I'm constantly get call outs from where I work, for false activation of domestic alarms. Think its down to the cheapo alarms and thunder flies. Although once, when I was inspecting the head, an ordinary fly fell out of it.02.00 this morning and I woke half way through the bedroom door to the sound of smoke alarms all sounding. 2nd time it has happened with the Firex units fitted in this house (middle of the night both times) and on different heads each time. No idea of the cause - obviously no smoke or heat and I can't see it being dust as they get lightly vacuumed each month in a fairly recently built house.
Disconnecting the head and removing the back up alkaline battery for a few minutes clears the issue and shows a green light, but I'm not sure they'll be here long enough for a 3rd false alarm...
