The 9V battery will last for up to 4 years in standby mode, and capable of powering the heat detector for up to 2 years in the event of mains failure. The Ei144 is supplied with the Easi-Fit base that allows very quick and simple installation of the heat alarm. The Easi-Fit base automatically connects both mains power and battery as the detector head slides on to the Easi-Fit base. The Ei144 has the ability to interconnect up to twelve alarms to allow all alarms to sound if just one of the interconnected alarms should be triggered. The Ei144 has built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions. The Ei144 heat alarm gives a fire warning when the 0 temperature at the unit reaches 58C. Heat alarms are ideal for use in kitchens and garages, where the use of optical or ionisation alarms would lead to unwanted nuisance alarms. On escape routes this alarm must be interconnected with smoke alarms. Operation The green indicator will illuminate to show mains power is present The red indicator will flash every 40 seconds to show that the detector has performed an automatic self test The red indicator will flash rapidly to show an alarm condition for the heat detector The “Test/Hush” button will either silence false alarms or perform a unit self test In “Test” mode the alarm will perform a self test and sound the horn In “Hush” mode the alarm enters a ten minute period of reduced sensitivity to overcome false alarm conditions, and will then automatically reset itself When interconnected to other Ei mains powered alarms, an alarm on one detector will trigger all other interconnected alarms within one second (only the triggered alarm will flash a red indicator) The heat detector will emit a beep every 40 seconds to indicate that the battery back up is depleted and needs replacing Shannon Free Zone, Shannon, Co.

Wiring for Interconnected Alarms The wiring can be installed when appropriate. (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.. Connect wires to the unit as in wiring diagram. All wiring must Be very careful about correctly wiring the alarms as mixing Live and Neutral comply with local codes. will blow/damage interconnected alarms. Locate heat alarms in rooms adjoining or on escape routes – kitchens, garages, boiler houses etc. where smoke alarms are unsuitable. Install within 5.3m of potential sources of fire.
