SMOKE DETECTOR EI181

The Ei181 is an Ionisation Smoke Alarm that is designed to operate with suitable 8-30 volt control panels and to provide a loud local alarm. Ionisation smoke alarms operate on the principle that electrical current flowing between electrodes in an ionization chamber is reduced when smoke particles enter. Ionisation technology gives a rapid response to fast flaming fires Relay contacts (normally open and closed supplied) are available for triggering the panel itself and its associated ancillary products, such as extra loud sirens, magnetic door holders, etc. The alarms can be interconnected so that when one alarm senses fire, all the units located throughout the premises sound. Battery back-up insures the units are always powered, even during a power failure. The Ei181 is easily installed and comes supplied with all necessary screw fixings.
