Architects and Engineers Specifications
The power supplies shall be Wheelock POWERPATH™ Series PS-12/24-8CP or PS-12/24-8MP, or equivalent. The units shall
be stand alone power supplies intended for powering fire alarm notification appliances via their own Notification Appliance Circuit(s)
(NAC). The units shall be UL 864 Listed for power limited operation of their outputs and comply with NFPA 70 (NEC), article
760.
The power supplies shall support a full 8A of notification power even if the battery is in a degraded mode and only AC power
is connected.
The power supplies shall be activated by a standard Notification Appliance Circuit (NAC) from any Fire Alarm Control Panel (FACP)
or a "Dry contact" closure. The units shall be 8 ampere, 12 or 24 VDC, regulated and filtered, supervised remote power supply/
chargers. The power supplies shall provide a full 8 amperes of current and shall not be battery dependent. They shall operate
over the voltage range of 8 to 33 VDC or FWR. The primary application of the units shall be to expand fire alarm system
capabilities for additional NAC circuits to support ADA requirements and to provide auxiliary power to support system accessories
or functions. The power supplies shall provide four Class "B", two Class "A", or two Class "B" and one Class "A" NAC circuit(s).
The PS-12/24-8CP units shall also supply up to 200 mA of auxiliary power that is available during both nonalarm and alarm.
The PS-12/24-8MP units shall also supply auxiliary power of not less than 3.5A at 24 VDC during nonalarm. The power
supplies shall be capable of charging batteries of up to 12 ampere hours per NFPA 72 (1999). Input activation options shall be
from not less than two NAC circuits or Dry Contact closures. These inputs shall have the capability of being directed to any
combination of the four NAC circuit outputs. Each NAC circuit output shall be rated at 3 amperes for Class "B" applications or
3 amperes each for Class "A". The outputs shall be programmable to generate a steady or Temporal (Code 3) output and or
a synchronized strobe or horn output. The power supplies shall provide independent loop supervision for either Class "A" or
Class "B" FACP NAC circuits and shall have the capability to "steer" all alarm or trouble conditions to either incoming NAC
circuit. The units shall have common output terminals. The power supplies shall be powered from a 120 VAC or 240 VAC
source with a current consumption of 5 amperes max. The unit shall incorporate short circuit protection with auto reset. The
power supply shall incorporate a built in battery charger for lead acid or gel type batteries with automatic switchover to battery back
up in the event of AC power failure. The charger shall incorporate fused protection for the batteries and have the ability to report
low battery and/or no battery condition(s). Standby current for battery back up shall be 100 mA max. The cabinet dimensions
shall be 16" H x 12.25" W x 5" D.
