4. Enrollment:
To enroll the motion sensor, set your panel into programming mode
according to the panel manufacturer’s instruction. When prompted by the
panel, enter the 7 digit serial number printed on the sensor label. Make sure
the loop number is set to Loop 1.
Some panels can enroll your sensor by capturing the serial number
transmitted by your sensor. The sensor can be enrolled by triggering wireless
transmissions. Place the sensor into walk test mode by holding down the
sensor’s tamper switch while inserting the battery. The red LED will begin to
flash for 30 seconds. When the LED stops flashing, the sensor can be triggered
by waving your hand in front of the motion sensor. The sensor will transmit
every time motion is detected. Trigger the motion sensor as many times as
necessary until the panel recognizes the sensor’s serial number. Make sure
the loop number is set to Loop 1.

5. Mounting
Mount the motion sensor at 7.5 feet (2.3 meters)
above the floor. Press thecase release button to
separate the front and back sensor case. The back
case gives access toboth the flush mount and corner
mount screw knock outs. Remove the appropriate
knockouts and use the included screws tomount in
the desired mounting location. Itisrecommend to
ensure there is a tight seal around the knockouts to
prevent bugs from entering the sensor and causing
false alarms. Replace the front sensor cover tosnap
shut andscrew in the sensor case screws on the top
and bottom ofthe back sensor case. The WST-741
intrusion detection unit shall be installed in
accordance with the Standard for Installation and
Classification ofResidential Burglar Alarm Systems,
CAN/ULC-S310. The WST-741 isintended to be
installed in accordance with the Standard for
Installation andClassification ofResidential Burglar
Alarm Systems, UL1641.
6. Sensitivity Jumper Settings
For normal sensitivity motion detection leave the jumper inthe default
setting (on). Remove the jumper ifincreased sensitivity tomovement is
desired.
7. Walk Test Mode
Walk test mode can be used to test themotion sensor detection coverage
area. Toenter walk-test mode hold down the tamper button while inserting
the battery. The red LED will begin toflash indicating that the motion sensor
is warming up. After 30 seconds the LED nolonger flashes and the motion
sensor isready todetect motion. The LED will illuminate each time motion is
detected. Once the LED goes out, the sensor is ready to detect motion again.
Walk test mode ends after twenty motion detections or ifnomotion isseen
for one minute. It is recommended that the WST-741 PIR is tested monthly to
ensure proper function.
8. Operation
During normal operation, the LED will not turn on even ifmotion isdetected.
This is done tomaximize battery life.Furthermore, when motion isdetected
and a signal is transmitted to the panel, the sensor will not transmit again for
a period of three minutes. The WST-741 isanintrusion detection unit and
shall provide for connection into an alarm system in accordance with the
Standard for the Installation andClassification of Residential Burglar Alarm
Systems, CAN/ULC-S310.
9. Maintenance - Replacing the Battery
When the battery is low, a signal will be sent to the control panel.
To insert or replace the battery:
•Remove the front cover to expose the battery
•Remove the backplate using a bottom-to-top lifting motion.
•Remove the CR123A lithium battery. Note the correct orientation of the
battery as shown on the sensor cover plate.
Always match the plus (+) sign on the battery with the flat side of the
compartment and the minus (-) sign on the battery with the spring side.
•Replace the front cover.
WARNING: Failure to follow these warnings and instructions can lead to heat
generation, rupture, leakage, explosion, fire, or other injury, or damage. Do
not insert the battery into the compartment in the wrong direction. Always
replace the battery with the same or equivalent type (see Specifications on
page 1). Never recharge or disassemble the battery. Never place the battery
in fire or water. Always keep batteries away from small children. If batteries
are swallowed, promptly see a doctor.
•Always dispose and/or recycle used batteries in accordance with the
hazardous waste recovery and recycling regulations for your location. Your
city, state, or country may also require you to comply with additional
handling, recycling, and disposal requirements.
10.`Environmental and Other Useful Information
•While the PIR is a highly reliable intrusion detection device, it does not guarantee against
burglary. Any intrusion device is subject to a “failure to warn” for a variety of reasons.
Consider the following when installing and setting up the PIR:
•This PIR has built-in protection to keep bugs from getting into the sensor area and causing
false alarms. Note that this protection does not prevent insects from crawling across the
lens of the PIR, which could trigger the PIR.
•Infrared energy can be reflected off any glossy surfaces such as mirrors, windows, floors,
or counter tops with glossy finish, and slick-finished concrete. Some surfaces reflect less
than others (e.g. the PIR can see a change in infrared energy off of reflective surfaces even
if the heat or cold source is not within the PIR detection pattern).
•Windows reflect infrared energy. They also allow sunlight or light from other sources (e.g.,
cars) to pass through to the PIR. The PIR can detect these changes in infrared energy. For
example, if sunlight passing through a window shines onto a hardwood floor and the

change in infrared energy is quick enough, the PIR can trigger an alarm. The same applies
if the PIR area includes a window, even though the pattern of protection cannot “see”
through glass. Lights from a passing car can also pass through the window at night and
shine directly into the PIR’s lens.
•Heating and air conditioning ducts are also important because if they blow air onto an
object within the field of the PIR’s view, the temperature of that object could change
quickly enough for the PIR to “see” a change in infrared energy. PIR’s cannot see air
current, only the change in temperature of a physical object.
•The PIR senses change in temperature. However, as the ambient temperature of the
protected area approaches the temperature range of 95° to 120° F, the detection
performance of the PIR decreases.
•Ensure that the area you wish the PIR to cover is free of obstructions (for example,
curtains, screens, plants, and so on.) that may block the pattern of coverage.
•Anything that can sway or move due to air current can cause a change in infrared energy
within the fields of view. Drafts from doors or windows can cause this to happen. Plants,
balloons, curtains, and hanging baskets should never be left in the PIR’s field of view.
•Do not mount the PIR on a surface that allows for any vibration. Vibrations not only cause
the PIR to move a little, but it also causes the fields of view in a room to move with
respect the PIR. A little vibration can cause havoc with the PIR’s field of view, thus the PIR
may see a change in energy and trigger the alarm.
•An installation often requires that the PIR is aimed at the door. The PIR may detect door
movement before the door contact can initiate an entry delay, causing the alarm to
trigger. If you install the PIR facing a door, then while programming the PIR, choose an
appropriate sensor/zone type.
•The PIR ONLY detects intrusion within the pattern of coverage.
•The PIR does not provide volumetric area protection.
•The PIR creates multiple beams of protection. Intrusion can only be detected in
unobstructed areas covered by those beams.
•The PIR cannot detect motion or intrusion that occurs behind walls, ceilings, floors, closed
doors, partitions, glass doors, or windows.
•Tampering with, masking, painting, or spraying of any material on the PIR lens or any part
of the optical system can impair detection ability.
•The PIR, like other electrical devices, are subject to component failure. Even though the
PIR is designed to last as long as 10 years, the electronic components are subject to
failure.
