarm system. If this switch is of the maintained-contact type, its position shall be supervised so that it cannot unknowingly be left in the silenced position. New alarm systems will be designed to accommodate subsequent alarms (alarms initiated after the alarm silence switch has been operated) by sounding and flashing the indicating appliances.

 10.   If full-size horns cannot be located so that adequate sound penetrates closed doors (sound levels from the full-size horns are too high), then mini-horn/strobes may be used inside the affected rooms. A example is the use of mini-horns inside dormitory bedrooms.

 11.   In laboratories where the level of sound provided by corridor indicating appliances is not adequate and because of the need to avoid starting laboratory occupants who may be engaged in potentially hazardous activities the following shall be installed:

   a.   Mini-horns (Cerberus/Pyrotronics type HDCM-24 or equivalent) shall be installed (in conventional alarm systems); laboratories.

   b.   New addressable alarm systems shall use voice alarm (Cerberus/Pyrotronics MXLV). Addressable voice systems allow speaker volume and sound levels to be adjustable inside laboratory applications.

11.   Mini-horns (Cerberus/Pyrotronics type HDCM-24 or equivalent) shall be installed (in conventional alarm systems) in laboratories where the level of sound provided by corridor indicating appliances is not adequate. Mini-horns or strobes are preferred for this application because of the need to avoid starting laboratory occupants who may be engaged in potentially hazardous activities.

 12.   The sound level provided in all areas by audible evacuation indicating appliances shall conform to the recommendations of NFPA 72. This requires at least 15dBA above the ambient sound level or 5dBA above the maximum sound level. These definitions and conditions are specified by the NFPA. This level of sound shall be provided in all areas, including those areas only occasionally occupied, such as mechanical equipment rooms. All sound measurements shall be performed while the space is completely occupied by its assigned tenants and while normal activities are in progress.

 13.   Addressable alarm systems Audible and Visual Indication Appliances (horn/strobes); The Audible and Strobe indicating appliances shall be fully synchronize where the light from more than two strobes may be seen at one time (large assembly areas, corridors, class rooms and atriums). Audible pulse rate and strobe flash shall be synchronized by device and by system. The "temporal" signaling pattern shall be used.

 14.   Audible and Visual Indication Appliances (horn/strobes); When visual indicating appliances (strobes and horn/strobes) are located where the light form more than two strobes may be seen at one time, large assembly areas, corridors, class rooms and atriums, than these appliances shall be on the same circuit. This will allow the use of synchronized hardware when required.

 15.   Addressable alarm systems Audible and Visual Indication Appliances (horn/strobes); In a Cerberus/Pyrotronics MXL system the use of Intelligent Control Points (ICPs) to control Horns, Speakers, and Strobes is not acceptable. Use the CSM-4 Conventional Signal Module. In a Cerberus/Pyrotronics MXLV system the horns, speakers, and strobes may be controlled with Zone Control Modules (for example, ZC2-8B)

 16.   Addressable alarm systems Audible and Visual Indication Appliances (horn/strobes); The use of any add-on or stand alone controls for indicating appliance drivers is not acceptable. This includes the use of alarm power adder and extended circuit units (Pyrotronics PAD-2 for example). If the alarm system must use additional remote mounted controls they shall be in the form of integrated remote panel (MXLR and MXLRV as an example).

 17.   Audible and Visual Indication Appliances (horns, strobes, and speakers) shall have back boxes provided by the manufacture for that use only.

 I-1.   BATTERY BACKUP

 1.   Battery backup shall be provided to power the fire alarm system in the event of AC power failure.

 2.   Battery capacity shall be determined in accordance with appropriate codes and industry practice. Battery capacity shall sized to include the 25% future expansion required by UCB.

 5.   Batteries shall be supervised to detect open circuits, short circuits, grounds and low battery voltage.

 6.   Batteries shall be located within or adjacent to the fire alarm control panels. Batteries located in a separate location or mounted above ceilings are not acceptable.

 7.   The use of small stand-alone power supplies and battery stand-by systems is not allowed. This is to include the use of power adder panels in remote locations, indicating appliance power adder panels and security-type power supplies.

 J.   DOOR RELEASES

 1.   Alarm-controlled door releases shall be of the simple electromagnetic type (Edwards Cat. 1508 or equivalent), as opposed to the integrated hydraulic closer type of door release.

 2.   Door releases shall have an operating voltage of 24 VDC.

 3.   Each door release circuit shall be independently fused at the fire alarm control panel. The fuse shall be chosen to open the circuit at 125% of normal current.

 4.   Electromagnetic door hold opens will be wired so as to be de-powered during AC power failure; alternatively electromagnetic door holders will included in the battery stand-by calculations.

