Installing the Detector
All wiring must conform to National Electric Code (NEC) and/or
local codes having jurisdiction.
Important:
DO NOT use this device for safety
interlock applications.
Use the following steps to install the detector:
1. Run the security system wiring to the detector location.
2. To remove the front cover/electronic module, press down on
the lever at the bottom of the unit and pull the cover off.
Remove the nameplate and loosen the screw if necessary. To
remove the nameplate, insert a small screwdriver into one of
the nameplate side slots and gently push in on the nameplate.
See Figure 1.
CAUTION!
Use anti-static precautions when handling
the circuit board.
3. If necessary, set the jumpers on the circuit board. See
Setting
the Jumpers
.
4. Remove the appropriate wiring and mounting knockout holes
from the back cover. The detector can be mounted on a flat
wall or in a corner. See Figure 3.
5. Pull the wires through the knockout holes and use the two
screws provided to attach the base to the wall. Use screw
anchors if necessary.
6. Strip 1/4 inch of insulation from each wire.
7. Run each wire through the strain relief and under the appro-
priate screw terminals on the base and tighten the screws.
See Figure 3.
8. Line up the tabs on the bottom of the cover/electronic module
with the corresponding tabs on bottom of the base and snap
the cover/electronic module firmly down onto the base.
9. Tighten the screw and replace the nameplate. See Figure 1.
10. Apply power. The green LED should light for approximately
25 seconds and then go out.
11. Walk test the coverage pattern as follows:
Walk throughout the intended coverage area.
Verify the detector alarms. See
Understanding the LED
.
Note:
Most units walk test more accurately if the person
testing waits 10 seconds between tripping the unit and
walking again. This allows the detector to stabilize between
trips.
