Product Summary
A motion sensor (passive-infrared or PIR) detects move-
ment 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.
This wireless motion sensor includes the following features:

Field-selectable coverage area; 33 or 50 feet

Field-selectable sensitivity modes; 2-pulse or 4-pulse

135-second transmitter lockout time after an alarm that
helps extend battery life

Cover-activated tamper

Supervisory signal transmitted every 64 minutes to the
control panel

Sensor low battery reports (trouble) to the control panel
Included with the sensor is a thin cardboard undercrawl
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 loca-
tion may help overcome adverse wireless conditions.

Mount the sensor permanently on a flat wall or in a cor-
ner. Do not set it on a shelf.

For installations without pets, the required mounting
height is 7 1/2 feet.

Mount the motion sensor on an insulated, outside wall
facing in.

Mount the motion sensor on a rigid surface which is
free from vibrations.

Position the sensor so it faces a solid reference point,
like a wall.

Do not aim the sensor at windows, fireplaces, air condi-
tioners, heaters/heating vents, or place it in direct sun-
light.

Position the sensor to protect an area where intruders
are most likely to walk
across
the detection pattern (see
Figure 1).
Figure 1. Overhead View of Detection Pattern

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 transmit-
ter range should be verified for each installation.

Windows should be closed in any area which has an
armed motion sensor.

The cardboard undercrawl mask installed at the factory
(see Figure 2) blocks coverage within 5 feet of the sen-
sor.

1RWH
The cardboard undercrawl mask should remain
installed when sensor jumper J1 is set to the BI posi-
tion. See the section “Setting the Sensor Coverage
Area and Sensitivity” for complete information on sen-
sor jumper settings.

Mounting the Sensor

For installations where pets are present, mount the sen-
sor upside down about 3.5 feet above the floor (see Fig-
ure 3). Leave the factory-installed undercrawl mask in
place to block any detection pattern directed at the ceil-
ing.

Setting the Sensor Coverage Area and Sensitivity
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 cov-
erage 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 cover-
age.
1RWH
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 undercrawl mask
installed.
& $87,2 1
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 7. Sensitivity Mode and Coverage Area Jumper
Settings
Walk Testing
Walk testing should be done to determine the actual cover-
age area of the sensor. The edge of the coverage pattern is
determined by the first LED flash. This may change slightly
depending on the sensitivity setting. Walk test the unit from
both directions to determine the pattern boundaries.
1.
Remove the sensor cover to activate the tamper switch,
then reattach it to activate the 2-minute walk test mode.
2.
Walk across the coverage pattern to determine the cov-
erage area, indicated by LED activation.
After 2 minutes, the walk test mode and the LED will no
longer activate when motion is detected.
1RWH
Excessive use of the walk test mode may reduce bat-
tery life. Use only for initial setup and maintenance
testing.
1RWH
In normal operation mode, the sensor only transmits
an alarm signal 135 seconds after the previous alarm.
This reduces unnecessary RF transmissions in high
traffic areas, thereby extending battery life.
Environment Testing
Activate the walk test mode, then turn on all heating or air
conditioning sources which would normally be active dur-
ing the protection period. Stand away from the sensor and
outside the coverage pattern and watch for alarms.
Installing Masks
After determining the full coverage area and performing the
environment test, you may need or want to mask (block)
certain parts of the coverage.
Self-Adhesive Masks
Block the appropriate mirror sections with these masks.
Figure 8 shows an example of where to apply the masks and
the resulting coverage area.
& $87,2 1
To avoid damaging the mirror, do not remove masks
using a sharp tool. If necessary, remove masks by
carefully peeling them off with your fingers.

Programming
Plastic Masks
Install these masks for half coverage or narrow coverage
applications (see Figure 9).
Figure 9. Installing Plastic Masks
1RWH
After installing masks, always conduct a walk test and
environment test to verify the coverage area is correct
for the application.
Programming
The following describes the basic steps for adding (learn-
ing) the sensor into panel memory. Refer to the specific
panel installation instructions for complete programming
information.
1.
Put the panel into program mode.
2.
Advance to the learn sensors menu.
3.
Enter the appropriate sensor group and desired sensor
number.
4.
When the panel prompts you to trip the sensor, activate
the sensor tamper switch by removing the sensor cover.
5.
Reattach the sensor cover.
6.
Exit from program mode.
Final Testing
Final testing should be done to verify radio signal integrity
and confirm control panel programming and response. The
actual transmitter range can be determined by performing a
sensor test as described below. Refer to the specific panel
installation instructions for complete sensor testing infor-
mation.
1.
After the sensor has been mounted, remove the sensor
cover to trip the tamper switch and activate the walk
test mode.
2.
Replace the sensor cover.
3.
Place the control panel in test mode.
4.
Move across the detection pattern until the sensor LED
turns on, then STOP your motion.
5.
Listen for the appropriate system response. If the sys-
tem does not respond, proceed to the

Troubleshoot-
ing

section.
Maintenance
At least once a year, the sensor should be tested to verify
correct operation. The end user should be instructed to put
the sensor in walk test mode and walk through the far end of
the coverage pattern to verify proper detection.
Replacing Batteries
When battery replacement is necessary, observe proper
polarity (positive +, negative -) when installing the new bat-
teries, or the sensor may be damaged.
Use only exact replacement 3-volt lithium batteries
(CR123A).
& $87,2 1
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.
1.
Remove the sensor cover (see Figures 4 and 5) and set
it aside.
2.
Remove the transmitter (upper) circuit board battery
(see Figure 10).

site side of components) and install a new one, observ-
ing polarity (marked on the circuit board).
6.
Re-install the PIR circuit board into the sensor plastic.
7.
Re-install the transmitter circuit board onto the PIR cir-
cuit board.
8.
Install a new battery in the transmitter circuit board,
observing polarity (marked in battery bucket).
After replacing batteries, wait at least 3 minutes before acti-
vating the walk test mode.
Lithium Battery Disposal
Lithium batteries that are no longer usable are considered
hazardous waste. Be sure to properly dispose of the old bat-
teries. Contact your local city government for hazardous
waste disposal laws.
Troubleshooting
Use the following guidelines if the system does not respond
correctly when the sensor is activated.

Check programming and re-program sensor into panel
if necessary.

Move the sensor to another location and test for correct
response.

Test a known good sensor at the same location.

If the system does not respond, avoid mounting a sen-
sor at that location.

If the replacement sensor functions, return the problem
sensor for repair or replacement.
