Product Description
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.
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)
Green power on LED
–flashes every 40 seconds
Circular Easi-Fit mounting base for quick installation
Relay operates in continuous or pulse mode
