GC2/GC2e — Sensor Malfunction

Your alarm panel performs a “roll call” every hour, sending a signal to all connected sensors to confirm they’re working properly.
 If a sensor fails to reply, the panel will display a Malfunction/Failure message, and you may also see an alert in the Alarm.com app.

Common Causes of Sensor Malfunction

  • Dead Battery – The sensor battery may need replacement.

  • Distance from Panel – If a sensor is more than ~100 ft away, communication may fail.

  • Radio Frequency (RF) Interference – Other devices or materials may block signals, including:

    • Wi-Fi routers, cordless phones, game controllers, video doorbells

    • Large appliances (fridge, TV), metal studs, reinforced plaster, or concrete walls

  1. Replace the Battery

    • Ensure the cover is securely closed after replacement. A loose cover may cause a tamper error.

    • Verify the arrows on sensor parts are aligned and no more than ¼ inch apart.

  2. Run a Sensor Test

    • This will trigger another roll call.

  3. Check for Interference

    • Look for new electronics or large objects placed near the sensor or panel.

  4. Replace the Sensor if Needed

    • If issues persist, the sensor itself may be defective.
