Honeywell / ADEMCO PS24 Power Supply Module GENERAL INFORMATION The PS24 power supply module is an accessory for Honeywell control panels intended for use in commercial fire installations. The PS24 has two triggerable 24VFW (full wave rectified, unfiltered), 1.7A Class B, Style Y outputs that can either provide 24VFW auxiliary power, or can convert up to two control panel 12VDC EOLR supervised bell circuit outputs to 24VFW EOLR supervised bell outputs. Each of the PS24 outputs, labeled OUTPUT A and OUTPUT B, has a corresponding controlling input, labeled INPUT A and INPUT B, respectively. Negative voltages applied to INPUT A and INPUT B are passed through to the associated output, allowing the control panel to supervise bell circuit wiring connected to that output (as required for installations which use the output for 24VFW, EOLRsupervised bell circuit operation). Applying positive voltages of 9.5–14VDC to INPUT A and INPUT B produces 24VFW at the respective output terminals. For installations which require 24VFW auxiliary power, you must wire INPUT A and/or INPUT B to the control panel's 12VDC auxiliary power terminals so that the associated PS24 output remains activated continuously. For installations which require 24VFW EOLR supervised bells, you must wire INPUT A and /or INPUT B to the controls panel's 12VDC EOLR supervised bell terminals. Primary power for the PS24 power supply module is supplied by a 1451-24 transformer, which consists of an AC power transformer and a manually resettable circuit breaker mounted inside a protective enclosure. The 1451-24 transformer has two secondary windings – a 30VAC/188VA winding which is used to power the PS24 module, and an 18VAC/72VA winding which is used to power the control panel. The PS24 module monitors its connection to the 1451-24 and can report a low AC condition to the control panel via one of the control panel's EOLR supervised zones. Secondary power for the PS24 power supply module is supplied by a pair of 12VDC lead-acid (gel cell) batteries rated at 7AH minimum, 17.2AH maximum. Both batteries connect directly to the PS24 module which internally configures them to provide 24V back-up power for its outputs, and 12V back-up power for the control panel. The PS24 module charges and tests these batteries and can report a low or disconnected battery condition to the control panel via one of the control panel's EOLR supervised zones.
