With wired alarm systems, the backup battery will need to be replaced when it is unable to hold its charge. This is generally once every 5 years. The alarm will let you know when you hear a beeping sound coming from the control panel.

We provide backup battery replacement for customers at a flat fee of $250.

With wireless systems, you would have to change the battery of the sensors every few years. The sensor will generally let you know when battery runs low. We can also assist you with this, but its generally an easy DIY change. Batteries are generally CR123A which you can buy from your local hardware store
