Wire all alarm initiating devices sequentially for proper supervision. Initiating devices include
manual pull stations, waterflow alarm devices, and heat-, photoelectric-, and ionization-type
detectors. Refer to the Device Compatibility Document for compatible devices.
Notes:
1. Observe polarity when connecting polarized devices.
2. All circuits are supervised and power-limited.
3. Leave dummy load resistor (provided) on all unused circuits.
