RADIOLINK RELAY

FOR USE WITH EI168, 405, 405TY & 3105RF

Instruction Manual

MODEL Ei428

Contains vital information on the products 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

smoke/heat 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

RadioLINK products (Ei168, 405, 405TY, 407, 410, 411 &

3105RF).

The Ei428 RadioLINK Relay Module is powered by the

230VAC mains and has rechargeable back-up cells. As sup-

plied the relay operates continuously (i.e. it switches when

one of the smoke / heat alarms detects fire and switches back

when the smoke clears). When the slide switch is moved to

the pulse ‘P’ position (see figure 1b) the relay will switch when

fire is detected but will automatically switch back after 5 sec-

onds. This is commonly used with warden call systems where

only momentary short circuit signalling is required.

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.

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 cylin-

der, 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 ceiling,

the appropriately sized trunking / conduit must be chosen to

mate with the unit. Use a sharp knife to remove the material
