The Ei105B is a Smoke Alarm that runs on a 9V battery (Supplied with the alarm)

Ei105B smoke alarms operate using the light scatter principle to detect smoke particles entering the optical chamber within the alarm.

The Ei105B is easily installed and comes supplied with all neccessary screw fixings.

The Ei105B is fitted with a warning flag that pops up when the bettery is removed. This prevents the cover from closing when there is no battery fitted to the unit. When the battery is being installed or changed, this flag must be held down while gently pushing the battery into the battery holder.

When the battery is first connected, the alaram may sound for 2-3 seconds - this is completely normal and means that the battery is connected correctly.