K.   ALL DEVICES SHALL TRIGGER BUILDING CENTRAL ALARM SYSTEM

 1.   All alarm-initiating devices shall be wired so as to trigger the building central fire alarm system in the advent of an alarm. This includes (but is not limited to) elevator-recall smoke detectors, duct smoke detectors and devices that which are part of fire-extinguishing systems such as Halon, range-hood, and dry-sprinkler systems.

 2.   An exception to this requirement shall be bedroom and apartment areas, here local smoke detectors with integral horns are permitted.

L.   CONNECTION TO THE CAMPUS-WIDE FIRE ALARM SIGNALING SYSTEM

 1.   All building fire alarm systems shall automatically transmit all alarm signals to the University of California Police Department Communications Center. In addition to the two existing alarm transmission systems in use (Gamewell Master Box and Lease-line) a digital dialer (compatible with Cerberus alarms systems and the receiving equipment at the University of California Police Department Communications Center) shall be provided. The digital dialer will transmit code required alarm, supervisory, and trouble signals.

2.   In locations covered by the campus underground fire alarm loop (in general, the central campus), connection to that loop shall be provided via a Gamewell Three-Fold Master Box transmitter.

   a.   Each master box shall be connected to only one building and report alarms for only one building fire alarm system.

   b.   The master box shall be located indoors, immediately adjacent to the main fire alarm control panel. This fire alarm control panel and master box shall be located at the Berkeley Fire Departments point for primary response. This location is to be determined by the Authority Having Jurisdiction (Campus Fire Marshal).

   c.   The Master Box Transmitter shall be Gamewell type M34-72. There will be no substitutions. The master box will have a 4 digit code number that shall de determined in consultation with Capital Projects (CP). When purchasing a new Master Box and code wheel, refer to the "City of Berkeley specifications" which are on file with the Gamewell Company.

   d.   When an building fire alarm system is being replaced or upgraded and the existing Gamewell Master Box is an outdoor pedestal mounted cottage type, then the new installation shall be with an indoor configuration as above. The existing campus signal loop shall be extended into the building to the new master box location. The existing pedestal and pedestal mounted devices shall be removed and replaced with an approved Christy type hand hole as required.

 3.   In other locations, connection to the University of California Police Department shall be provided by means of a leased-line driver, integral to the building fire alarm control panel. This driver shall connect to a dedicated telephone line (hard-wired to the University of California Police Department's alarm receiving equipment).

   a.   The driver shall provide output current at; Normal Condition 4-11 Milliamps DC and Alarm Condition 4-11 Milliamps DC, reversed polarity.

   b.   Output of the leased-line driver shall be short-circuit protected (i.e. a short circuit on the output shall not result in damage to the driver or the rest of the fire alarm control panel).

   c.   Fire alarm system trouble and supervisory conditions shall not transmit to the UC Police Department by opening the fire alarm signals "Normal" status line signal. If trouble or supervisory signals are to be transmitted they shall be sent as separate signals over assigned hard-wired leased-lines.

   d.   Fire Alarm system signals shall not share transmissions with any other signal sources (do not send with Security, access control, or energy management signals).

   e.   Lease-line drivers shall not interfered with the ground fault detecting ability of fire alarm control panel. The panel must be able to supervise the building alarm wiring for the presence of electrical grounds, regardless of the condition of the hard-wired lease-line cable condition.

 4.   In locations where neither the Campus Alarm Signal Loop or the use of Lease-Line transmissions are available (no copper hard-wire telephone connection) a digital dialer is to be used for alarm transmission. The selection of the digital dialer Brand and model shall be submitted to Capital Projects (CP), UCPD, and PP-CS Technical Services for approval.

M.   ANNUNCIATOR PANELS

 1.   The requirement for and location of an annunciator shall be determined by the Authority Having Jurisdiction (Campus Fire Marshal).

 2.   An annunciatior panel is not required (unless required by the Campus Fire Marshal) if the following conditions are met:

 3.   If an annunciator panel is required it shall be located immediately inside the fire departments entry door. Only if that space is not available than the annunciator may be mounted on the outside wall near the fire departments entry door. Pedestal mounted annunciators are not acceptable.

 4.   Annunciators containing electronic components will not be mounted in outside locations. The only exceptions shall be mounting within approved (by Capital Projects) weather proof enclosures located in non weather or sun exposed locations (i.e. covered porches).

 5.   For addressable alarm systems the annunciator shall be a Cerberus/Pyrotronics RCC-1. This uses an alphanumeric display that is a one-to-one match with the display at the main fire alarm control panel. The remote annunciator shall be software configured as a "read-only" display.

 6.   For a hard-wired conventional alarm system, the annunciator shall be a directory-style annunciator (as opposed to a bull's-eye-style or a graphics -style). It shall indicate alarm conditions only, it will not indicate trouble or supervisory conditions. The design of a hard-wired annunciator shall be such that it will be capable of future expansion and modification. Annunciator design, brand and model shall be submitted to Capital Projects for approval.

