Common reasons for false alarms from home security systems
There are several reasons why your house alarm could keep going off. They include:
You've left a window (or door) open – It might sound obvious, but often house alarms are triggered by windows being left open. Wind then moves the curtains or other items in the room and that can set off your house alarm
A faulty sensor – A common cause of house alarms going off is a fault with the alarm's sensors. Causes for this include dust or debris in or on the sensor, or age; if the sensor is old it might need to be replaced
Dodgy wiring – Issues with the wiring of a wired alarm system are another common cause for triggering the alarm. If any of the wiring or cables that connect your alarm system are loose, it can cause your alarm to go off
Dead batteries – If your home security system uses batteries then they could be the culprit. When batteries need changing that can often lead to false alarms, as well as causing issues with arming or disarming the system
A fault in the control panel – The control panel, as you might have guessed from the name, controls your house alarm system. A fault in the control panel can quickly result in the alarm going off unnecessarily
A faulty burglar alarm – If you, or a qualified electrician, have checked all of the above and your house alarm is still going off, it could be a faulty alarm system. This is more likely with old house alarm systems, so you may need to upgrade your system
