Product Description  
Operation  
The Ei3105RF is an Optical Smoke Alarm that runs on  
9V alkaline battery and is part of the Radio Frequency  
range of smoke alarms. The RF signal will wirelessly  
interconnect the Ei3105RF to other RadioLINK products  
The red indicator will flash every 40 seconds to show that  
the detector has performed an automatic self test  
In normal standby mode the amber indicator will light to  
indicate transmission of an RF signal  
The Ei3105RF uses advanced radio transceiver  
technology with unique software coding to transmit and  
receive the radio signals. The transmissions are  
frequency modulated (FM) and use Manchester coding  
to ensure robust signal integrity and avoid signal noise  
interference  
In code mode, the amber indicator will flash to indicate the  
number of other RF alarms that have been “learned” in the  
system  
The red indicator will flash rapidly to show an alarm  
condition for the smoke detector  
The Ei3105RF has other advanced features such as high  
performance optical chambers fitted with integral insect  
screens to reduce the chances of false alarms, as well  
as the ability to wireless interconnect up to twelve alarms  
to allow all alarms to sound if just one of the  
The “Test/Hush” button will either silence false alarms or  
perform a unit self test  
In “Hush” mode the alarm enters a ten minute period of  
reduced sensitivity and the red light flashes every 10  
seconds and then resets  
interconnected alarms should be triggered.  
The Ei3105RF has built in circuitry to aid suppression of  
voltage transients and RF interference to further reduce  
the chances of false alarms under such conditions  
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 smoke detector will emit a beep and the red light  
flashes every 40 seconds to indicate that the battery is  
depleted and needs to be changed
