7.6.1 Four-Wire Smoke Power (regulated)
This terminal is labeled 4-WIRE SUPPLY on the circuit board. 4-wire smoke power is provided
for 4-wire smoke detectors. This filtered supply is supervised therefore a short will disconnect
the power through the relay until the “RESET” key is pressed. This supply is rated at 22.3VDC
regulated/300mA max/1V voltage drop maximum.
7.7 Supervised Auxiliary Power (regulated)
This terminal is labeled AUX SUPPLY on the circuit board. Supervised auxiliary power is used
to power the Remote Annunciators and Smart Relay Modules. This filtered circuit is
supervised, therefore a short will disconnect the power through the relay until the SYSTEM
RESET button is pressed. This supply is rated at 22.3VDC regulated/500mA max/1V voltage
drop maximum.
7.8 Auxiliary Power (unregulated)
This terminal is labeled UNFILTERED on the circuit board. This unregulated supply is not
supervised. This supply is rated at 24VDC/1.7A maximum. If there is a short on this circuit, the
auxiliary power does not recover automatically when the short is removed. The main power
must be disconnected, then reconnected and the panel reset to re-establish the auxiliary
power supply.
