How To Replace Batteries On Your Alarm Sensors

Your wireless alarm sensors utilize small batteries to power them. This modern design is great, so you don't have wires running all over your home or business. However, batteries do eventually die.

You have two options when your sensor reports a low battery:

1. Have an Epic Alarm technician visit you
Our customer success team can be reached by email or by phone to schedule a service technician to come out and replace them. There is a charge for a tech to come out. If you have EpicCare warranty coverage in effect, all charges will be waived.


2. Replace them yourself
Most sensors have batteries that can be replaced by you.  Please call Epic Alarm before replacing sensor batteries yourself, so we can put your account on test.  

The following is a list of our most common equipment, followed by the battery type and quantities and the replacement instructions.
