Wiring 4-Wire Smoke/Combustion Detectors on Zones 2–7
You can turn off Fire alarm sounding by pressing the OFF key on any keypad or
other arming/disarming device in that partition. To clear the "memory of alarm"
and to reset the detectorÕs alarm, enter the security code plus OFF again.

Figure 8. 2-Wire Smoke Detector Connected to Zone 1
The system will support as many 4-wire detectors as can be powered from
Auxiliary Power on the control on zones 2Ð7. Refer to the detectorÕs
instructions for complete details regarding its proper installation and
operation.
1. Connect 12 volt power for the detectors from Auxiliary Power terminals 4
and 5, (which will interrupt power for fire alarm reset). Observe proper
polarity when connecting detectors.
2. Connect detectors (including heat detectors, if used) across terminals of
the zone selected (zones 2Ð7 may be used). All detectors must be wired in
parallel.
You must connect the EOL resistor across the loop wires at the last detector.
Remove 2000 ohm EOL resistor if connected across the selected zone
terminals.
3. To supervise power, we recommend the use of a System Sensor
No. A77-716B supervisory module.
