PG9872/PG8872/PG4872 Overview
The PGx872 is a smart wireless ceiling PIR presence/security detector
(selected mode) that creates a 36 coverage area to detect the move-
ment of intruders in indoor areas.
The detector has the following features:
l Presence detection mode - active 15 minutes after installation
(power-up) and then only when the panel is in Disarm mode.
l Security detection mode - operates as a normal motion security
l Built-in link quality indicators eliminate the need for the installer to
physically approach the control panel and reduce installation time.
l The device supports temperature and light level reports to com-
patible alarm systems that support temperature and light sensors.
l Tamper protection.
l PowerG two-way Frequency Hopping Spread Spectrum FHSS-
TDMA technology.
l The Advanced True Motion Recognition™ algorithm (patented) dis-
tinguishes between the true motion of an intruder and any other dis-
turbances which may cause false alarms.
NOTE: For UL installations, the detector is for use with UL listed con-
trol units only.

Inserting or replacing the battery
To insert the battery, complete the following steps.
1. To separate the detector from the mounting bracket, rotate the
bracket anticlockwise and pull it from the detector.
2. Insert the battery while observing polarity.
NOTE: If the battery is already installed, pull the isolation strip
that protrudes from the back of the detector.
3. Align the bracket tabs with the detector slots and rotate the detector
clockwise to verify that it is securely attached.
Figure 2. Removing the bracket
NOTE: If a screw is used to secure the detector to the bracket (see
Figure 3), open the screw cover, and remove the screw. To separate
the detector from the mounting bracket, ensure the screw cover is
fully open or fully closed, and rotate the detector anticlockwise.
Replace the battery ensuring polarity is observed. Replace the
detector and secure to the bracket with the screw.
NOTE: It is recommended to wait about 1 minute after battery
removal before inserting the new battery.
Caution! Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the manufacturer's instructions
and according to local rules and regulations.
Refer to the panel installation manual for the enrollment procedure.
A general description of the procedure is provided in the following
flow chart:
Step Procedure
1 See the installation manual for the alarm system that the
device is being enrolled on to ensure that the proper steps
are used.
2 Enter the Device Enrollment option through the specified
method and select the appropriate option to add the new
3 Enrollthe device by either inserting the battery to power on
the device until the enrollment is detected, or by entering the
Device ID.
Pull the enrollment tab or insert the battery to power up the
device and begin the auto-enrollment process.
NOTE: You can also enter ID:XXX-XXXX (the number of
the device that is printed on the label), if the device does not
automatically enroll.
4 Select the desired Zone Number.
5 Configure any device parameters that are required.
6 Mount and test the detector. See Walk testing / local dia-
gnostic testing for information on testing the device. In addi-
tion, see the alarm system installation manual that the device
is enrolled on for other test procedures that are required.
NOTE: If the detector is already enrolled, you can configure the
detector parameters by programming the system. See the alarm system
installation manual for more information about device parameters.
NOTE: When enrolling the PGx972 detector to wireless panels
(WP80XX) with version 19.4 or lower, the detector will be enrolled as
motion detector, ID 120-xxxx, and labelled Motion Sens’ in the panel.
Installation tips
Use the following as a guide for locating a suitable mounting location.
Figure 3. General guidelines
1. Keep away from heat sources.
2. Do not expose to air drafts.
3. Do not install outdoors.
4. Avoid direct sunshine.
5. Do not install near high voltage electrical lines.
6. Do not install behind partitions.
7. Mount on a solid stable surface.
WARNING! Do not partially or completely obscure the detectors
field of view.
WARNING! To comply with FCC and ISED Canada RF exposure com-
pliance requirements, the PIR detector should be located at a distance
of at least 20 cm from all persons during normal operation. The anten-
nas used for this product must not be co- located or operated in con-
junction with any other antenna or transmitter.
NOTE: The PGx872 Wireless ceiling PIR presence/security detector
shall be installed and used within an environment that provides the
pollution degree max 2 and overvoltages category II in NON
HAZARDOUS LOCATIONS. The equipment is designed to be
installed only by qualified service persons.
NOTE: PGx872 shall be installed in accordance with the Standard for
Installation and Classification of Residential Burglar Alarm Systems,
UL 1641.
Walk testing / local diagnostic testing
Before permanently mounting any wireless device, temporarily mount
the device and perform a walk test. Perform a walk test of the cov-
erage area at least once a week to ensure that the detector is working
After inserting the battery or closing the bracket, the detector will auto-
matically enter a stability period where the LED flashes RED for 90
seconds. Walk test the coverage area; the LED lights red each time
your motion is detected followed by 3 LED blinks. The color of the 3
LED blinks indicate the received signal strength. In walk-test mode,
regardless of the LED Selection status, the LED lights upon every
motion detection. After 15 minutes the detector automatically enters
normal mode.
The following table indicates the received signal strength.
LED Response Signal Strength
3 green LED blinks STRONG
3 orange LED blinks GOOD
3 red LED blinks POOR
No blinks No communication
IMPORTANT! Only GOOD or STRONG signal strengths are accept-
able. If you receive a POOR signal from the device, re-locate it and
re-test until a GOOD or STRONG signal is received.
NOTE: For UL/ULC installations, only STRONG signal levels are
acceptable. After installation verify the product functionality in con-
junction with the compatible devices HSM2HOST9, HS2LCDRF(P) 9,
HS2ICNRF(P)9, PG9920, WS900-19, and WS900-29.
NOTE: For detailed Placement instructions refer to the control panel
reference manual.
Walk-test the coverage area by walking across the far end of the cov-
erage pattern in both directions. The red LED lights each time your
motion is detected followed by a steady LED signal strength indication.
Mounting the device
1. Mark and drill two holes in the mounting surface. If you install
tamper protection on the detector, mark and drill one hole for the
tamper protection and one hole for one of the other available slots.
2. Fasten the bracket to the mounting surface with the two screws.
3. Align the bracket tabs with the detector slots and rotate the detector
clockwise. Verify that it is securely attached.
4. Fasten the detector to the bracket with the screw.
