Product Description  
Operation  
The Ei141 is an Ionisation Smoke Alarm that runs on  
230V AC mains power, and has a 9V alkaline battery  
back up in the event of mains failure. The 9V battery will  
last for up to 4 years in standby mode, and capable of  
powering the smoke detector for up to 2 years in the  
event of mains failure.  
The green indicator will illuminate to show mains  
power is present  
The red indicator will flash rapidly to show an alarm  
condition for the smoke detector  
The “Test/Hush” button will either silence false  
alarms or perform a unit self test  
The Ei141 is supplied with the Easi-Fit base that allows  
very quick and simple installation of the smoke alarm,  
combined with simple detector head removal and  
replacement. The Easi-Fit base automatically connects  
both mains power and battery as the detector head  
slides on to the Easi-Fit base.  
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  
The Ei141 has other advanced features such as the  
ability to interconnect up to twelve alarms to allow all  
alarms to sound if just one of the interconnected alarms  
should be triggered.  
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 Ei141 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 smoke detector will emit a beep every 40  
seconds to indicate that the battery back up is  
depleted and needs recharging
