9.3.2 CONNECTION
There are various connection possibilities depending on the particular local requirements for
Standby and Isolate, and the loop resistance. One or two AZCs may be required.
Where Standby is required as a separate signal at the Main FIP it can be signalled as Alarm
on a second AZC and the corresponding zone programmed as non-MAF, non-Anc1, etc.
Isolate could be signalled as "Fault" on the same AZC (ref Fig 9.3.1 and Fig 9.3.2).
The Main FIP Brigade Standby and Isolate relays could be reprogrammed to include the
"standby" zone "alarm" and "fault" conditions, or separate module relays could be
programmed to operate on the zone "alarm" and "fault" conditions. These would then be
connected to the Brigade transmitting device in series/parallel with the Standby and Isolate
contacts of the MAF Brigade relays as appropriate.
Note that the EOL required depends on the mode programmed for the AZC.
