Have replaced old battery and control panel today but with another A1 Omnicron 7000 panel which i had as spare having plundered the bell box and pirs from the box over the years.

Everything appears to be working with the exception of Night time security and zone omit. If i omit zone 4 upstairs for the night i require zone 3 as a walkthrough to get to the alarm to disarm, however the instruction book states that the entry/exit zone1 has to be activated first otherwise an instant alarm will result. I have set zone 3 as a walk through however as stated when i come down the stairs the zone 3 pir activates the alarm immediately.

It used to work ok with the old control panel but i can

Many thanks to Mark at your suggestion i set zone 3 as an Entry/Exit zone as this has resolved the issue
