This wireless motion sensor includes the following features:

ˎ Field-selectable coverage area; 33 or 50 feet
ˎ Field-selectable sensitivity modes; 2-pulse or 4-pulse

ˎ 135-second transmitter lockout time after an alarm that

helps extend battery life

ˎ Cover-activated tamper
ˎ Supervisory signal transmitted every 64 minutes to the

control panel

ˎ Sensor low battery reports (trouble) to the control panel
Included with the sensor is a thin cardboard under-crawl

mask and snap-in plastic masks (installed at the factory).
Self-adhesive masking strips are also included.

Installation Guidelines

If possible, locate sensors within 100 feet of the panel. While
a transmitter may have an open-air range of 500 feet or
more, the installation site can have a significant effect on
transmitter range. Changing the sensor location may help
overcome adverse wireless conditions.

ˎ Mount the sensor permanently on a flat wall or in a

Product Summary

The AP750W Wireless PIR (passive-infrared) Motion Sensor
detects movement by sensing the infrared energy emitted
from a body as it moves across its field of view. When this
motion is detected, the sensor transmits an alarm signal.

Install motion sensors to protect areas where door/window
sensors are impractical or not needed. For example, use a
motion sensor to protect large areas or open floor plans.
Motion sensors can also provide backup protection in areas
where door/window sensors exist.

corner. Do not set it on a shelf.

ˎ For installations without pets, the required mounting

height is 7½ feet.

ˎ Mount the motion sensor on an insulated, outside wall

facing in.

ˎ Mount the motion sensor on a rigid surface which is free

from vibrations.

ˎ Position the sensor so it faces a solid reference point,

like a wall.

ˎ Do not aim the sensor at windows, fireplaces, air

conditioners, heaters/heating vents, or place it in direct
sunlight.

ˎ Position the sensor to protect an area where intruders

are most likely to walk across the detection pattern (see
Figure 1: Overhead View Walking Across Detection
Pattern).

Figure 1: Overhead View Walking Across Detection

Pattern

ˎ Do not mount the sensor near duct work or other large

metallic surfaces which may affect the RF signals (see
“Final Testing” on page 4). Actual acceptable transmitter
range should be verified for each installation.

ˎ Windows should be closed in any area which has an

armed motion sensor.

ˎ The cardboard under-crawl mask installed at the factory

(see Figure 2) blocks coverage within 5 feet of the
sensor.

Figure 2: Cardboard Under-crawl Mask Location

ˎ For installations where pets are present, mount the

sensor upside down about 3.5 feet above the floor (see
Figure 3). Leave the factory-installed under-crawl mask
in place to block any detection pattern directed at the
ceiling.

Figure 3: Pet Alley Application

Tools and Supplies Needed

ˎ Phillips screwdriver
ˎ Anchors and screws for mounting (included)
ˎ Masks (included)

Note: The cardboard under-crawl mask should remain

installed when sensor jumper J1 is set to the BI
position. See the section “Setting the Sensor
Coverage Area and Sensitivity” for complete
information on sensor jumper settings.

Mounting the Sensor

This section describes how to mount the sensor on a flat wall
or in a corner.

Note: Remove the factory-installed plastic masks before

mounting. Re-install as desired after walk testing.

Caution: You must be free of all static electricity before

handling sensor circuit boards. Touch a grounded,
bare metal surface before touching circuit boards
or wear a grounding strap.

Figure 6: Mounting Hole Locations

1. Remove the small cover (see Figure 4).

Figure 4: Removing the Small Cover

2. Open the sensor housing by pressing down on the top
rear and pulling the front cover at the top (see Figure 5).
Set the front cover aside.

Setting the Sensor Coverage Area and
Sensitivity

Jumper J1 determines the sensitivity mode of the sensor,
either standard or bi-curtain. Jumper J2 determines the
coverage area of the sensor, either 33 or 50 feet. See Figure
7 for jumper positions.

Use the standard (STD) setting for wide-angle coverage and
single curtain pattern. Use the bi-curtain (BI) setting for
added stability to help reduce false alarms. This mode
requires intruders to be detected by two curtains of
coverage.

Note: Do not use the bi-curtain mode for detection in areas

within 5 feet of the sensor. When selecting bi-curtain
mode, always leave the cardboard under-crawl mask
installed.

Caution: You must be free of all static electricity before

handling sensor circuit boards. Touch a grounded,
bare metal surface before touching circuit boards
or wear a grounding strap.

3. Mount the sensor on a flat wall or in a corner, using the
appropriate mounting holes (see Figure 6). Use wall
anchors and screws to secure the sensor.

Note: Avoid touching the mirror. Fingerprints may affect

detection coverage.
