FACP Keypad/Display Removal
Removal of the keypad/display is normally not necessary. If, however, it becomes necessary to
replace the keypad/display, access the auxiliary trouble bus connectors at J16 and J17 or install the
DACT-UD2 option module on J2, the Keypad/Display can be removed by inserting a Phillips
screwdriver into each of the three holes located in the flexible covering of the Keypad/Display and
loosening the three mounting screws. Note that it is not necessary to disconnect the cables between
the Keypad/Display and the main circuit board unless the unit itself is being replaced. Carefully lift
the Keypad/Display and rest the unit at the bottom of the main circuit board.
!
WARNING: RISK OF ELECTRICAL SHOCK AND EQUIPMENT DAMAGE
DISCONNECT ALL SOURCES OF POWER (AC AND DC) BEFORE INSTALLING OR REMOVING
ANY MODULES OR WIRING.
NOTE: When installing the DACT-UD2, the main motherboard must be removed from the
chassis. Unplug the power supply cable from J1 before proceeding.
