Note: The sensor has a LED that flashes to show when the sensor has triggered and transmitted to the main unit.
Step 4 - When testing is complete, unplug the AC adapter, then plug the AC adapter back in and reinstall batteries. This returns the Control Center to standard operation mode.
Note: The Control Center will automatically return to standard operation mode after 5 hours.
Low Battery Indicator
The Control Center continuously monitors all the Sensors. If the Control Center does not receive a signal from any Sensor it will begin rapidly flashing the Zone LED indicator . This indicates one or more Sensors in the Zone may have low battery power and are unable to transmit a signal the necessary distance. If all batteries and/or Sensors are installed at the same time into a Zone, it is recommended to replace the batteries in all Sensors in the Zone.
However, you can check the Garage Door Sensor status independently by placing the Control Center in Test mode (see Testing a Sensor on page 9) and trigger the Sensor separately (i.e. open garage door). If the Sensor does not trigger an alert then replace the battery with a new one. Additionally, the red LED on the Sensor will flash when the Sensor is triggered.
