Guidelines for field wiring include the following:
Notification circuits are supervised, power limited and can connect to an
energy-limited cable.
Use only the compatible, UL-listed notification appliances listed in Device
Compatibility Document.
Wire notification appliances according to the manufacturer's instructions.
Maximum current per circuit is 3.0 amps. Maximum current per module
depends on the type of power supply (MPS-400 or AVPS).
Canadian installations require model N-ELR End-of-Line Resistor Assembly
(Style Y only).
Size wiring for no more than a 2-volt drop (loss) at the last device on the
circuit.
For zone coded applications, refer to the UZC-256 manual.
The ICM-4 is California Code programmable (microprocessor Rev. B or
higher). To program for California Code, cut diode D35.
