Relay #2 [Smoke Detector Power Reset]
Relay #2 can be used as a smoke detector reset or as dry contacts as shown below:
Smoke Detector
To utilize relay #2 as smoke detector power reset connect a jumper between terminals 33 and 24
to power the smoke detectors.
UL Listed smoke detectors: ESL model 445AT
This hookup applies to the connection of smoke detectors to the hardwired zones of the
control panel.
Smoke detector power ranges from 10.2 and 14.0 volts. The maximum voltage available for
smoke detectors is 100mA from terminals 32 and 33. Additional power is available through the
other aux. power outputs providing that the total power being used does not exceed the rated
values of the outputs and that the total power consumed does not exceed the standby
requirements. Consult the aux. power section for further information.
The unit has been designed to operate with four wire smoke detectors and end of line relays
for supervision of the power to the detectors. Listed below are some recommended smoke
detectors and EOL relays:
Gentex Model #6040 & 6041
Voltage 10 - 16 VDC, standby 5mA, Alarm 60mA
ESL Model # 445AT
Voltage 5.1 - 16.5VDC, standby 1.5mA, Alarm 100mA
Power supervision End of Line relay Model 204A
Standby 40mA at 12VDC
BRK System Sensor Model # 2412 or 2412TH
Voltage 11.3 - 17.3, standby 120mA, Alarm 77mA
End of line relay model # A77-716-01
Standby 25mA at 12VDC
