Remove the front cover as shown in Figure 1.
Remove the screw holding the PC board in the
detector base (the screw is located at the center
of
the
board) and temporarily
remove the board
@andIs PC board carefully).
Refer to Figure 2. Knockout holes in the base are
availa&
for normal surface mounting on a wall
(holes 'A'). or for comer mounting (holes '8').
Break out only those mounting holes required.
Feed wiring emerging from the wall through the wire
access slot at the bottom of the detector base.
Make sure wires have sufficient sbdr lo allow the
PC board lo slide up and down freely when the
wires are subsequently connected lo the terminals
on the board. Then mount the base.
Re-install lhe PC board (with renninal block dosest
to the wiring access slot in the base). Before fully
lightening the holding screw, make sure the board
is positioned tor the appropriate selling on the
graduated
scale
(see
'B.

B. Vertical Pattern Adjustment
The prelection pattern provided by the lens in Use Can
be raised or lowered by re-positioning the PC boatd n
the detector. A graduated scale to Ihe right of the
board (see Fig. 3) indicates the approximate number of
degrees by which the pattern can be raised (max. l 4 '1
or lowered (max. W). The detector is normally shipped
with the board set to the 0" positlon. To make this
adjustment. remove the cover on the detector and
loosen the screw holding the PC board (the screw is
located at the approximate center of the board). Slide
the board upward or downward by the
number
of
degrees required, lhen tighten the holdi
screw again.
After any adjustment. you must conduct a walk test 10
ensure proper coverage of the area to bs protected. as
indicated under Test Procedures-.
C. Lens Masklng:
The masking strips lhal have been supplied are
designed for application to one or more lens segments
to prod&Y? a protection pattern pattern that suits the
parlicular
.requirements
of the protected
area.
lndiiual
masking slrips have been provided
for
each
of the lens segments on the standard lens supplied
with the PIR. Simply peel off the appropriate pressure-
sensiliie adhesive strip(s) and apply over the desired
IenS segment(S). Be sure lo affix the masking strips lo
the inside of the lens (not the outer, smooth ade).
Each lens segment that is masked results in the
elimination of one zone of protection from the coverage
paltern. By masking segments of the lens. you can
adjust lhe coverage lo suit the area lo be prolected. or
eliminate coverage from areas where you anticipate
environmental
disturbances
that might reduce the
PIRL stabilii (a heater or
other
heat-producing objecl
for example).
WIRING CONNECTIONS
Bring all wires in through the wire access slot near the
terminal bk& and conned lo the screw terminals (see
Fig. 3 for wiring details). Beal all openings in the base
wilh loam or RTV (not supplied) lo prevent drafts or
insects from entering the unit. Apply power on/y after
aI/ amfx3cMns haue
been made and are &pee&d.
