1. Notify the applicable local fire department and/or alarm receiving station that the system is being serviced.
2. Inform all personnel in the facility that testing is in progress, from the start of servicing to its completion.
3. Reference the systems Installation Wiring Diagram (IWD) for specific connection and component information.
4. Disconnect any and all auxiliary alarm devices. (Solenoids, system shutdowns, etc.)
5. Disconnect ALL system power and lock out (both Primary AC power and Battery Backup power) and verify the system is
shut down. Failure to disconnect all power can result in personal injury and/or damage to equipment.

1. Follow the “Initial Steps” above.
2. Detach the Display Panel (DP-1067, DP-1079 or DP-1151) covering the card to be replaced by removing the two mount-
ing screws and set aside.
3. Note the position of the card to be removed. Replacement should be installed in the same position. Grip the card by the
ejector handles at each end of the card and pull gently from the expansion slot edge terminal. Pull the card out straight and
evenly. Do not pull out one end of the card at a time as this may damage the connector.
4. Line up the replacement card with the expansion slot edge terminal noting the polarity of the card. Pin 1 of the edge termi-
nal will be at the top. Gently slide the card into the expansion slot. Push the card in straight and evenly. Do not insert one
end of the card at a time as this may damage the connector.
5. With the card inserted, replace the Display Panel being sure to properly tighten the mounting screws.
6. See “Final Steps.”

Follow the “Initial Steps” above.
1. Remove mounting screws of board to be replaced and adjacent boards if necessary. Some boards, depending on position,
cannot be removed without dismounting adjacent boards.
2. Lift the board off its mounting standoffs being sure to disconnect it from any interconnection to an adjacent board.
3. Disconnect and tag each wire terminated on the board, including field wiring, factory wiring and harnesses.
4. Remove the board from the system and substitute with its replacement. Re-terminate all wires, referencing each wires tag
for terminal designations. Reconnect all wiring harnesses to their proper interface terminals.
5. Remount all circuit boards to their proper mounting standoffs being sure to reconnect all board-to-board interconnections.
Make sure no wires are pinched between the board and its mounting standoffs before tightening the mounting screws.
6. See “Final Steps.”
