NO/NC (normally open / normally closed) relates to the fire detection system's normal
status.
2.9 Detector circuits, circuit driver 1 (circuits 1 and 2) and
circuit driver 2 (circuits 3 and 4)
The periphery board (500p) has two independent integrated circuit cards. Each
integrated card is a driver that has 2 circuits that can handle a maximum of 252
devices. Circuit driver 1 supports circuits 1 and 2 and circuit driver 2 supports circuits 3
and 4.
Each circuit driver can be configured for two style 6 circuits or four style 4 circuits:
The detector circuits are isolated from the periphery board's main circuit. Each circuit
card has a microprocessor which supervises ground fault, short-circuit, open circuit,
and line capacity.
