CONNECTION (CONTINUED)
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.
