For corner mounting, see B. Corner Mounting. Also break out the
desired wire entry hole at this time, marked X1 or X2 in Figure 3.
3. Feed wiring emerging from the wall through the wire access hole.
Make sure wires have sufficient slack to allow the PC board to be
moved up and down freely when the wires are connected to the termi-
nals on the board.
4. Mount the base. A level may be used on the front case to ensure that
the unit is vertical (see Figure 2). Replace PC board. Note the
mounting orientation of this detector: terminal strip at the bot-
tom! Make sure the board is positioned to the appropriate setting (see
Figure 7).
5. Refer to the WIRING CONNECTIONS section before replacing the
front cover.
B. Corner Mounting
Knockout holes "B" in the base are used for corner mounting on a
wall. Mount in selected corner with 4 screws. Replace PC board.
Note the mounting orientation of this detector: terminal strip at
the bottom!
Make sure the board is positioned to the appropriate setting (see
Figure 7).
C. Changing Lenses (if required)
1. Remove front cover.
2. Release the lens support frame located in front cover as follows:
Insert the blade of a small screwdriver between the locking tab and
the detector case in each of the two corners of the frame, and lever
each tab upward to release. See Figure 4. When both corners are
released, remove the lens support frame by lifting and sliding the two
remaining corners away from the stops in the front case.
3. Remove the existing lens and replace with the replacement lens. The
lens must be installed with the smooth side facing outward.
Also, the lens should be oriented with the notches at the top. Be
sure to center the lens with the notches aligned with the protrusions in
the front case.
Note: Lens surface should be free of dirt, foreign matter, and finger-
prints. Use a clean, dry, soft cloth to wipe lens surfaces.
4. Insert the lens support frame into its original position and then press
downward on the frame so that the lens locking tabs snap into position
in each of the four corners.
5. Replace front cover.

WIRING CONNECTIONS
Bring all wires in through the wire access hole and connect to the screw
terminals (see Figure 5 for wiring details). Seal any openings in the base
with foam or RTV (not supplied) to prevent drafts or insects from entering
the unit. Apply power only after all connections have been made and are
inspected.
LED ENABLE/DISABLE OPTION
See Figure 3 for location of LED enable/disable jumper link.
To enable the LED, remove the LED enable/disable jumper link. To dis-
able the LED, replace the jumper link. See Figure 6 for proper positioning
of the link.
