CAUTION! Make certain all power (AC and DC) is removed before any replacement work is performed.
FACP Main Circuit Board, Transformer and Chassis Removal
The FACP Main Circuit Board replacement kit consists of the Main Circuit Board and Transformer mounted on the Chassis. For
ease of replacement, the entire assembly should be replaced as a complete unit.
1. If a 4XTM Series module is installed and/or the onboard DACT (Digital Alarm Communicator/Transmitter) is connected, notify
the monitoring service before proceeding with the main circuit board replacement.
2. Make certain AC power has been turned off at the main service circuit breaker. Disconnect the AC wiring from the Transformer
and disconnect the battery cable from connector J1 of the FACP main circuit board.
3. Label and remove all field wiring from terminal blocks TB1, TB2, TB3, TB5, TB6 and TB7 on the main circuit board.
4. Disconnect the DACT telephone lines from connectors PH1 and PH2.
5. If a 4XTM Series module is installed, remove the two mounting screws and carefully unplug the module from connectors J8 &
J9. Set screws and module aside for installation on the new main circuit board.
6. Loosen or remove the two chassis mounting nuts (3/8") which secure the chassis tabs to the backbox.
7. Lift the chassis assembly from the mounting slots in the backbox.

This Product Installation Document outlines the replacement of the Main Circuit Board, Transformer and
Chassis for the Fire Alarm Control Panel with 50 addressable points. Proper grounding of the individual
performing the replacement and the work area, is essential to prevent circuit board damage due to
Electrostatic Discharge. Accepted industry practices must be employed.
Note: All hardware, (chassis, screws, nuts, standoffs, etc.) required to mount the main circuit board and
option module, is included in the main circuit board replacement kit, in the event any of the original
hardware is misplaced during the circuit board removal and installation. This hardware is not required if
the original hardware is removed from the old circuit board.
