The Ei100MRF RadioLINK+Module is the next generation RF module designed to
fit in the Ei160e and Ei2110e series, Easi-fit mains powered Alarms. The Ei100MRF
RadioLINK+Module effectively replaces the Ei168RC RadioLINK Base.
The primary function of the Ei100MRF is to wirelessly interconnect all Ei Electronics
Alarms in a system by the means of an RF signal i.e. when one Alarm senses a fire
event, the Ei100MRF module attached to that Alarm will transmit an RF signal that
will activate the sounders in all other Alarms in the system.
The Ei100MRF module is plugged into the rear of the base of an Ei160e or Ei2110e
series Alarm. RF communication through this module eliminates the need to install
long interconnect wires between all the Alarms on different floors in different rooms.
The Ei100MRF is powered from the Alarm it is connected to.
The module also has “multiple repeater” transmission – this provides multiple signal
paths to create a robust RF ‘mesh’ system and also increase the RF range.
Introduction

N.B Disconnect Mains Before Alarm Head Removal
After disconnecting the mains power supply, it is now safe to remove the Alarm from
its base. Using a screwdriver, insert into the removal slot on the side of the Alarm.
Push the lower half of the Alarm away away from the screwdriver, in the direction
of the arrow on the cover (see Figure 1 below).
CAUTION: The existing hard-wired interconnection may need to be disconnected
at this point (refer to the Installation section in the Alarm instruction manual). If a
hard-wired connection and an RF connection exist between the SAME two Alarms,
a continuous Alarm loop signal may occur.

Installation and House Coding
Figure 1

Fitting the Ei100MRF Module
To fit the Ei100MRF Module, first hold the flexible antenna and guide it into its
designated hole in the rear of the unit until about 2/3 of its length is inserted (Fig.
2a). Then, hold the module housing (Fig. 2b) & plug it into the Alarm, being careful
to align the pins and keeping them perpendicular to the base as the module is
inserted (Fig. 2c). Ensure the module is fully home, by checking that it is flush with
the surrounding Alarm housing (Fig. 2d).

House Coding the Unit
Ensure that the Alarm is re-connected to the
base correctly by checking for the green LED
on the cover of the Alarm. Power supply to the
Ei100MRF will be confirmed by an initial flash
of the red, blue and green LED on the side of
the unit (see Fig 3).
Using a screwdriver, press and hold the House
Code button on the side of the unit until the
blue light illuminates (see Fig 4).
Immediately release the button, the Blue light
will flash rapidly and then stop.
The flashing will repeat every 5 seconds
thereafter. Repeat this procedure for all alarms
in the system and any RF accessories such as
the Ei450 Alarm Controller.
Check to ensure all RF devices have been successfully House Coded. This can
be done by counting the number of blue flashes on each RF Module. The number
of flashes should correspond to the number of RF devices in the system. (i.e. 4
flashes if there are 4 devices in the system).
N.B. We recommend, for ease of installation and RF communication, that up
to 12 RF devices can be installed in any one RF coded system. Please contact
us for further advise if additional RF devices are required.
You can exit this mode by pressing the House Code button on one of the RF Alarms.
Keep the button pressed until the blue light comes on solid and then release.

The Alarm will now send a signal to all the other RF devices in the system to exit
House Code. Alternatively, the RF Alarms will automatically exit the House Code
mode after 30 minutes. To check the system, press the test button on any Alarm.
After a few seconds all Alarms should now sound. All Alarms in the system should
be checked similarly. Caution: Do not House Code another group (e.g. adjacent
apartment) until the current House Code has been completed.
Factory Reset
Sometimes in order to resolve an RF communication issue it may be necessary
to reset (factory reset) and House Code the system again. To do so, press and
hold the House Code button until you see a flashing blue light on the Alarm cover
(approx. 7 seconds), release immediately. Repeat this procedure on all Alarms.
Removing the Ei100MRF Module
If it is necessary to remove or replace
an RF Module already fitted to an Alarm,
it can be taken out by firstly using your
index finger to lift it by 5 to 6mm to
release the connection pins (Fig. 5a),
repeat this process on the opposite end
to release the antenna (Fig. 5b), after
which the module can be fully removed
from the Alarm by lifting it away while
keeping the pins perpendicular to the
Alarm (Fig. 5c).
