Product Description

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 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

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
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

Operation

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

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 “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

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

Installation & Placement

Place the alarm on the ceiling/wall and mark the screw holes. Drill with a
suitable drill bit, insert the screw plugs and screw the alarm into position.
Simply connect the battery on the alarm and slide into position on the
mounting plate.

The RF alarms should be house coded to prevent possible interference from
neighbouring installations – see instructions for more details.

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

House Code Procedure

1. Connect the battery

2. Press the house code switch
until the amber light turns on
and then release

3. Similarly, place other alarms
into house code mode

4. Check that the number of
amber flashes (on each
alarm) corresponds to the
number of alarms in your
system

5. Remove all alarms from
house code

6. Button test each alarm to
check your system
