Detector Circuits, Circuit Driver 1 (Circuits 1 and 2) & Circuit Driver 2 (Circuits 3 & 4)
The peripheral board (252p) has one independent integrated circuit card, and the
periphery board (504p) has two independent integrated circuit cards. Each integrated
card is a driver that has two circuits that can handle a maximum of 252 devices. Circuit
driver 1 supports circuits 1 & 2 and circuit driver 2 supports circuits 3 & 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.
