DSC 1500 - Power Outage issue

I have a DSC 1500 model and have id'd my "programmers code" as 1500. I recently lost power for an hour and beleive my b/u batter to be dead. When power was restored my alarm sounded off in 3 short bursts in a continuous loop. To stop the sound, i just need to push any of the buttons on my keypad. All 6 zones show a red light...none of the other lights are on. The alarm loop begins again in approximately 1-3 minutes after a button has been pushed.

I've since unplugged the alarm while i try to figure out a solution. I'll be purchasing a new battery today but am stuck after that.

I've downloaded the programmers manual and have the worksheet though I'm still not able to figure this out. Any insight would be greatly appreciated. All I want to do is be able to arm my alarm again.

A quirk of the old PC1500 panels is that if they are allowed to run on a failing battery, the program can become corrupted. What you will have to do is follow the instructions for the hardware default that are in the installer manual, then reprogram all of your zone settings.

You will need to temporarily disconnect whatever's on zone 6, because when this corruption happens, that zone reverts back to the factory default setting of being a fire zone, which is why your siren is doing the 3 burst audibles.

So I followed the manual for code 11 (zone definitions) and finally got rid of the "fire alarm" but am now stuck with an alarm that won't arm. The Trouble light is green and all zones (1-6) are red.

My apologies if I seem slow on this. Any additional toughts?

BTW - this is crazy...I pour through financial instrument docs everyday and this much more difficult to understand!

Turn OFF option 5 in programming location 12. For various reasons, nearly all DSC residential installers disable the EOL resistors but the feature turns back on when the system defaults.

Alarm systems are not intuitive, somewhat by design...

If you had an audible exit delay, before, then you must have had one of the later models. In that case you turn ON option 1 in programming location 34.
