3. Provide battery back-up as secondary power supply. Provide back-up battery and battery
charger each with 20% spare capacity for future use. Design battery back-up to take over
supply to system instantaneously. Provide battery with adequate capacity to be capable
of operation of system for 60 hours under normal supervisory (non-alarm) conditions and
then for 15 minutes under alarm conditions. Battery charger shall completely recharge
batteries within 48 hours. Batteries shall be sealed gel-cell maintenance free type.
E. Wiring System Materials: Provide basic wiring materials which comply with SECTION
260533 - RACEWAYS, SECTION 260534 - ELECTRICAL BOXES AND FITTINGS, and
SECTION 260516 - WIRE AND CABLES.
1. Provide wire and cable in accordance with requirements of manufacturer, except as
noted.
2. Conductor sizes shall be AWG No. 14 or larger 600V, Type THHN or TFFN, with
maximum 19 strands copper conductor, 7 strands for sizes AWG No. 16 and No. 18.
3. Provide conductors with crimp on terminal ends.
4. Provide conductors which are listed and approved for fire alarm usage.
5. Do not provide multi-conductor fire alarm cables.
6. Provide labeling on all termination points.
7. Provide separate conduits for supply and return loops per NFPA 72 Class A System.
8. Provide labeling at all termination, junction and pull boxes. Labeling shall be engraved,
plastic labels that identify the zone and circuit contained.
F. Fire Alarm Control Panels (FACP): Provide fire alarm control panel enclosures for housing
devices and circuits necessary to perform required functions to service test points and to
service trouble-signal points. Control panel shall comply with UL 864. Cabinet shall be
lockable steel cabinet. Provide 10 keys to Contracting Officer.
1. FACP shall be addressable.
2. Provide control panel for operation on 120Vac supply and for 24Vac system operation
with integral battery standby power source.
3. Equip control panel for number of initiating zones indicated plus 10% (but not less than
six spare modules).
4. Provide TVSS protection of 120Vac power supply at the fire alarm control panel in a
separate, adjacent enclosure.
G. The Mass Notification functions shall override the FACP Notification functions. The system
shall have the capability of utilizing a remote microphone station with redundant controls of
the notification system control panel. Class "A" Notification Appliance Circuits (NAC) shall
be provided for the activation of strobe and speakers appliances. The activation of the NAC
Circuits shall follow the operation of the speaker NAC circuits. Audio output shall be
selectable for line level (600 ohms), 25, 70.7 or 100V output. The audio amplifier outputs
shall be not greater than 100 watts RMS output. Amp shall have 50% spare capacity. The
strobe NAC Circuits shall provide at least 2 amps of 24Vdc power to operate strobes and have
the ability to synchronize all strobes. A hand held microphone shall be provided and, upon
activation, shall take priority over any tone signal, recorded message operation in progress,
while maintaining the strobe NAC Circuits activation.
1. All outputs and operational modules shall be fully supervised with on-board diagnostics
and trouble reporting circuits. Form "C" contacts shall be provided for system alarm and
trouble conditions. Circuits shall be provided for operation of auxiliary appliance during
trouble conditions. During a Mass Notification event the panel shall not generate nor
