GC2 Panel—Sensor Malfunction

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 signal will be sent to your control panel and you'll see an alert or Malfunction in the Brinks Home™ App.

Common reasons a sensor will go into failure/malfunction are:

1. The battery in the sensor is dead.


2. The sensor is too far from the control panel. If the sensor exceeds 100 feet, 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.

Sensor Test for a GC2 GoControl Panel

1. Press Security, then Menu.
   


2. Press Toolbox, then enter the master code.
   


3. Press System Test and the panel enters test mode.
   

4. Walk to and trigger each sensor. For door/window sensors, open and close each door and each window. To test motion detectors, walk in front of the motion detector's field of view.

5. The panel will beep and show signal strength. If all sensors test successfully, press OK to continue to the next step.

   



6. Now, test the LED lights connected to your panel's Home button by pressing each of the numbered test modes showing on screen.
   


7. If the home button works correctly, press Yes, then press the down arrow to continue to the next step.
   


8. Test the Emergency button by pressing each test, then press No or Yes.





9. Press Sounder Audio Test, then press No or Yes if internal speaker sounds.
   


10. If all tests are successful, press OK then Back to exit.
