Example Ancillary Board Connection
Power Fault (PF)
Power Fault (PF) is unused on the Ancillary Board and is designated as a No Connect (NC) terminal.
Configuring Status Units and Ancillary Boards
Status units and ancillary boards require a four-wire connection from the fire control panel, which drops into each unit
and connects to the corresponding data and power, in and out terminals. Two of the cables carry power to the units
(24V) and the other two carry data. A four core cable suitable for carrying RS485 data should be used.
Each status unit has a 3-bit DIP switch and must be allocated a unique address between 1 and 7. Each ancillary board
has a 3-bit DIL switch and must be allocated a unique address between 1 and 7. The address switch is located on the
bottom left hand corner of the status unit or ancillary board PCB.
The address is only read when the boards are first powered so address switches should not be altered on a system that
has power applied. If a double address occurs on the system then the system will illuminate the General Trouble and
Abort indicators and the buzzer will sound. The panel display will show the status unit or ancillary boards that have the
same address.
