False Alarms & Failing Batteries
Sitting on a warm summer day, contemplating where I'm going to build my BBQ and all I can hear is the distant sound of an alarm going off...
We all get the odd false alarm as there is never going to be a 100% reliable alarm, but summer seems to bring out the worse in this technology. I always thought it was because I'd ventured out and just happened to hear it, but over the recent couple of months of great weather we have seen a spike in systems randomly going off due to failing batteries.
In particular, wired systems that have a large sealed lead acid battery are susceptible when the weather warms up. They can hang on for years between services until eventually they start to lose their ability to hold a charge. The smarter alarm panels see this and pop up with a message saying "Battery Fault" or a warning symbol of some kind. But other just randomly go off without reason and drive customers up the wall.
The only way to combat this is have your system maintained on a regular basis and keep a note of when batteries were last changed. Almost all alarm specialists will write the date of battery replacement on the battery itself. So you know exactly how long its been in service.
We have even seen some batteries that have been in service so long they have deformed and cracked, leaking acid over the rest of the alarm and damaging it - but regular servicing preventst this.
So if your alarm is doing strange things or you've moved into a property with an alarm but don't know how it works - book a service and start using it.
After all its there to protect you not drive you up the wall.
