Ei Electronics RadioLINK Ei428 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.
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).
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).
