How to Fix a Sensor Malfunction on the Honeywell Glass Break 5853

Summary: This article provides troubleshooting steps for resolving sensor malfunctions on the Honeywell Glass Break 5853. Issues may include low battery, poor signal strength, or incorrect sensitivity settings.

Common Causes of Malfunctions

• Low Battery: The sensor may not function properly if the battery is depleted or incorrectly installed.
• Signal Interference: Walls, appliances, or large metal objects can disrupt communication between the sensor and the panel.
• Incorrect Sensitivity Settings: The sensor’s sensitivity may be set too high or too low, causing false alarms or failure to detect glass breaking.

Step-by-Step Troubleshooting

1. Check and Replace the Battery:
   1. Remove the sensor cover by pressing the latch on the side.
   2. Inspect the battery for signs of damage or corrosion.
   3. Replace the battery with a fresh CR123A 3-volt lithium battery, ensuring proper orientation.
   4. Replace the cover and test the sensor by simulating a glass break sound.
2. Test Sensitivity Settings:
   1. Locate the sensitivity switch on the sensor's circuit board.
   2. Adjust the sensitivity to an appropriate level based on your environment:
      • High sensitivity for large open areas.
      • Low sensitivity for smaller, cluttered spaces.
   3. Test the sensor by tapping a glass surface or playing a glass break sound.
3. Verify Placement:
   1. Ensure the sensor is placed within 25 feet of the glass surface it is monitoring.
   2. Keep the sensor away from large electronic devices that may cause interference.
   3. Reposition the sensor if necessary to maintain line-of-sight with the glass surface.
4. Test Signal Strength:
   1. Open the Brinks Home app and navigate to the sensor’s details page.
   2. Check the signal strength reading. If it is below 80%, consider relocating the panel or using a signal repeater.
5. Power Cycle the Panel:
   1. Power down your control panel and restart it after 2 minutes.
   2. Test the sensor again to verify functionality.
6. Reset the Sensor:
   1. Remove the sensor from your panel through the Brinks Home app or your control panel interface.
   2. Follow the pairing instructions to re-add the sensor to your system.
