Introduction
Congratulations on purchasing an Ei600 Series RF RadioLINK module. These RF
modules can be easily installed in the Ei600 Series Alarm to provide you with an RF
interconnected fire warning system – when one Alarm senses fire and sounds a
warning, all the other Alarms will also sound a warning. This helps to ensure the
alarm sound will be heard throughout the property.
Installation
1. The Ei600 Series Alarm must be installed as per the guidance in the instruction
booklet ‘Battery Powered Smoke & Heat Alarms’.
2. Remove the RF module from the packaging and using the pull tag, carefully
insert into the back of the Alarm (see figure 1) - (some Alarm models may have the
RF Module already fitted).
3. Ensure that the battery is connected in the 9V Replaceable Battery Models.
House code the Alarms as follows:
4. Before fitting the Alarm to the mounting plate, press and hold the ‘House Code’
switch on the rear of the RadioLINK module until the red light comes on (see
Figures 2a) and then release.
5. Twist the Alarm onto its mounting plate.
6. Similarly press and hold the House Code switch on the second Alarm until its red
light comes on and then release. Twist the Alarm onto its mounting plate. Put all the
remaining alarms into House Code mode similarly and attach to the mounting plate
in the same manner in less than 15 minutes. (They automatically exit house code
mode after 30 minutes).

7. When in the House Code mode, the blue light (on the front of the Alarm - see
figure 2b) will flash a number of times every 5 seconds to indicate:
(a) that the Alarm is in House Code mode,
and
(b) the number of Alarms that have been identified and added to your system.
For example with 3 Alarms in your system, you should see 3 blue light flashes every
5 seconds, with 4 Alarms in your system you should see 4 blue light flashes and so
on, (with the 10th unit, the blue flash is longer, to help with the counting).
Check that the number of blue light flashes corresponds to the number of Alarms in
the system. If not see the “RadioLINK Troubleshooting” section below.

8. The Alarms will stay in House Code mode for 30 minutes and then reset
automatically. Alternatively they can be taken out of House Code mode by removing
one Alarm from its mounting plate and quickly pressing and holding the House
Code switch until the red light comes on solidly again. Release the switch and the
red light will go out immediately, indicating that the Alarm is no longer in House
Code mode. Replace the Alarm on the mounting plate. The blue light will no longer
be flashing.
Note: As this Alarm exits house code mode it sends a radio message to all the
other Alarms to exit the house code mode. Check that all the blue lights on the rest
of the Alarms have ceased flashing. (Accessories must be taken out of house code
manually - see their instructions).
9. Button test all Alarms in turn and check all the other Alarms are sounding at the
same time. If they are not all communicating see section below “RadioLINK
Troubleshooting”.
