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).

Recess Mounting

Recessed mounting requires the use of the

optional No. 1990MK Recess Mounting Kit.

Complete instructions for the use of this kit

accompany it.

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."

Note:

Holes "C" in the

the

lens

supports

are

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

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.