N.   REMOTE TROUBLE ANNUNCIATOR

 1.   When the main fire alarm control panel is located inside a room that is not accessible to the public, and there is no remote inside annunciator of the addressable type (Cerberus/Pyrotronics RCC-1) showing panel status, a remote trouble annunciator may be required by the Campus Fire Marshal. The remote trouble annunciator shall be mounted in an appropriate public area (e.g., a corridor) so that trouble conditions can be noted and reported.

 2.   This remote trouble annunciator shall include both visual and audible alert signaling of trouble conditions on the main fire alarm control panel. If a "silence" switch is included it shall be key-operated. The public trouble notification must be by-passable from the control panel for routine maintenance operations.

 3.   The remote trouble annunciator shall not be part of an outdoor alarm annunciator.

O.   SINGLE RESET SWITCH

The main "RESET" switch in the fire alarm control panel shall reset all of the fire alarm controls, alarm initiating devices (smoke detectors and duct smoke detectors), and alarm indicating devices (audible/visual horn/strobes). The exception to this is specific application panels (range-hood chemical release systems). No additional switch shall be needed to reset smoke detectors, or daisy-chained sub-panels.

P.   SINGLE ALARM "SILENCE" SWITCH

A single switch, located in the main fire alarm control panel, shall silence all audible/visual alarm indicating appliances. The main fire alarm control panel is the panel which either trips the Gamewell Master Box or contains the leased-line driver, as described in this division.

Q.   BY-PASS SWITCHES

 1.   Addressable fire alarm systems (Cerberus/Pyrotronics MXL and Cerberus/Pyrotronics MXLV based systems) shall have software controlled by-pass switches.

   a.   These switches shall be on the auxiliary function key-pad and on the MXLV, VSM-1 (the Voice Switch Modules may be programmed as "generic switches" and function as "function key" switches). 

   b.   These supervised bypass switches shall be programmed to survive reset and to toggle on-off.

   c.   The by-pass switch software functions shall "by-pass" the alarm inputs and the outputs of the other control functions.

   d.   These by-pass switches shall be assigned to perform the following functions, one switch per function:

   - By-pass all audible/visual indicating appliances (including voice alarms).

   - By-pass Fire Department (alarm transmission to U.C. Police Department).

   - All Sprinkler flow switches and valve tamper switches. (one bypass switch for all).

   - By-pass all smoke detectors by floor (one switch each to bypass all smoke detectors on each floor).

   - By-pass all duct detectors (include Plenum high-velocity detectors).

   - Provide one bypass switch to by-pass "all fan and air handler shutdown".

   - one bypass switch to by-pass"; all smoke pressurization fans" (if applicable).

   - by-pass each panel controlled auxiliary activity (Halon release, dry-sprinkler flooding, range-hood suppressant release...etc.). This is to be configured as one by-pass switch per activity.

   - By-pass each alarm initiating input from auxiliary alarm system (Halon control panel, range-hood control ...etc.). This is to be configured as one by-pass switch per activity.

 2.   In hard-wired conventional systems supervised disconnect switches shall be provided to by-pass the following functions (supervised switches that are part of the specific control module are acceptable):

   - Municipal tie (central station signaling).

   - All audible/visual alarm signaling.

   - All door holder (including roll-down and accordion doors).

   - All extinguishing systems that are controlled by the fire alarm control panel (e.g., Halon systems, dry-sprinkler systems) one by-pass switch per system.

   - Elevator recall circuits.

   - Equipment shutdown or turn-on circuits (e.g., building fan shutdown and fan turn-one)

R.   SINGLE CIRCUIT BREAKER-DEDICATED CIRCUIT

 1.   All 120 VAC fire alarm equipment within a building shall be fed from one single circuit breaker. This includes the fire alarm control panel and all auxiliary equipment. The exception is roll down fire shutters and accordion-type fire doors .

 2.   The circuit breaker shall be clearly labeled Fire Alarm System and shall be fitted with a clip to prevent it from being turned off.

 3.   No other (non-fire-alarm) equipment shall be fed by this circuit breaker.

 4.   Where there is an emergency 120 VAC system available the fire alarm and fire alarm auxiliary equipment shall be on the emergency panels.

 5.   All 120 VAC fire alarm equipment within the building shall be fed from dedicated circuits. This includes all fire alarm control panels and auxiliary equipment. Each motorized fire doors shall have a separate dedicated circuit (accordion and roll-down doors and enclosures).

S.   SINGLE KEY

Within any building, all locked fire alarm equipment , such as control panels, sub-panels, manual pull stations, and key switches, shall have one common key.

T.   NO CONNECTION TO SECURITY ALARM SYSTEMS

All fire alarm systems shall be totally separate from security alarm systems. No common wiriness, raceways, batteries, control panels or signal transmission systems shall be used.

