Napco MA 2600

Hello,
My trusty alarm has been humming along without any issues.
I am now getting a system trouble notification and a "Call Service E1" message on my keypads.
I've looked for "E1" error codes in my ancient literature, but I'm not able to find what it means or how I can reset it.
As things stands I cannot arm the alarm.
Any pointers would be most appreciated.
As always, thanks for your help and advice..

All I see is that an E01 is a power failure.
Check the transformer for output. Check for the 16.5vAC to the panel.

Do other zones show as faulted when they are opened ?

I've checked the transformer(s) and power is getting to the panel.
Yes, other zones show as faulted when they are opened.

Thank you

-Not good news, actually. That's control panel program fault. Pretty much means that the content of the EEPROM is corrupted. The only real fix is clearing the program and reloading it.

Given that this hardware is circa 1989-1990 or thereabouts, it might be time to consider a hardware update. Your field wiring and contacts are probably fine, you need control, keypad(s) and possibly a zone expander, since this was a 16 zone system.

There's something else you might try. I'd suspect that you have never changed the small battery that's mounted under the small PC board on the face of the main board in the panel. It's somewhat hidden and somewhat of an arduous task to change it. I do believe I've seen some instructions on a website somewhere on the process of changing this battery. It's purpose is to maintain power for the memory when the system loses all power. I don't remember if the failure of this small battery is indicated by the E1 signal you are getting or not. But it wouldn't hurt to try and change it to see if it fixes the problem. DO NOT remove power from the panel while you are changing the small battery. If the small battery is completely dead, and you remove all power from the panel you will lose all of your programming.

I'm thinking that if the small battery is very weak and you lost power it may have corrupted the memory. After you change the small battery, clear the program and reprogram the system and you may be back in business.

Thanks.
Does anyone remember if this is a standard CR2032 battery.
At this point I have very little to lose.

I know it's one of the standard large button batteries, but exactly which, I can't recall.
