Notification, Architects and engineers specifications – Cooper Bussmann POWERPATH PS-6 User Manual

Page 4

The power supply shall be Wheelock POWERPATH™ Series PS-8, or equivalent. The unit shall be stand alone power supply intended

for powering fire alarm notification appliances via its own Notification Appliance Circuit(s) (NAC). The unit shall be UL 864 Listed for

power limited operation of outputs and comply with NFPA 70 (NEC), article 760.

The power supply 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 supply shall be activated by a standard Notification Appliance Circuit (NAC) from any Fire Alarm Control Panel (FACP) or a

“Dry contact” opening. The units shall be 8 ampere, 24 VDC, regulated and filtered, supervised remote power supply/charger. It shall

operate over the voltage range of 8 to 33 VDC or FWR. The primary application of the unit shall be able 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 supply shall provide four Class “B”, two Class “A”, or two Class “B” and one Class “A” NAC circuit(s). Eight

Class “B” or Four Class “A” circuits shall be available with an optional PS-EXP module. The PS-8 unit shall supply up to 240 mA of

auxiliary power that is available during both non-alarm and alarm or auxiliary power of not less than 2.5A at 24 VDC during non-alarm.

The power supply shall be capable of charging batteries of up to 33 ampere hours per NFPA 72 at maximum rate of 0.750 Amps per

hour.

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 supply 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 trouble terminals. The power supply shall be powered from a 120 VAC source with a current consumption of xx

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 0.129 Amps max. The power supply shall have the ability to latch trouble LED’s so the circuit in

trouble can be identified. The cabinet dimensions shall be 17” H x 15” W x 5.5” D.

The power supply shall be Wheelock POWERPATH™ Series PS-6, or equivalent. The unit shall be stand alone power supply intended

for powering fire alarm notification appliances via its own Notification Appliance Circuit(s) (NAC). The unit shall be UL 864 Listed for

power limited operation of outputs and comply with NFPA 70 (NEC), article 760.

The power supply shall support a full 6A of notification power even if the battery is in a degraded mode and only AC power is

connected.

The power supply shall be activated by a standard Notification Appliance Circuit (NAC) from any Fire Alarm Control Panel (FACP) or a

“Dry contact” opening. The units shall be 6 ampere, 24 VDC, regulated and filtered, supervised remote power supply/charger. It shall

operate over the voltage range of 8 to 33 VDC or FWR. The primary application of the unit shall be able 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 supply shall provide four Class “B”, two Class “A”, or two Class “B” and one Class “A” NAC circuit(s). Eight

Class “B” or Four Class “A” circuits shall be available with an optional PS-EXP module. The PS-6 unit shall supply up to 200 mA of

auxiliary power that is available during both non-alarm and alarm or auxiliary power of not less than 2.5A at 24 VDC during non-alarm.

The power supply shall be capable of charging batteries of up to 33 ampere hours per NFPA 72 at a maximum rate of 0.750 Amps

per hour.
