Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the DSC PG9303 Wireless PowerG Door/Window Contact. Please read this manual thoroughly before attempting to install or operate the device to ensure proper functionality and safety.
Product Overview
The DSC PG9303 is a wireless contact sensor designed to monitor the open/closed status of doors and windows. It consists of two main components: a sensor unit and a magnet.
Components
- Sensor Unit: The larger component, typically mounted on the door or window frame. It contains the internal electronics and battery.
- Magnet: The smaller component, mounted on the moving part of the door or window.

Setup and Installation
1. Battery Installation
- Carefully open the sensor unit casing.
- Insert a CR2450 battery, ensuring correct polarity (+/-).
- Close the sensor unit casing securely.
- Important: If the device does not power on or pair, try removing and reinserting the battery to initiate pairing mode, as suggested by user experience.
2. Mounting Location
- Identify a suitable location on your door or window frame for the sensor unit and the corresponding door/window for the magnet.
- Ensure the mounting surfaces are clean, dry, and smooth for optimal adhesive performance.
- The sensor unit should be mounted on the stationary part (frame), and the magnet on the moving part (door/window).
- For proper operation, the magnet must be in close proximity to the sensor unit when the door or window is closed. A spacing gap larger than half an inch (approximately 1.27 cm) may prevent proper detection.
3. Mounting the Device
- Peel the protective backing from the adhesive pads on both the sensor unit and the magnet.
- Firmly press the sensor unit onto the chosen location on the frame.
- Align the magnet with the sensor unit and firmly press it onto the door or window. Ensure the alignment marks (if present) on both components face each other.
- Hold each component in place for at least 30 seconds to ensure strong adhesion.
4. Pairing with Your Alarm System
Refer to your specific alarm system's user manual for detailed instructions on how to add a new wireless PowerG device. Generally, the process involves:
- Accessing the programming menu on your alarm system's keypad.
- Selecting the option to add a new wireless zone or device.
- Activating the PG9303 sensor (e.g., by opening and closing the door/window it's installed on, or by removing and reinserting the battery if it's a new installation). The alarm system should detect the sensor.
- Assigning the sensor to a specific zone and configuring its settings (e.g., zone type, chime).
- Testing the sensor to confirm successful pairing and operation.
Operating Instructions
Basic Operation
The DSC PG9303 operates by detecting the presence or absence of its magnet. When the magnet is in close proximity to the sensor unit (door/window closed), the sensor is in a "closed" state. When the magnet moves away from the sensor unit (door/window opened), the sensor transitions to an "open" state, triggering a signal to your connected alarm system.
- Closed State: Door or window is shut, magnet is aligned with the sensor.
- Open State: Door or window is opened, magnet is separated from the sensor, sending a signal to the alarm panel.
The response of your alarm system (e.g., chime, alarm activation) depends on the zone programming configured during installation.
Maintenance
Battery Replacement
The PG9303 sensor is powered by a CR2450 lithium coin cell battery. When the battery level is low, your alarm system will typically indicate a low battery condition for the respective zone. To replace the battery:
- Disarm your alarm system to prevent false alarms during maintenance.
- Carefully open the sensor unit casing.
- Remove the old CR2450 battery.
- Insert a new CR2450 battery, observing correct polarity.
- Close the sensor unit casing securely.
- Test the sensor by opening and closing the door/window to ensure it communicates with the alarm system.
- Dispose of old batteries according to local regulations.
Cleaning
Clean the exterior of the sensor and magnet periodically with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the device.
Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Sensor not pairing with alarm system. |
|
| Sensor not detecting open/close events. |
|
| False alarms or intermittent signals. |
