We have tested the alarms by pressing the test button and all interlinked alarms behaved as expected. As an extra level of testing we wafted some smouldering cardboard under them and they are not sounding an alarm, we have a Kitchen Heat Alarm fitted in the kitchen and that detected the smoke and heat source immediately.
It seems strange that 3 new Smoke Alarms are all faulty or are we doing something wrong, all have been installed as per instructions, have back up batteries installed . What have we done wrong , please help. I would feel a right idiot returning them to the supplier to find out I have done or not done something crucial.
Thanks in advance
