3.2 Initiating Device Circuits
Zones
Wire all alarm initiating devices sequentially for proper supervision. Initiating devices include: manual pull
stations, heat, photoelectric, and ionization type detectors; and waterflow alarm devices. Refer to the
Device Compatibility Chart.
Notes:
1) Observe polarity when connecting polarized devices.
2) All circuits are supervised and power limited.
3) Leave Dummy Load (provided) on all unused circuits.
