8 XR2500F Fire Detection Specification
4.13 Power Supplies
A. Power supplies for the FACP shall operate from 120 VAC, supplied at the respective protected areas.
Power supplies shall be all Solid State.
B. The FACP shall have a 24 VDC 4 Amp power limited supply for Notification Appliance Circuits (NAC) with
up to 6 Amps peak power available for inrush current demands.
C. Standby batteries shall be supplied to power the system in the event of a utility power failure. Controls
shall be designed to maintain full battery charge when alternating current power is available. The
system shall be automatically transferred to battery power upon loss of alternating current (AC) power
and return to alternating current (AC) power upon restoration. Standby batteries shall be sealed lead-
acid.
D. The system shall be capable of connecting multiple Model 504-24LX Addressable Power Boosters that are
controlled and supervised by the digital SLC loop. Each Power Booster shall have a 24 VDC 4 Amp power
limited supply with up to 6 Amps peak power available for inrush current demands. Each Power Booster
shall also have two (2) independent Class B Style W Notification Appliance Circuits (NAC) that are
controlled and supervised by the digital SLC loop.
E. The FACP shall be capable of operating for twenty-four (24) hours on battery standby with five (5)
minutes of alarm signaling at the end of this twenty-four (24) hour period (as required by NFPA 72
Central Station Signaling requirements), or sixty (60) hours on standby battery with five (5) minutes of
alarm signaling at the end of this sixty (60) hour period (as required by NFPA 72 Remote Station Signaling
requirements).
F. Controls shall be designed to maintain full battery charge when alternating current is available.
Batteries shall be capable of being recharged to 85% capacity within twenty-four (24) hours from battery
use. A signal shall be initiated upon failure of battery or alternating current power.
G. Approved power supplies shall meet or exceed the following power supply model specifications:
• UL Listed DMP 505-12: 12 VDC 5 Amp with transformer and enclosure.
• UL Listed DMP 504-24: 24 VDC 4 Amp with transformer and enclosure.
4.14 Transformers
The FACP shall be provided with two transformers. One transformer shall be rated for 16 VDC and support
the FACP panel. The other transformer shall be rated for 28 VDC and support the built-in 4 Amp 24 VDC
power supply for the NAC circuits.
4.15 Serial Interface
The FACP shall be capable of a serial interface to output information to a standard serial printer or serial
interface to a communication port on a standard computer. Through FACP programming the system shall
include a provision to allow the selection of which reports are to be output through programming of the
FACP.
4.16 Control Designations
Controls shall be provided to ensure ease of operation of all specified characteristics. Controls, switches,
visual signals and indicating devices, input and output connectors, terminals and test points shall be clearly
marked or labeled on the hardware to permit quick identification of intended use and location.
