1. Introduction
The PGST P92R-3 Smart Infrared Motion Sensor is a passive infrared (PIR) detector designed to enhance the security of your home or office. It detects movement by sensing changes in infrared radiation within its detection area. This sensor is compatible with various PGST home alarm systems, including models A103F, A105F, A107F, A108F, A109F, A01F, A02F, and A519W, providing reliable anti-theft protection.

3.2 Mounting the Sensor
The P92R-3 sensor is designed for wall mounting to optimize its detection capabilities.
- Choose a suitable location for installation, typically in a corner or on a wall where it can cover the desired area without obstruction. Avoid direct sunlight or heat sources.
- Use the provided screws and wall anchors to securely attach the installation bracket to the wall.
- Slide the sensor onto the mounted bracket until it clicks into place. Ensure it is firmly attached.

3.3 Pairing with PGST Alarm System
Refer to your specific PGST alarm system's manual (e.g., A103F, A105F, A107F, A108F, A109F, A01F, A02F, A519W) for detailed instructions on how to add new wireless sensors. Generally, the process involves:
- Accessing the 'Add Sensor' or 'Zone Settings' menu on your PGST alarm host.
- Activating the sensor (e.g., by triggering it or pressing a pairing button if available) to send a signal to the host.
- Confirming the sensor is successfully added to a zone on the alarm system.
4. Operating Instructions
4.1 Activating the Sensor
Once batteries are installed and the sensor is mounted, switch the power button on the back of the sensor to the 'ON' position. The sensor will typically perform a self-test and enter standby mode.
4.2 Motion Detection
When the alarm system is armed, the P92R-3 sensor will monitor its detection area for changes in infrared heat signatures. Upon detecting movement, it will transmit a signal to the connected PGST alarm host, triggering the alarm according to your system's settings.

4.3 Low Battery Notification
The sensor continuously monitors its battery level. When the battery is low, it will send a signal to the alarm host, which will then notify you through the alarm panel or associated mobile application. Replace batteries promptly to ensure uninterrupted security.

5. Maintenance
5.1 Battery Replacement
When a low battery alert is received, replace both the AA and Lithium Polymer batteries immediately. Use only recommended battery types. Follow the steps in Section 3.1 for battery installation.
5.2 Cleaning
Periodically clean the detection window with a soft, dry cloth to ensure optimal performance. Avoid using abrasive cleaners or solvents, as these can damage the sensor.
6. Troubleshooting
- Sensor not detecting motion:
- Check if the sensor is powered on.
- Ensure batteries are correctly installed and not depleted.
- Verify the detection window is clean and unobstructed.
- Confirm the sensor is within range of the alarm host.
- Check the alarm system's zone settings to ensure the sensor is active.
- False alarms:
- Ensure the sensor is not placed near heat sources (e.g., vents, direct sunlight) or moving objects (e.g., curtains near a window).
- Verify the mounting is secure and the sensor is not vibrating.
- Adjust the sensor's position if necessary to avoid pets or drafts.
- Sensor not connecting to alarm host:
- Ensure the sensor is powered on and batteries are good.
- Re-attempt the pairing process as described in your alarm system's manual.
- Check for any interference or distance issues between the sensor and the host.
