How to Fix a Sensor Malfunction on the Honeywell PIR 5890

Summary: This article provides detailed troubleshooting steps for addressing sensor malfunctions on the Honeywell PIR 5890 motion detector. Common issues include low battery, poor signal strength, and incorrect placement, all of which may affect the sensor’s ability to detect motion.

Common Causes of Malfunctions

• Low Battery: The sensor may fail to detect motion accurately if the battery is running low or improperly installed.
• Poor Placement: Incorrect positioning or obstacles may block the sensor’s detection zone.
• Signal Interference: Large objects, walls, or electronics may disrupt communication between the sensor and the panel.

Step-by-Step Troubleshooting

1. Check and Replace the Battery:
   1. Open the sensor cover by pressing the latch or sliding it open.
   2. Inspect the battery for signs of wear or corrosion.
   3. Replace the battery with a new CR123A lithium battery, ensuring proper orientation.
   4. Close the sensor cover and test by walking through its detection zone.
2. Verify Placement:
   1. Ensure the sensor is installed at a height of 6.5 to 8 feet for optimal performance.
   2. Keep the sensor away from windows, heat sources, or air vents.
   3. Reposition the sensor to ensure its detection zone covers the desired area without obstructions.
3. Test Signal Strength:
   1. Open the Brinks Home app and locate the sensor’s signal strength under device details.
   2. If the signal strength is below 80%, consider relocating the sensor or using a signal repeater.
4. Check for Interference:
   1. Identify potential sources of interference, such as large appliances or metal objects.
   2. Move the sensor to a location with minimal interference.
5. Power Cycle the Sensor:
   1. Remove the sensor’s battery for 2 minutes.
   2. Reinsert the battery and allow the sensor to reconnect to the system.
6. Reset and Reconnect the Sensor:
   1. Remove the sensor from your system through the Brinks Home app or control panel interface.
   2. Follow the manufacturer’s instructions to reset the sensor to factory settings.
   3. Re-add the sensor to your Brinks Home system and test its functionality.
