The PS-95 Power Conditioning Module is designed to provide filtered, regulated DC power from a full wave rectified source

(FWR). The module can provide 26 VDC power to devices such as UV/IR detectors, Gas Detectors, Fiber Optic Controllers and

Four Wire Smoke Detectors. This module also provides both resettable or non resettable outputs, either may be utilized depending

on what the application requires.

26 Volt Non-regulated power (FWR) is fed into the PS-95 power input terminals from either the primary system power supply

(MB-91) or an auxiliary power supply (PS-91 Option “W”). This power has an inherent battery backup which provides battery backup

for the power conditioning module. The power conditioning module filters and regulates this power providing either resettable or non

resettable field terminations. Resetting can be implemented in three ways: (1) the module may be wired into the system reset buss and

will reset when the system reset switch is depressed, (2) the module has an on board reset switch which can be depressed to manually

reset, or (3) a remote N.O. reset switch may be used (see wiring diagram below). When the module is regulating system power, the

“A.C. ON” (Green) indicator is illuminated. When the module is on battery backup, the “BK-UP ON” (Yellow) indicator is illuminat-

ed. During battery backup, the modules regulation is bypassed and battery power is supplied directly to the output terminals. This

avoids unnecessary voltage drops to devices powered by the module when on batteries. Since the PS-95 power is common to the

system power, its output is monitored for ground faults by the systems built in ground fault detector. To implement power supervision

to field devices supplied by the PS-95, a power supervisory relay (PSR-2040) must

be used (see wiring diagram below and 4 wire

detector power supervision page of this manual) unless the devices used have a means of supervising their own power source.
