Why do security systems give false alarms?

While intruder alarms can act as a fantastic deterrent to burglars, if they are constantly giving false alarms, this effectiveness is significantly depleted. Where first an alarm going off grabs attention and causes people to react to the emergency, if this is a frequent occurrence it will not only irritate you and those around you, but cause everyone within hearing distance to know that your alarm is not necessarily a sign of intrusion. But why do security systems provide false alarms?

Poor maintenance:
Every security system needs to undergo regular maintenance. Depending on the system you have chosen, this could mean an annual or even bi-yearly check. This ensures everything is functioning as it should and can identify reasons for false alarms and prevent them happening again. Failure to do this inevitably leads to decline in the quality of your security system – and can create lots of problems. Key indicators that your security system is in need of a check include the alarm going off every time there is any form of power failure, and outdated batteries. In general, an alarm system’s battery backup will only last for approximately five years and the batteries in the wireless detectors last around 2 years – so there is no time to waste in replacing them and taking the opportunity to undergo a complete maintenance check, identifying other issues before they become more serious and long-lasting faults.

Improper installation:
It is worth considering whether the system you have fitted is suited to your property if you constantly find the security system provides false alarms. There are many factors which should be taken into consideration pre-install, which is why it is often preferable to contact a security professional and ask for guidance prior to settling on a type of system. Everything from the temperature of the room, to the risk drafts causing movement, and even whether you have pets which might trigger an alarm system’s PIR sensors must all be noted and dealt with before you end up paying the price of poor installation later on. Always ensure you have an approved security engineer on-hand and if you have bought security kit yourself, be sure to get it installed by someone with the skills to get it right first time.

Keyholder Error:
Ensure that all keyholders setting and unsetting your intruder alarm are fully trained in its operation such as entry route, codes and locations of detectors. The key factor is to ensure burglars have no reason to believe your alarm system will be ignored if it is set off, and that your alarm is always active when you leave the property so when neighbours hear your alarm sound they are more likely to contact the Police.

If you choose to install an alarm, it’s important to look after it – as poor maintenance, bad installation and failure to prevent false alarms will all weaken its effectiveness and cause this potentially valuable tech to falter.

Always use an approved installer to ensure a quality installation.
