A223 Action on Hearing Loss Smoke Alarm

5.3 CONNECTING MORE THAN ONE DETECTOR (continued)
1. Open the cover of the first SMOKE DETECTOR (supplied as
standard) and locate the screw terminal that the standard 10m
cable is attached to.
2. Remove the cable from the screw terminal by unscrewing the
terminal screws.
3. Cut the required length of “interconnect” cable to connect the
first SMOKE DETECTOR to the second SMOKE DETECTOR
and strip the ends.
4. Connect both the standard 10m cable (that plugs into the
JUNCTION BOX 3 ) and the “interconnect cable” to the
screw terminal in the first SMOKE DETECTOR, making sure
that the connections are tightened correctly.
5. Open the cover of the second SMOKE DETECTOR (optional)
and locate the screw terminal.
6. Connect the other end of the “interconnect cable” to the
screw terminal in the second SMOKE DETECTOR, making
sure that the connections are tightened correctly.
7. Using wire cutters remove the resistor, R56, from the screw
terminal circuit board in the first SMOKE DETECTOR only.
8. When installing more than one additional SMOKE
DETECTOR repeat steps 1-6 above, connecting the third to
the second, the fourth to the third etc.
IMPORTANT: When installing more than one additional
SMOKE DETECTOR each SMOKE DETECTOR screw
terminal circuit board should have resistor R56 removed as in
step 7 above, apart from the last SMOKE DETECTOR
in the line.
