This article gives you four quick steps to clear the trouble light on your DSC alarm.

The trouble light on your DSC alarm was designed to turn on when the system detects trouble. The trouble could be a shorted-out wire or a low sensor battery.

Before we start, your keypad may look like one of the three keypads in the picture below. The following guide still applies, no matter which keypad you have.

Instructions to Clear the Trouble Light on Your DSC Alarm:

Although you don't have to do the steps in order, we suggest you silence the beeping first so you can troubleshoot without all of the noise.
