5. Refer to E. Vertical Pattern Adjustment and Table 1 for recom-
mended detector pattern setting for various mounting heights and
protection ranges.
6. Replace front cover.
D. Horizontal Adjustment of Lens
The protection pattern can be moved to the left or right by horizontal
adjustment as follows:
1. Remove front cover.
2. Release the lens frame as shown in Figure 4.
3. Grasp the lens firmly on both sides (front and back) and slide the
lens to the left or right, as needed. The lens may be moved as much
as 4¡ (from center) in either direction.
4. Replace lens, lens frame and the front cover.
After adjustment, conduct a Walk-Test to ensure proper coverage of
the area to be protected (see TEST PROCEDURES).
E. Vertical Pattern Adjustment
The protection pattern can be raised or lowered by repositioning the
PC board in the detector. A graduated scale to the left of the board
(see Figure 5) indicates the approximate number of degrees by which
the pattern can be raised (max. +5¡) or lowered (max. -20¡). To make
this adjustment, slide the board upward or downward by the number
of degrees required. After any adjustment, conduct a Walk-Test to
ensure proper coverage of the area to be protected (see TEST PROCE-
DURES).
Table 1 indicates the recommended setting at various mounting
heights.
F. Lens Masking
The supplied masking strips can be used to produce a protection pat-
tern that suits the particular requirements of the protected area, or
eliminate coverage from areas where you anticipate environmental
disturbances that might reduce the PIRÕs stability (a heater or other
heat-producing object, for example). Simply peel off the appropriate
pressure-sensitive adhesive strip(s) and apply over the desired lens
segment(s). Be sure to affix the masking strips to the inside of the
lens (not the outer, smooth side). Each lens segment that is masked
results in the elimination of one zone of protection from the coverage
pattern.

WIRING CONNECTIONS
Bring all wires in through the wire access slot at the top of the detec-
tor base (near the terminal block) 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
To enable the LED, set the DIP switch #1 DOWN (see Figure 5 for
switch location). To disable the LED, set DIP switch #1 UP. Use a
small pointed tool to move the switch handle up or down.
PULSE COUNT OPTION
For Intermediate Pulse Count, set the Pulse Count DIP switch #2
UP (see Figure 5 for switch location). For Standard Pulse Count,
set DIP switch #2 DOWN. Use a small pointed tool to move the
