Smoke Alarm Mode Ei 100R Ionisation High sensitivity - responds to all standard fires Dual Ionization chamber - quick response fast flaming fires Supply voltage 10.2 to 14 volts Interconnect up to 12 alarms Relay contacts Built in sounder Test button Kitemarked to BS5446-1:2000 5 year guarantee Product Description The Ei100R is an Ionisation Smoke Alarm that is designed to operate with suitable 12 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. Operation The smoke detector will activate the built in sounder upon sensing smoke particles The 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 “Test” button will perform a self test and sound the horn (it may take up to 10 seconds) Red LED -flashes every 40 seconds to indicate unit checks Interconnect up to 12 other alarms (9V ionisation, optical or heat) when one senses smoke, all a...
