F3200 IS CIRCUIT USING 6-TERMINAL REPEATERS
Relay or Open Collector
For each AZC there must be either: a corresponding relay (e.g. Module Relay RLn) with
normally closed contacts breaking the supply to the Isolator as shown; or an open collector
output switching the supply 0V as shown. As the open collector is standard with an 8ZM it is
the cheapest alternative.
Programming & Limitations
All detector types require the circuit to be programmed for Mode 1 (Std) with voltage band
B1 programmed as Alarm.
The open collector must be programmed as OCn = ^ZnR, or the Relay must be programmed
as Rn = ZnR (i.e. Zone n not in Reset or Zone n in Reset respectively).
There is no
differentiation of voltage bands (B1, B2, B3), i.e. the FIP cannot differentiate
between short-circuiting MCP and detector operation on the same circuit.
