Guest Cate Posted June 20, 2020 Report Posted June 20, 2020 We have three fire alarms, one on each floor. One needed replacing so we got the Easichange for Ei166RC. The alarm works on test but it's not synced with the other two alarms. All three used to sync, how can we get them to all sound simultaneously when we is activated? Thanks Quote
