I have two mains wired smoke alarms (they also have PP3 batteries fitted). One is at the bottom of the stairs and one is at the top. Both of the alarms look absolutely identical but, one of them is an Optical Smoke Alarm and the other is an Ionisation Smoke Alarm. This doesn't mean anything to me I'm afraid. However, I would be most appreciative if someone could explain the difference please.
A week ago both of these alarms went off at the same time, 3.45am (middle of the bloomin night!) and I could not find a cause. They both went off again today but this time we were up and about at 6.45am. Once again there is no obvious cause. Almost a full week has passed by without a further incident.
I know that if the batteries are going then they tend to beep about once a minute but, both of these occasions it was a full blown alarm.
Just wondering if anyone on here has any inkling as to what might be causing them to go off without any obvious cause.
Many thanks for reading
