This signal is a non-alarm event that indicates that a sensor circuit is not complete. A Sensor Trouble renders the particular circuit inoperative and no longer able to provide security as designed.
An incomplete circuit maybe caused by a fault with cabling, the sensor or the alarm system’s main board.. A Sensor Trouble should be inspected & the cause of the trouble rectified. The circuit will mainly be incomplete because it’s open or activated and not restored – however sometimes it’s broken. A technican should be called to investigate the trouble.
