Aico Battery Optical Alarm

The Ei650 Battery Optical Alarm operates on the light scatter principle todetect smoke particles entering the optical chamber. This optical alarm is sensitive to all domestic fire types but is especially sensitive to visible smouldering fires. The Ei650 Battery Optical Alarm is supplied with screw fixings with simple to install twist on base. The twist on action activates an internal switch and powers on the Alarm.

The Ei650 is fitted with a large easy to use Test/ Hush button to facilitate frequent testing of the alarm. The Test button can also be used to silence nuisance alarms, e.g. cooking fumes, for a 10 minute period. The sounder will automatically stop sounding when smoke particles are no longer present in the chamber. The Ei650 Battery Optical Alarm performs a self check it’s chamber sensor, battery voltage and internal circuitry every 40 seconds. Any fault condition found will be indicated by a combination of red LED flashes and/or audible beeps.
