Admissible cable cross-section: 1 x 12…18 AWG or 2 x 16…18 AWG
NO/NC (normally open / normally closed) relates to the fire detection system's normal
status.
1.9 Detector circuits, circuit driver 1 (circuits 1 and 2)
The periphery board (250p) has one independent integrated circuit card. This
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 can be configured for two circuits
(style 6) or four circuits (style 4).
The detector circuits are isolated from the periphery board's main circuit. The circuit
card has its own microprocessor for supervising ground fault, short-circuit, open circuit,
and line capacity.
