IQ Panel 2 - How to Fix a Sensor Malfunction Error

Every hour, your alarm system sends a signal to all of your sensors to ensure functionality and proper reporting, which is called a "roll call". If a sensor fails to send a response signal, a "Failure" alert will be sent to your control panel and “Malfunction” will display on the Brinks Home™ Mobile App.

Common Reasons a Sensor Will Go into "Failure" or "Malfunction"

  1. The battery in the sensor is dead.
  2. The sensor is too far from the control panel. If the sensor exceeds 100 ft, then a malfunction may occur.
  3. There is something causing Radio Frequency (RF) interference near that sensor or near the control panel. Common wireless devices that cause interference include the following:
    Routers, telephones, gaming controllers, doorbells, large metallic objects such as refrigerators or large TVs, plaster walls with metal fiber, metal studs in the wall, or interior concrete walls

Recommendations

  1. Change the sensor battery. Note: If you change the battery, be sure to reseat the cover. If the cover is not properly aligned and snug it will create a tamper error. Additionally, check to make sure the arrows on the sensors are lined up and there is no more than ¼ inch between the two when mounting.
  2. Perform a sensor test to attempt another "roll call", using the instructions below.
  3. Survey the area for recent changes, such as new nearby electronics which may be causing interference.
    • If the panel is on a portable stand, you may try placing the panel in a more central location.
    • If you cannot move your panel, you may need to consider a repeater to reach sensors that are out of range.
  4. If the problem persists, you may need to replace the sensor as it is defective.
