RadioLINK
RELAY BASE
Instruction Manual
Contains vital information on the product’s operation and
installation. Read and retain carefully. If you are just installing
this product the manual MUST be given to the householder.
1. Introduction
The Ei428 RadioLINK Relay Module is a device that switches
a relay upon receipt of an alarm signal from a suitable Ei
Alarm. The electrically isolated contacts can be used for many
applications such as signalling, turning on lights, etc. The
Ei428 is designed to operate with Ei RF devices.
The Ei428 RadioLINK Relay Module is powered by the
230VAC mains and has rechargeable back-up cells. As
supplied the relay operates continuously (i.e. it switches when
one of the Alarms detects fire and switches back when the
alarm condition is finished).
2. Installation
WARNING: Mains powered Ei428 RadioLINK Relay modules
should be installed by a qualified electrician in accordance
with the Regulations for Electrical Installations published
by the Institution of Electrical Engineers (UK) (i.e. BS7671)
Failure to install the unit correctly may expose the user
to shock or fire hazards. This unit is not waterproof and
must not be exposed to dripping or splashing. The Ei428
must only be installed in a building installation where
an appropriate disconnect device has been fitted (i.e.
all-pole mains switch).
1. Choose a suitable mounting position near the mains supply
and the device to be connected to the relay. Keep it away
from metal surfaces or large metal objects (e.g. water
cylinder, fuse boards) which can reduce the RF signal range.
2. Disconnect the AC mains supply from the circuit that is
going to be used.
3. Where the incoming wiring is on the surface of the wall/
ceiling, the appropriately sized trunking / conduit must be
chosen to mate with the unit. Use a sharp knife to remove
the material from the knockout, making sure that there is no
gap when mated with trunking/conduit. There is one suitable
surface cabling knockout (the other two surface entries are
not recommended as the wiring will reduce the antenna
signal). There is one rear entry knockout. See figure 1b.
4. Screw the Ei428 module to the wall after first removing the
required knockout and bringing the house wires through it
(see figure 1b).

Model: Ei428

5. Connect the house wires (L-Live to wires coloured brown,
red or marked L, N-Neutral to wires coloured blue, black or
marked N) to the terminal block as shown in figure 1b.
NB: The unit must not be earthed so do not connect a green
/ yellow or copper earth wire to any terminal.
6. Connect the wires to the required relay contacts for controlling
the auxiliary device. (The contacts are isolated and are rated
at 250VAC, 5 amps resistive).
If momentary relay operation is required, carefully and
gently slide the yellow switch to the “P” position with a small
screwdriver (see figure 1b). This is commonly used with
warden call systems where only momentary short circuit
signalling is required. This must be done before the mains
power is connected or the rechargeable cells are activated.
With the switch in the “C” position, the alarm signal will
switch the latching relay until it receives a cancel signal.
7. Connect the rechargeable cells by carefully and gently sliding
the switch to the “ON” position (see figure 1b). This switch
must be in the ‘on’ position to ensure correct operation.

8. Fit and screw the cover to the module pillars using the two
screws supplied.
9. Connect the mains power to the Ei428 module. Check the
green light is on. If the green light changes to red every
10 seconds then switch off the mains power, remove the
cover and check that the battery slide switch is in the
“ON” position (see figure 1b). Replace the cover and turn
the mains power back on. If there is still a problem the
rechargeable cells may be depleted, leave the unit on
mains power for 2 hours to charge and test again.
10. Press and hold the House Code switch through the hole
in the cover using a small screwdriver, see figure 1a, until
the green light changes to red. Release the switch and the
light will flash red quickly, a few times. The red light will
then flash every 5 seconds.
11. House code all other RF Alarms and devices in the
system. Consult the instruction manuals on how to house
code the Alarms and devices. It is essential that each
individual Alarm/device is put into House Code mode in
its final location.
12. Check the number of flashes on the Ei428 and on every
other device. They should correspond to the total number
of devices in your system. A system with 3 Alarms and 1
Ei428 will result in 4 flashes. It may take up to 10 minutes
before all 4 flashes are seen.
The flash pattern will repeat every 5 to 10 seconds
while the Ei428 remains in house code mode. If it fails
to flash the correct number of times, then consult the
“Troubleshooting” section of this instruction manual. To
complete the commissioning, the RF system must exit
House Code mode.
13. The Ei428 will automatically exit House code mode after
30 minutes. Other devices may exit after only 15 minutes.
Once coded, the system will not communicate with any
other RF Alarms and devices outside of the house coded
group.
To manually exit House Code mode, press the House
Code button again on the Ei428 until the RF indicator
lights up red, then release. This will send a signal to all the
other RF Alarms and devices to exit House Code mode.
After a short period, the red light will turn off and the
system will return to standby mode. Depending on the
number of RF Alarms and devices in the system this
period could vary from 5 to 20 seconds.
Note: Not all devices are able to receive the Exit House
Code mode signal from another device. If some devices
continue to flash amber / red, please consult their
instruction manual to manually exit house code mode.
Check that the RF indicators have stopped flashing on
all devices.
14. To check the system, press the Test button for up to 60
seconds on any house coded Alarm. After a few seconds
3

