battery compartment

I don't have an account, but the previous homeowner had an AT&T security system. - it is chirping like crazy and I can't figure out where the battery compartment is.  Any advice on how to find the battery compartment?

@oliviamia99   Hello. You will need to unplug it AND remove the batteries for it to stop chirping.... I am not sure if you have a DLC 100 or DLC 200 but the battery is located under the screw on the front of the units.
