Hi, only when I added my Envisalink 3 to my HA at the cottage did I noticed the same behavior on my Envisalink 4 in my home HA. The Fire icon is checked when there is no fire. Is that normal? Both fire detectors are of 2 wires type, not the 4 wires one if it matters. Scared me when I noticed it because I was configuring the cottage Envisalink/DSC integration from home and saw the Fire zone checked
