Model Ei 181 Ionisation High sensitivity – responds to all standard fires Dual Ionization chamber - quick response fast flaming fires Supply voltage 10.5 to 30 volts Interconnect up to 12 alarms Relay contacts Built in sounder Test button Kitemarked to BS EN 14604:2005 5 year guarantee 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. 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 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. Shannon Free Zone, Shannon, Co. Clare, Ireland. Ph.+353 61 471277 Fx.+353 61 471053 Email.

Ei181 DataSht RevB Model Ei181 Ionisation Technical Specification Alarm: Piezoelectric-horn in unit Sensor Ionisation, uses electrically charged ions that will react to smoke particles Sensitivity: Complies with BS 5446 Part 1: 2000 Temperature Range: 0 to 40°C Source: Americium 241 Humidity Range: 0% to 90% Relative Humidity Airspeed: Essentially immune to the effect of airspeed. Fixing: Screw fixings supplied Plastic material: UL94HB flame retardant Button Test: Simulates the effect of smoke and checks chamber, electronics and horn. Dimensions: 145 diameter 65 mm height Weight: 334 gram Warranty: 5 year (limited) warranty Approvals: Kitemarked to BS EN 14604:2005, CE Approved Alarm Sound Output: 85dB (minimum) at 3m Supply Voltage: 10.5 to 30 volts Specifications are subject to change Installation & Placement Important Precaution: Do not install the actual smoke/heat alarm itself in new or renovated buildings until all work is completed (including floor coverings) and the building has been fully cleaned. (Excessive dust and debris from building work can contaminate the smoke chamber and cause problems, and it will also invalidate the guarantee). If it must be installed, cover it completely, particularly around the edges, with a dust cover (eg. a plastic bag), until all cleaning is finished.. Alarms should be placed in accordance with the general guidelines shown in the diagram above. These recommendations are based on the problem of areas of “dead air” close to corners of rooms and apexes of ceilings, which could result in the prevention of smoke reaching the smoke detector Please consult the Instruction Leaflet supplied with the Ei181 for detailed instructions as to how to correctly install and position the smoke detector Shannon Free Zone, Shannon, Co.
