Ater enduring a week of complains from the wife decided to check out why one of the light indicators in the anti-burglar alarm control panel is lighted up day and night, even when all the doors and windows in the house are closed.
After checking around the whole house noticed that a magnetic sensor at a trap door has dislodged itself from its original station in the wooden door frame although the door is closed. Hence the separation between the magnetic sensors in the door frame and its counterpart in the door panel has triggered the ant-burglar alarm system to light up the associated indicators continuously.
The problem is resolved after re-attaching the sensor to the wooden door frame with heavy duty adhesive. With the two magnetic sensors properly secured and aligned with one another in position the affected indicator light automatically shut down by itself.
