Technically, there is no such thing as a false alarm – and yes, I can hear the protests from here! So why does your security alarm go off and there is no apparent reason for it?
Here are a few common reasons we have found over the years:
- Blowing curtains from open windows. This is a very common cause, especially during summer. There really is no way around this other than closing your windows.
- Pets such as cats and dogs. They either need to be outside when the alarm is set, or you could consider upgrading your sensors to “pet friendly” ones.
- Renovations can block a detector – it does happen frequently! Moving the sensor to a more ideal position is usually all that is required.
- Ants, geckos and other small bugs have been known to nest inside detectors which plays havoc with the wires. Regular use of surface spray around detectors, keypads and sirens (but not on the appliances) can help prevent this.
- Rats and mice. Rats and mice like to live in the roof of a house and quite often chew through the alarm wires. Possums also like to do this, but not nearly as much as rodents. Setting traps or bait to get rid of them is the only course of action, or relocation of a possum helps too.
- When I worked in a security control room many years ago, it was quite a common occurrence for thieves to set an alarm off and see how long it took for a customer or patrol company to respond, thereby giving the thief a window of opportunity. They also knew that by setting the alarm off several times the customer would assume it was a false alarm and request no action to be taken on that zone. The only way to combat this is vigilance – know what is happening in your area. Security cameras also help prevent this as thieves are less likely to want to get their face on CCTV several times.
I hope this helps explain why your alarm sometimes goes off for no reason – it can be a frustrating exercise to find the cause, but once found it’s an easy fix.
