Wiring the M2A Transmitter
WARNING: Always verify that the power to the M2A is off before you make wiring
connections.
1. Confirm that no power is being applied to the M2A.
2. Remove the junction box cover.
3. Grasp the control PCB by its edges.
4. Gently pull until the control PCB is pulled away from the banana jacks. Take care not to pull
too hard and damage the cable which connects the control and terminal PCBs.
5. Let the control PCB hang by the cable. The terminal strips are now visible on the terminal
PCB. The control PCB may be left hanging while wiring is done. If desired, the control PCB
may be disconnected from the cable and set aside while wiring.
6. The detector leads are factory wired. Verify that the detector leads are wired to the detector
terminal strip as shown in the figure below.

7. To gain access to a plug-in terminal strip for wiring, pull it out of its socket by grasping the
wall between two terminal positions with needle nose pliers and pulling. Be careful not to
exert too much force on the wall to avoid damage to the terminal strip. The detector terminal
strip and the alarm 1 relay terminal strip may be removed by grasping them with your fingers
if the adjacent terminal strips have been removed.
