How to Reset a DSC Alarm After the Power Has Been Off

A DSC alarm system should run off of battery power for several hours during a power outage, but if you have a longer period of downtime, the batteries can be drained. When that happens, you will need to reset the sensors using the keypad on the control unit.

Step 1

Open the access door on the unit.

Step 2

Press and hold the "RESET" key for 2 seconds.

Step 3

Press the buttons "*72" if the alarm does not reset after pressing the RESET button.

Step 4

Check the sensors if it still does not turn off. It means one of the sensors is detecting an alarm condition, such as a glass break or activated smoke detector.
