5 Causes of False Intruder Alarms – And How to Solve Them

Here are some of the top causes and how to solve them…

According to Which? magazine, 43% of alarm owners have experienced a false alarm. So, what are some of the major causes for false intruder alarms?

Human error

Human error counts for a huge proportion of false alarms. This is usually due to the homeowner setting off the alarm by mistake, then forgetting the code or taking too long to enter the code. False alarms are also often caused by guests in your home, including cleaners, tradesmen or babysitters, who have not been informed about how to turn off the alarm.

Pets

According to the same survey by Which?, sensors picking up on the indoor antics of pets accounted for 21% of false burglar alarms.

Insects

And it doesn’t just stop with pets – insect life can trigger your alarm too. For example, spiders creating a web over your sensor can cause a false alarm.

Poor installation

Sensors react to changes in motion and heat, so it’s important for them to be installed in suitable positions. Generally speaking, you should avoid installing sensors at points that may experience dramatic changes in temperature. This includes above radiators or stoves, or next to showers where steam can rise. A professional intruder alarm installation will ensure that your sensors are installed at the correct positions in your property to avoid false alarms.

System issues

The most common system errors that can cause a false alarm include faulty wiring or low batteries. Usually, your intruder alarm will warn you as the batteries start to get low, so you can replace them.

With these factors in mind, here are some steps you can take to avoid false alarms…

• Ensure everyone understands the system – The passcode you use needs to be something you can remember. Any authorised person who could potentially set off the alarm when you’re not around should also know the code and how to use the alarm system.
• Pet-proof alarms – Certain motion sensors are programmed to ignore movement caused by pets under 35kg. If your pet is a larger size, then a smart alarm could be the best option.
• Maintenance – Every so often you’ll need to dust your alarm, which can also help to remove any insects that might trigger it. You should also ensure the batteries are regularly changed.
• Careful positioning – A professional alarm installation will ensure your sensors are positioned in just the right spot.
• Windows and doors – You should also always ensure windows and doors are locked tight before setting the alarm, as this avoids the wind triggering the alarm – or blowing curtains which could also trigger a motion sensor.
• Regular inspections – Servicing your alarm at least once a year will ensure it’s up to standard.

Keeping your home safe is of the utmost importance. Ultimately, the best way to do so and avoid false alarms, is to invest in a high-quality intruder alarm system. That’s where Selectron comes in.
