Warranty Information

No specific warranty period is mentioned in the provided document excerpt.

The HPF24S series power supplies are compact, cost-effective remote power supplies and battery chargers. They provide 24 VDC outputs for Notification Appliance Circuits (NACs) and can be configured for Style Y (Class B) or Style Z (Class A) with an optional module. They can also be configured as 24 VDC resettable or nonresettable power outputs.

The units feature supervised input/control circuits compatible with 12 VDC and 24 VDC control panels. They offer programmable features via DIP switches, including synchronization type selection, master/slave synchronization mode, AC fail reporting delay, and input/output function programming.

Key features include a lockable cabinet, power-limited outputs, integral supervised battery charger, and selectable strobe synchronization. They are designed for easy installation with fixed terminal blocks for wiring.

Troubleshooting and error codes

SW1 DIP Switch ON OFF
1 This switch works in conjunction with switch 2 to determine the Strobe Synchronization Type 1.
  • 1 OFF, 2 OFF = no sync (steady +24V) - default
  • 1 OFF, 2 ON = System Sensor
  • 1 ON, 2 OFF = Gentex
  • 1 ON, 2 ON = Wheelock
2 See switch 1 above.
3 HPF24S configured for Slave Synchronization HPF24S configured for Master Synchronization - default
4 Delay AC Fail Reporting for 2 Hours - default
Aux. Trouble Relay responds to all troubles.
Internal trouble contact responds to AC loss		 No Delay in AC Fail Reporting
Aux. Trouble Relay responds only to AC Fail/brownout.
Internal trouble contact will not respond to AC loss.
5 This switch works in conjunction with switch 6 to determine Input to Output functions
6 5 OFF, 6 OFF = General Alarm - default
  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is ignored.
  • HPF24S configured as Slave (switch 3 ON), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is monitored3.
  • Resettable or nonresettable Auxiliary Power Output is available from TB4 Terminals 9 & 10. Control Input #2 determines if reset will occur (must go from On to Off for a 6 second reset to occur).
  • Output #4 function follows DIP switch 8 setting.
5 OFF, 6 ON = Split Alarm
  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 & 2 are controlled by Control Input #1 and Outputs 3 & 42 are controlled by Control Input #2; Sync Input is ignored.
  • HPF24S configured as Slave5 (switch 3 ON), NAC Outputs 1 & 2 are controlled by Control Input #1 and Outputs 3 & 42 are controlled by Control Input #2; Sync Input is monitored3.
  • Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
  • Output #4 function follows DIP switch 8 setting.
5 ON, 6 OFF = Split Temporal
  • HPF24S configured as Master (switch 3 OFF), Control Input #1 controls NAC Outputs 1 & 2 and Control Input #2 controls Outputs 3 & 42 which will generate a Temporal code signal without sync; Sync Input is ignored. HPF24S configured as Slave (switch 3 ON), Control Input #1 controls NAC Outputs 1 & 2 and Control Input #2 controls Outputs 3 & 42 which will generate a Temporal code signal without sync; Sync Input is monitored for Outputs 1 & 23.
  • Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
  • Output #4 function follows DIP switch 8 setting.
5 ON, 6 ON = Selective Silence
  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is ignored.
  • HPF24S configured as Slave (switch 3 ON), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is monitored3.
  • Control Input #2 determines when Selective Silence for all outputs will occur4
  • Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
  • Output #4 function follows DIP switch 8 setting.
 5 OFF, 6 OFF = General Alarm - default
  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is ignored.
  • HPF24S configured as Slave (switch 3 ON), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is monitored3.
  • Resettable or nonresettable Auxiliary Power Output is available from TB4 Terminals 9 & 10. Control Input #2 determines if reset will occur (must go from On to Off for a 6 second reset to occur).
  • Output #4 function follows DIP switch 8 setting.
5 OFF, 6 ON = Split Alarm
  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 & 2 are controlled by Control Input #1 and Outputs 3 & 42 are controlled by Control Input #2; Sync Input is ignored.
  • HPF24S configured as Slave5 (switch 3 ON), NAC Outputs 1 & 2 are controlled by Control Input #1 and Outputs 3 & 42 are controlled by Control Input #2; Sync Input is monitored3.
  • Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
  • Output #4 function follows DIP switch 8 setting.
5 ON, 6 OFF = Split Temporal
  • HPF24S configured as Master (switch 3 OFF), Control Input #1 controls NAC Outputs 1 & 2 and Control Input #2 controls Outputs 3 & 42 which will generate a Temporal code signal without sync; Sync Input is ignored.

  • HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is ignored.
  • HPF24S configured as Slave (switch 3 ON), NAC Outputs 1 through 42 are controlled by Control Input #1; Sync Input is monitored3.
  • Control Input #2 determines when Selective Silence for all outputs will occur4
  • Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
  • Output #4 function follows DIP switch 8 setting.
7 Disable Charger Enable Charger - default
8 Output Circuit #4 = Door Holder Output Circuit #4 = NAC - default

1 Strobe Synchronization only works with non-coded NACs.

2 If Door Closer function is selected (switch 8 ON), Output 4 does not function as an NAC, therefore sync input is ignored for it.

3 If no synchronization is selected by switches 1 & 2, the Sync Input is ignored.

4 Selective Silence allows the silencing of the sounder portion of a horn/strobe combination device without turning off the strobe.

5 When using Split Alarm with power supply configured in Slave Mode, System Sensor can not be used (Use System Sensor with Master Mode only).
