12. 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.
13. Pull out the detector terminal strip and connect the four wires to the terminal strip as follows
(see Figure 7).
• Connect the wire corresponding to the detector’s red wire to the
LEL “R”
terminal.
• Connect the wire corresponding to the detector’s white wire to the
LEL “W”
terminal.
• Connect the wire corresponding to the detector’s green wire to the
LEL “G”
terminal.
• Connect the wire corresponding to the detector’s black wire to the
LEL “B”
terminal.
CAUTION:
If shielded cable is used, leave the cable shield’s drain wire
disconnected and insulated at the detector junction box. You will
connect the opposite end of the cable’s drain wire to the M2A junction
box’s chassis (earth) ground.
