MOUNTING
Mount the unit to a firm vertical surface. The wall wiring hole
should be no more than 5/16" (8mm) diameter.
1. Remove the front cover by twisting a screwdriver blade in the
groove between cover and base at the bottom edge of the case
and then lifting the cover off.
2. Remove the circuit board: Loosen (do not remove) the vertical
adjustment screw, slide the PC board down, then spread the
PCB holding tabs (see Figure 3), and remove the PC board.
3. Break out desired mounting and wire entry holes in the back
case. Refer to Figure 2. Knockout screw holes “A” in the back
case are for normal surface mounting on a wall. Knockout screw
holes “B” are for corner mounting.
Also break out the wire entry hole marked X in Figure 2. If
surface wiring is to be used, break out the section at the bottom
of the back case, and run the wiring up the wiring channel at
the back of the case to hole “X”.
If the back case tamper is to be used, use an additional screw
through hole C to secure the back case to the mounting surface.
4. Feed wiring (unpowered) coming from the wall through the wire
access hole near the top of the detector case back. If surface
wiring is used, use bottom access hole and use the wiring
channel in the case back for routing the wires.
5. Mount the base and reinstall the PC board.
6. Vertically align the PC board in accordance with Table 1
(Vertical Pattern Adjustment section below) before
tightening the vertical adjustment screw.
7. Refer to WIRING CONNECTIONS section before replacing cover.

WIRING CONNECTIONS
All wires should have been fed through the wire access slot at the
top of the detector base near the terminal block. Connect polling
loop wiring to the screw terminals as shown in Figure 3. Seal any
openings in the base with foam or RTV (not supplied) to prevent
drafts and insects from entering the unit. Apply power only after all
connections have been made and are inspected.
VERTICAL PATTERN ADJUSTMENT
The protection pattern can be moved up or down by vertical
adjustment of the lens as follows.
1. Remove the front cover as indicated in step 1 of the
MOUNTING section.
2. Loosen the PCB screw on the lower right of the board (see Fig.
3), and slide the board into the appropriate position, using the
scale to the right of the screw. Use Table 1 which shows the
proper setting for the desired range.

HORIZONTAL PATTERN ADJUSTMENT
The protection pattern can be moved to the left or right by horizontal
adjustment of the lens, as follows.
1. Remove the front cover as indicated in step 1 of the MOUNTING
section.
2. Remove the lens holder in the front cover by squeezing the two outer
sides of the holder together, releasing it from the side clips (see
Figure 4). Then pull the holder out, exposing the lens.
3. Slide the lens slightly to the left or right to change the horizontal
pattern as desired.
4. Reinstall the lens holder. It should snap firmly in place beneath the
holding tabs on each side.
5. Replace the front cover.
IMPORTANT: After any adjustment, conduct a walk test to ensure
proper coverage of the area to be protected. See the
Test Procedures section.
