Smoke Detector Reset
Output 1 may be used to reset 4-wire smoke detectors.
Use this output to trigger a low current relay, and wire
the power for the smoke detectors through the relay’s
contacts.
NOTE: The output is normally high (12VDC) and goes
low when the User Code + Off is entered at the keypad.
To install a relay for smoke detector reset, perform the
following steps:
Step Action
1
Connect power terminals of the relay to the
panel’s auxiliary power (terminals 6 & 7).
2
Connect trigger input of the relay to Output 1
on J7.

the
“pole” (common) of the relay to
terminal 6 of the control.
4
Connect the positive side of the smoke
detectors to the normally closed contact of the
relay.
5
Connect the negative side of the smoke
detectors to terminal 7 of the control.
