Wheelock POWERPATH NAC power supply data sheet

Technical Data TD450003EN NAC Power Supply Wheelock POWERPATH PS 8 LP by Eaton is a supervised power supply battery charger in a low profile cabinet that is for supervision and expanded power driving capability of fire Notification Appliance Circuits NAC The PS 8 LP is filtered regulated and provides 8 amps of power distributed across 4 power supplies may be connected to any 12V or 24V FWR DC Fire Alarm Control Panel FACP by using a NAC or a Primary applications include NAC expansion supports ADA and auxiliary power to support system accessories unit provides filtered and regulated 24VDC up to four 4 Class two 2 Class or two 2 Class and one 1 Class Appliance Circuits With the optional plug in PS EXP the unit supports 8 Class or 4 Class Notification Circuits Additionally an auxiliary power output of 2.5 disconnected upon AC power loss or an alarm condition or to 0.240 A of constant power on the PS 8 LP Wheelock power supplies can accommodate 7 AH batteries its lockable chassis Using an external battery cabinet it can up to 33 AH batteries pending UL testing Two FACP NAC or two contact initiating circuits can be connected to inputs These inputs can then be directed to control supervision power delivery to any combination of the four 4 outputs Each is rated at 3.0 Amps Class or Class and can be to generate a steady or Code 3 temporal horn sound a strobe output under alarm condition Total load for PS 8 LP circuits must not exceed the power supplies rated output power supplies under non alarm condition provide independent for Class and Class FACP NAC circuits In event of circuit trouble the FACP will be notified via the steered input IN1 or IN2 In addition there are two of trouble reporting terminals one used for AC power loss and the other for all troubles The AC power loss reporting the common trouble terminals and on IN1 or IN2 can be delayed either 30 seconds or 170 minutes The AC power loss terminals always report the trouble within 1 second after loss of AC PS 8 LP power supplies are UL listed under UL Standard 864 Edition to be used with any 24 volt listed regulated notification They include the capability to synchronize Wheelock and horns and to silence the horn signal when horn strobes operating on two wires October 2017Supersedes December 2015 PS 8 LPfirealarmresources com 120VAC 50 60Hz 4.25 Amps and 5.32 Amps Operating Power Automatic switch over to standby batteries when AC fails Supports sealed lead acid or gel type batteries NAC Power Supply Power Not battery dependent Fused battery protection Thermal and short circuit protection with auto reset Approvals Include UL Standard 864 UL 1481 Supports 7AH batteries Compliance Compliant with NFPA 72 Factory Mutual FM Operating Modes refer to Installation Manual Normal Mode Provides constant 24 VDC output upon initiation a voltage to input IN1 or IN2 or by a contact opening on or DRY2 The unit returns to standby mode when the is deactivated Wheelock Sync Mode Provides signals for synchronization of Wheelock audible and strobe notification appliances can also be silenced in this mode while the strobes to flash Sync Mode Accepts a synchronization signal on the to provide a coded output or synchronized output This may come from a FACP another POWERPATH or a DSM synchronization module Caution Do not use on coded output circuits True Input Follower Mode Accepts a coded signal on the input provide a coded output with the same timing as the input signal may come from a FACP another POWERPATH or coded source Caution Do not use strobes on coded circuits Temporal Mode Codes the output voltage in a code 3 temporal to drive audible appliances such as horns bells or Caution Do not use strobes on coded output circuits Data TD450003EN October 2017 Low Profile Alarm