all Alarms should sound. Ensure that the device connected
to the relay contacts operates. After 60 seconds release
the test button – check the device switches off. (If the
continuous/pulse slide switch is in the pulse position,
check the relay just switches on for 5 seconds and then
switches off). All RF devices in the house code system
should be checked similarly.
3. Troubleshooting RadioLINK
If, when checking the radio link interconnection, some of the
Ei428 RadioLINK Relays do not respond to the button test, then:
(i) Ensure you have held the smoke/heat alarm test button down
until the RF light comes on (this could take up to 40 seconds).
(ii) Re-locate/rotate the units. There are a number of reasons
why the radio link signals may not reach all the RadioLink
Relays in your system (see section on “Limitations of Radio
Frequency Signals”). Try rotating the unit or re-locating the
units (e.g. move them away from metal surfaces or wiring)
as this can significantly improve signal reception.
Rotating and/or relocating the units may move them out of the
range of existing units even though they may have already
been house coded correctly in the system. It is important
therefore to check that all detectors/relays are communicating
in their final installed positions. If units are rotated and/
or resited, we recommend that all units are returned to the
factory settings (press and hold the house code switch on for
about 6 seconds until the relevant light comes on and then
flashes slowly). Then house code all units again in their final
positions as indicated above. The RadioLink interconnection
should then be re-checked again.
4. Checking & Maintaining Your Smoke Alarm
System
We recommend a weekly check is made of your alarm system.
When checking the system also check the Ei428 as follows:
(i) After 10 years (see date on the side of the RadioLink
Relay Base) the Ei428 Relay module must be replaced.
(ii) Check that the green mains power indicator is on (if this
is off, check circuit breaker fuse, wiring etc.). When the
mains is restored the green light will come on solid.
(iii) The light flashing red every 10 seconds indicates a battery
problem. Check that the slide switch is in the “ON” position
(See fig 1b) and leave the battery to recharge for 2 hours
before checking again. If the unit continues to flash red
every 10 seconds then the unit is defective and must be
replaced, see “Getting your Relay Base Serviced” section.
(iv) Check the relay switches and that the associated device
operates when the system is in alarm (e.g. due to a smoke
alarm test button being pressed).

8. Limitations of Radio Communications
Ei Electronics radio communication systems are very reliable
and are tested to high standards. However, due to their low
transmitting power and limited range (required by regulatory
bodies) there are some limitations to be considered.
(i) Radio equipment, such as the Ei428 RadioLink Relay,
should be tested regularly at least weekly. This is to
determine whether there are sources of interference
preventing communication. The radio paths may be
disrupted by moving furniture or renovations, and so
regular testing protects against these and other faults.
(ii) Receivers may be blocked by radio signals occurring on
or near their operating frequencies, regardless of the house
coding.
This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
and television reception.
However, there is no guarantee that interference will not occur
in a particular installation. If this device does cause such
interference, which can be verified by turning the device on
and off (remove the mains supply and turn off back up power
supply), the user is encouraged to eliminate the interference
by one or more of the following measures:
(i) Re-orientate or re-locate the unit.
(ii) Increase the distance between the Ei428 and the device
being affected.
(iii) Connect the device being affected to a mains outlet on a
circuit different from the one that supplies the Ei428.
(iv) Consult the supplier or an experienced radio/television
technician.
