I’ve got issues with my alarm expanders. I have 1 wired 8xp exp on 1 and a 32xp-w on 2 which should show that it uses 2,3,4,5 and a 2nd 32xp-w on 6,7,8. This was the case and it worked for 5 years perfectly. We had a power cut which has happened before but this time the alarm lost 3,4,5,7,8 and what ever I do nothing returns. Have new wireless expanders & still expanders do no show the lost one?
