Guest Mark Posted March 22, 2017 Report Share Posted March 22, 2017 Hi, my EI smoke alarm is sounding three short beeps. I have changed the battery, hoovered out and wiped down the unit and checked the best before date (2021). The unit is not even a year old but it is sounding 3 beeps roughly every minute still. How do I solve this without resorting to using a hammer. Thanks, Mark Quote Link to comment Share on other sites More sharing options...
Safelincs Posted March 23, 2017 Report Share Posted March 23, 2017 Hi Mark EI alarms do not give three beeps. I suspect you might have a CO alarm nearby with low battery. To double check, take your alarm of the ceiling, press the test button to drain any charge still left. I assume you will still hear three beeps.
