Jason,

As others have said, the battery is a definite possibility.

But a stuck key is also a possibility and easy to diagnose. If one button is stuck, pressing that button won't cause the
problem. So try each button and if one *doesn't* make it beep, you've probably found your culprit.

The battery is in the control panel. Typically it's quite large as it
has to power the whole alarm system for hours. What makes you think
it's the keypad? If one key is intermittent, or similar, thenI'd say
its' the pad. If it's acting screwey, could be the controller, loose
connection, pad, etc.

My only reason for thinking that it's just the keypad is that the
incessant beep is coming from the keypad itself, not the siren. I
checked the connection and it seemed OK, so the only other things I
could come up with is (a) something on the circuit board, like a loose
wire, crossing paths, or (b) possibly a key is stuck and gives this
alarm when you press 2 keys at once.

Just wild guesses, really. That's why I turned to you guys, that I
figured would be more logical than me :-)

The battery is a definite possibility. The alarm is definitely more
than 5 years old, and although we haven't had a problem recently, the
power has flickered a lot this year.

Thanks, all,

Jason
