Hi there
I have the following alarms that I purchased from Safelincs 5 months ago.
The alarm models are:
1. Carbon Monoxide Firex 4985
2. Firex Ioisation 4881
3. Firex Ionisation 4870
4. Firex Optical 4985
All has been ok but suddenly the alarm beeps once every 10 minutes.
I have cleaned all the alarms and changed the backup battery on one of them that allows you to replace the battery. All alarms are wired into the electrical circuit.
Does anyone have any advice as to why this is happening and what I can do to stop it.
Thanks in advance.
Dan
