A malfunction (or offline) condition occurs when the control panel has not received a signal from a specified device in the past 24 hours.
Check for a low battery signal in the history. If a low battery message has been located in the history on your Frontpoint App/website, or you notice a text/email confirming a low battery signal, change the batteries.
The Long Range Door and Window Sensor uses x1 CR123A battery that will last 3-5 years.
To open the sensor, press in on the plastic above the protrusion on one of the two short ends to open the cover and reveal the battery.
Pop the CR123A battery out of the compartment to replace.
Insert the new battery into the compartment. Please take note of the + and - symbols inside of the compartment.
Once the battery is replaced, replace the front cover back on the face of the sensor.
