The alarm has eased to operate on the front door (set to zone 1). It no longer "chimes" when opened and doesn't cause the alarm to go off if opened when the alarm is set.
The back door (set to zone 2) continues to work with "chimes" and activates the alarm. I have tested the five movement sensors and they all activate the alarm.
Why would the alarm on the front door suddenly stop working? There has been no work or DIY done anywhere near the door or the alarm system.
Appreciate someone's help.
Thank you
