GENERAL INFORMATION

These passive infrared motion detectors are versatile wall-mounted

units employing Fresnel lenses and offering efficient protection pat-

terns for commercial and residential applications. Best coverage will

be obtained if mounting is selected such that the likely direction of

intruder motion is across the pattern.

When installed per the guidelines, the Split-Zone Optics technology in

the 998PI and 998EXPI (with tamper switch) provide reasonable false

alarm protection against pets and other animals up to 40 lbs.

Special Instructions

for Installations Containing Pets

To take full advantage of the pet immunity in the 998PI or 998EXPI,

the following guidelines should be followed:

• Mount the center of the detector 6-1/2 to 7-1/2 feet (2.0m - 2.3m)

high and adjust the vertical angle according to Table 1.

• Set the PIR sensitivity for Standard (STD).

• Mount where animals cannot come within six feet of the detector

by climbing on furniture, boxes, or other objects.

• Do not aim the detector at stairways that can be climbed by animals.

Note: This unit will provide immunity to false alarms for an individ-

ual animal or a group of animals whose total weight is equal to or

less than 40 pounds when the room temperature is above 50¡F (10¡C).

INSTALLATION

For optimal pet immunity performance, be sure to follow all the guide-

lines described in the section ÒSpecial Instructions for Installations

Containing Pets.Ó

A. Normal Surface Mounting

Mount the unit to a firm vertical surface. The wall wiring hole should

be no more than 5/16Ó (8mm) in diameter.

1. Remove the front cover as shown in Figure 1.

2. Refer to Figure 2. Knockout holes ÒAÓ in the base are for normal

surface mounting on a wall (slide PC board up for access to bottom

holes, down for access to top holes). For corner mounting, see B.

Corner Mounting. Also break out the desired wire entry hole at

this time, marked X1 or X2 in Figure 2).

3. Feed wiring emerging from the wall through the wire access hole

near the top of the detector base. Make sure wires have sufficient

slack to allow the PC board to be moved up and down freely when

the wires are connected to the terminals on the board.

4. Mount the base. Note the mounting orientation of this detec-

tor Ð wire entry at the top, lens at the bottom! Make sure the

board is positioned so that the arrow is in line with the appropriate

setting on the graduated scale (see Figure 5 and Table 1).

5. Refer to the WIRING CONNECTIONS section before replacing the

front cover.

B. Corner Mounting

Knockout holes ÒBÓ in the base are used for corner mounting on a

wall (slide PC board up for access to bottom holes, down for access

to top holes). Mount in selected corner with 4 screws.

Note the mounting orientation of this detector Ð wire entry at

the top, lens at the bottom! Make sure the board is positioned so

that the arrow is in line with the appropriate setting on the gradu-

ated scale (see Figure 5 and Table 1).

C. Changing Lenses (if required)

1. Remove front cover.

2. Release the lens support frame located in front cover as follows:

Insert the blade of a small screwdriver between the locking tab and

the detector case in each of the four corners of the frame, and lever

each tab upward to release. See Figure 4. When all four corners are

released, remove the lens support frame.

3. Remove the existing lens and replace with the replacement lens.

The lens must be installed with the smooth side facing out-

ward. Also, the lens should be oriented with its part num-

ber 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 fin-

gerprints. Use a clean dry soft cloth to wipe lens surfaces.

4. Insert the lens support frame into its original position and then

press downward on the frame so that the lens locking tabs snap

into position in each of the four corners.
