Figure 7. 2-Wine Smoke Detector Connected to Zone 1
Wdng 4-W- SmokdCombuetion Detectors on Zones 2-7
The system will support as many 4-wire detectors as can be powered from
Auxiliary Power on the control on zones 2-7. Refer to the detector's
instructions for complete details regarding its proper installation and
w
operation.
1.
2.
Connect 12 volt power for the detectors horn Auxiliary Power terminals 4
and 5, (which will interrupt power for fire alarm reset). Observe proper
polarity when connecting detectors.
Connect detectors (includirw heat detectors. if used) across terminals of
the zone selected (zones 2-7"may be used). W dete~rs must be wired in
parallel.
3. To supervise power, we recommend the use of a System Sensor
No. A77-716B supervisory module.