U.   MORE THAN ONE STRUCTURE

When more than one structure is served by a single fire alarm control panel, an alarm initiated in one structure shall cause the audible/visual devices to sound only in that structure. The silencing of the audible devices in one or more structures shall not prevent the sounding and flashing of subsequent alarms in an other structure. When possible the U.C. Police shall receive a separate alarm signal for each structure in alarm.

V.    WIRE TYPES AND SIZES

 1.   Manufacturer's recommendations as to wire size and type will be followed.

 2.   Stranded wire is not to be used on any part of the fire alarm system. The single exception shall be factory provided internal wiring with factory provided termination.

 3.   Cerberus/Pyrotronics will provide specific wiring direction for addressable alarm systems. This will include the use of shielded and non-shielded twisted pair cable.

   i.   A nearby remote indicating lamp to indicate when that device is in alarm condition.

   ii.   Professional signage, adjacent to the alarm devices; so that the fire response personnel and maintenance personnel may easily locate them (example: "smoke detector 002-032 above ceiling").

   iii.   All system-connected alarm devices in locations with restricted access shall have remote indicating lamps labeled as above, in the nearest public access area. (Examples: system-connected smoke detectors in apartments, residence suites, or bedrooms; detectors in areas which are not accessible using the usual building master keys, areas such as duct detectors inside fan rooms and plenum spaces).

   3.   Addressable alarm systems shall have the following labels on all inciting and control devices:

   a.   A professional (Brother P-Touch- type) clear label with black lettering on each alarm initiating device, smoke and heat detector base, visible from the floor, giving the address of the device.

   b.   Each Intelligent Interface Relay (Cerberus/Pyrotronics TRI) shall have the device address displayed on the back mounting box cover, visible to the fire department and maintenance personnel without necessitating the removal of any cover or equipment.

   c.   All panel and sub-panel labeling shall be typed on appropriate card stock (function key labels on Cerberus/Pyrotronics MXL and MXLV control panels).

   d.   Each alarm detection device shall have its address marked on the back of the plug-in unit and base.

LL.   LIMITATIONS ON CONTRACTOR ACCESS

 1.   No outside contractor shall access an existing fire alarm control panel or any other part of an existing fire alarm system unless the system has first been appropriately shut down or secured by the University fire alarm staff. When the contractor is finished, the system shall be re-energized or reconnected by the University fire alarm staff.

 2.   When a new fire alarm system is completed, the final connection to the campus-wide fire alarm signaling system shall be performed by the University fire alarm staff. "Final connection" shall be interpreted to mean the physical connecting of wires or similar action, and not the installation of equipment or wires.

MM.   STATE FIRE MARSHAL APPROVAL

 All fire alarm equipment and devices shall be California State Fire Marshal listed. All drawings and specifications for fire alarm installations shall be submitted to the Campus Fire Marshal's office for review and approval. Drawings and specifications shall be approved by the University for construction only after receiving the Campus Fire Marshalís stamp of approval, including signature and date.

NN.   APPROVAL BY FIRE PROTECTION ENGINEER

 All drawings and specifications for fire alarm installations shall be approved by a fire protection engineer licensed in the State of California. Drawings and specifications shall be approved by the University for construction only after receiving the fire protection engineerís stamp of approval, including signature and date.

OO.   TRANSFER OF SOFTWARE.

 One month prior to the end of the warranty period, the Cerberus/Pyrotronics licensee holding the software shall (if requested by the University) ship a disk containing the entire program to another Pyrotronics licensee designated by the University. This transfer shall be done at no additional charge. The original licensee shall remain responsible for warranty service and for any other software changes until the end of the warranty period; the new licensee will not be permitted by the University to access the system until the original warranty has expired. If the original licensee makes any changes to the software subsequent to shipping the disk, it shall immediately ship another disk containing the revised program to the licensee, at no additional charge.

PP.   NO FAN SHUT DOWN VIA OTHER CONTROL SYSTEMS

 All fire alarm fan shut down functions must be via listed fire alarm equipment. Fire alarm conditions must shut down fans directly, not through a control system like the Barrington Energy Management System. The use of relays in addition to the relays incorporated in the fire alarm devices is not allowed. The preferred method for fan shut down is for the control signal to the fan motor control contractor coil be interrupted directly by the fire alarm control relay (e.g., Cerberus/Pyrotronics TRI intelligent relay interface, or the programmable relay in the duct smoke detector housing). All fan control relays in an addressable fire alarm system shall be controlled by the custom software logic (Cerberus/Pyrotronics CSGM software). This will allow the full control of auxiliary relays and fans from the menu driven fire alarm control panel. The use of default relays is not allowed. This section applies also to the control of air dampers by the fire alarm system.
