INSTALLATION
IMPORTANT: For installation with pets, be
sure to follow the guidelines described in
Table 2.
Radio Transmission Path Check
Verify that a strong transmission path
between the 5890PI and the system's
Receiver/Control exists before permanently
mounting
the
detector.
performing the Walk-Test (described later)
with the detector temporarily mounted in its
proposed location. The 5890PI will transmit
when sensing motion (waving an arm or
walking into an area). Sometimes, moving the
detector only a few centimeters means the
difference between a strong and weak
transmission path. Experiment until you are
satisfied that the location provides the
strongest transmission path, yet is still
practical for the protection pattern desired.
This test also verifies that the detector has
been correctly programmed into the system.
Normal Mounting
Mount the unit to a firm vertical surface (flat
on a wall or in a corner).
1. Remove the front cover.
2. Temporarily loosen (do not remove) the
screw holding the PC board in the
detector base (see Figure 5 for location of
this screw).
The board can then be moved up or down
for access to the knockout mounting holes
in the base.
3. Refer to Figure 3 for location of knockout
holes in the base. Break out only those
holes required.
4. Mount the detector with screws, using the
selected mounting holes.
5. Before fully tightening the PC board
holding the screw, make sure the board is
positioned so that the arrow is in line with
the appropriate setting on the graduated
scale on the right-hand side of the PC
board (see Table 1 and Figure 5).

detector base (accessible only when the PC
board is removed) are used for recessed
mounting.
Changing Lenses (if required)
Do this by
1. Remove front cover.
2. Squeeze upper lens lock located in front
cover to release upper Fresnel lens
support. Squeeze lower lens lock to
release lower Fresnel lens support (see
Figure 4).
3. Note
how
positioned, then remove the supports.
4. Carefully remove the existing lens and
replace it with an optional coverage
replacement lens. The lens must
installed with the smooth side facing
outward . Also, the lens should be oriented
with its part number on the upper right -
hand side (see Figure 4). Be sure to center
the lens.
Note: Lens surface should be free of dirt,
foreign matter and fingerprints. Use a
clean dry soft cloth to wipe lens surfaces,
if required.
5. Replace top and bottom lens supports and
then press downward so that the lens
locks snap into position, thus securing the
lens in place.
6. Refer to Table 1 for recommended PIR
mounting height.
7. Replace the front cover (make sure the
cover snaps tightly).

Vertical Pattern Adjustment
The protection pattern provided by the lens in
use can be raised or lowered by repositioning
the PC board in the detector. A graduated
scale to the right of the board (see Figure 5)
indicates the approximate number of degrees
by which the pattern can be raised (max. +5 )
or lowered (max. -15 ). The detector is
normally shipped with the board set to the 0
position. 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, then tighten the
holding screw again. After any adjustment,
you must conduct a Walk-Test to ensure
proper coverage of the area to be protected, as
indicated under "Test Procedures."

Lens Masking
The supplied masking strips are designed for
application to one or more lens segments to
produce a protection pattern that suits the
particular requirements of the protected area.
Individual masking strips have been provided
for each of the lens segments on the standard
lens supplied with the PIR. 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. By
masking segments of the lens, you can adjust
the coverage to suit the area to be protected,
or eliminate coverage from areas where you
anticipate environmental disturbances that
might reduce the PIR's stability (a heater or
other heat-producing object, for example).
Horizontal Adjustment of Lens
The protection pattern provided by the lens
can be moved to the left or right by horizontal
adjustment of the lens, as follows:
1. Remove front cover.
2. Press inward on the upper and lower lens
locks at the left or right side only to
release the lens supports on one side. Now
slide the lens to the left or right, as
needed. The lens may be moved as much
as 8 from center in either direction.
3. When the lens is in the desired position,
press the lens locks downward on the
released side to lock the supports in place.
4. Replace the front cover (make sure the
cover snaps tightly).
After any adjustment, you must conduct a
Walk-Test to ensure proper coverage of the
area to be protected, as indicated under "Test
Procedures."
PULSE COUNT OPTION
Each detector includes Pulse Count circuitry
that is designed to provide stability in
adverse environments to minimize false
alarms. Pulse count is selected by positioning
a jumper across the ON pulse count terminals
(shown in Figure 5). When set for pulse
count ON, the detector will signal an alarm
within 2 or 3 steps, since the processing logic
requires more complex motion than just a
momentary event. When the detector verifies
an intrusion, the built-in transmitter will
send
an
alarm
message
control/receiver.
Important Note: For installations with
pets, Pulse Count ON is recommended.
LED DISABLE
The detector is shipped with the LED
disabled (LED jumper in the "NORMAL"
position). The LED may be enabled (for the
Walk-Test) by positioning the LED jumper in
the "TEST" position (see Figure 5).
Note: When the jumper is in the "NORMAL"
position, the LED will not light, but the built -
in transmitter will transmit alarms when the
PIR senses motion.
