How can I fix my Scantronic 500r alarm?

Hi Bob,

Just to say...I'm in the same boat as you :-(

Inherited the alarm system (500r)

I've got the user code but the engineer code has been changed from the default so can't disarm to replace detector batteries.

Let me know if you find a solution and I'll do the same.

Kind regards,
John
