Repeater and CO Alarm Interface
FOR USE WITH Ei261ENRC, 151TL, 154TL AND 156TLH
COMMUNICATES WITH ALL OTHER RADIOLINK DEVICES
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 Ei420 can be used for two purposes:
(1) It connects the Ei260ENRC Series Carbon Monoxide Alarms
with RadioLINK Smoke Alarms and accessories. When the CO
Alarm detects CO it will trigger all the other RadioLINK units
and vice versa. It can also be used to connect Ei151TL, 154TL
and 156TLH smoke/heat alarms to other RadioLINK units.
Note: anytime the CO alarm is mentioned in these instructions
it can also be applied to the Ei150 series of smoke/heat alarms.
(2) It can be used as a stand-alone RadioLINK Repeater unit
in installations that require additional signal coverage but where
the installation of an additional alarm may not be suitable.
Installing an Ei420 in an intermediate position will shorten
and/or provide multiple RF signal paths.
It is powered by 230V AC mains power and has built in
rechargeable Lithium cells. It is a stand alone model with its
own cover plate.
The Ei420 uses advanced transceiver and signal coding
technology to ensure robust and reliable RF signalling.
2. Installation
2.1 RadioLINK Interface to an Ei260ENRC Series CO Alarm
If purchasing the Ei420 as a RadioLINK interface with a CO
alarm then it should be mounted close to the alarm. It can be
mounted a short distance away as shown in Figure 2 or it can
be mounted directly above the alarm as shown in Figure 3.
Choose a suitable mounting position near the mains supply
but keep the Ei420 away from metal surfaces or large metal
objects (e.g. water cylinder, fuse boards) which can reduce
the RF signal range.
2.2 As a Repeater
The function of a Repeater is to receive and then re-transmit
the RF signals. This shortens signal paths throughout the
installation to give improved RF signal reliability. If purchasing
the Ei420 for use as a Repeater it should be mounted in an
intermediate position where the RadioLINK signal needs to be
strengthened (for example see figures 1(a) and 1(b)). The
Repeater function is not operational until all units have been
House Coded (see individual instruction lealets). The operation
of the Repeater can be observed as the Ei420 turns on its red
light as a RadioLINK message is being repeated. A maximum
of 10 RadioLINK units (e.g. Ei168RC and Ei420 units) can be
set as Repeaters in any one system. If using more than 10
units within a system see Section 8 (Technical Specification).
2.3 Mounting and Wiring
WARNING: Mains powered modules should be installed by a
qualified electrician in accordance with the Requirements for
Electrical Installations, 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.
1. Disconnect the AC mains supply from the circuit that is
going to be used.
2. 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. There is one suitable surface
cabling knockout as shown in Figure 3 (the other two surface
entries are not recommended as the wiring may effect the
antenna signal). There is one rear entry knockout (see Figure
3.) Unscrew the cover attachment (see Figure 3). Use a sharp
knife to remove the material from the knockout, making sure
that there is no gap when mated with trunking/conduit.
3. Screw the Ei420 to the wall or ceiling after first removing the
required knockout and bringing the house wires through it
(see Figure 3).
4. Connect the house wires to the terminal block as follows:
L-Live to wires coloured brown or marked L,
N-Neutral to wires coloured blue or marked N
IC- Hardwire Interconnect to an Ei Electronics mains powered
alarm as shown in Figure 4(a) and Figure 4(b). Note: when the
Ei420 is being used as a stand alone repeater, do not connect
anything to the Interconnect terminal (see Figure 5.)
NB: The unit must not be earthed so do not connect a green /
yellow or copper earth wire to any terminal.
5. Activate the rechargeable cells by carefully and gently
sliding the switch to the “on” position (see Figure 3). This
switch must be in the ‘on’ position to ensure correct operation.
6. Fit and screw the cover to the Ei420 using the two screws
supplied.
7. Connect the mains power to the Ei420 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 3). 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 check that the green light is now on continuously.
8. Press and hold the House Code switch through the hole in
the cover using a small screwdriver, (see Figure 3) until the
green light changes to red. Immediately release the switch
and the light will flash red quickly. The green light will then
flash red every 5 seconds (this is a dual colour light so the
green light remains on when the red light is off and vice
versa). Similarly, put all the other RadioLINK units in the
property into House Code Mode (see relevant user
instructions) within 15 minutes (before the House Code
timeout period expires).
9. Check that all the RadioLINK units communicate with each
other by counting the number of times the light flashes on each
unit in turn. The light will flash red on the Ei420. For example,
3 units in the system should result in 3 flashes every 5
seconds, 4 units should result in 4 flashes and so on (if there
is a problem see Section 4 on Troubleshooting RF Link).
10. All the units will automatically exit the House Code Mode
after 30 minutes. However, we recommend that you manually
exit the House Code Mode by pressing and holding the House
Code switch on the Ei420 or on an Ei168RC until the House
Code light turns on solidly. Immediately release the House
Code switch. The light should stop flashing and an “Exit House
Code” signal will be sent to all other Ei168RC and Ei420 units
in the system. (With other RadioLINK units such as the Ei405,
Ei407, Ei411 etc., the units can be taken out of House Code
Mode by pressing their House Code switch - see their
instructions for details). This reduces the risk of accidentally
House Coding your alarms with other RadioLINK systems.
(Note: To clear House Codes see Section 8 - Technical
Specification).
