The Ei100B ionisation smoke detector will activate the built in sounder upon sensing smoke particles. The Ei100B ionisation smoke detector will automatically reset itself and silence the sounder when smoke particles are no longer present in the sensing chamber.The built in sounder will provide a minimum sound output of 85dB at 3m 

The Ei100B ionisation smoke detector has a built in warning flag to prevent installation of the detector without a battery fitted 

The “Test” button will perform a self test and sound the horn (it may take up to 10 seconds) 

The Ei100B ionisation smoke detector will emit a beep every 40 seconds to indicate that the battery back up is depleted and needs replacing
