The Smoke/Heat Alarm is mounted on the EI 128R and when a fire is de-

tected the relay contacts change over. The electrically isolated contacts

can be used for signalling, turning on lights etc.

WARNING: This pattress must only be used with one of the above smoke

alarms as per these instructions - otherwise the unit will not comply with

the mandatory safety regulations.

With the yellow slide switch “on” (as supplied) the relay changes over

when the fire is detected and only resets when the smoke/heat alarm re-

sets. With the slide switch “off” the relay changes over for 2 to 12 seconds

when fire is detected and then resets – this is useful with warden call pan-

els. If momentary operation is required, push the slide switch gently and

carefully with a screwdriver to turn it off.

WARNING: Mains powered Smoke/Heat Alarms should be installed by a

qualified electrician in accordance with the Building Regulations for Elec-

trical Installations published by the Institution of Electrical Engineers

(UK). Failure to install the unit correctly may expose the user to shock or

fire hazards.

Warning: First disconnect the mains from the circuit to be used.

1.Chose a mounting position following the siting instructions in the

Smoke/Heat Alarm leaflet. Where the incoming wiring is on the surface of

the ceiling, the appropriately sized ducting/conduit must be chosen to

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

lected knockout, making sure that there is no gap when mated with

ducting / conduit. There are three knockouts – two on the sidewall and

one on the rear.

2.Screw the pattress EI 128R to the ceiling after first removing the re-

quired knockout and bringing the house wires through it (see figure 1). If

the central knockout is being used, seal around the wires with silicone or

similar to prevent air draughts affecting the smoke entering the alarm.

3.Connect the house wires (L - Live, N - Neutral and IC - Interconnect, if it

is being used) to the terminal block on the pattress. If an EI 161R or EI

166R (with remote TEST/HUSH) is being installed, attach the “R” wire

from the EI 152 (see the EI 152 instruction) to the terminal marked “R” in

the pattress (see figure 1). If the EI 161R or EI 166R is being used with a

manual call point MCP400 or MCP400A then connect the R terminal to

the call point (see figure 2). Otherwise do not connect anything to the ”R”

terminal.

4.Connect the three wires (“L”, “N” and “IC”) from the pattress to the con-

nectors on the Smoke/Heat Alarms mounting plate. This “IC” wire must

be connected even if it is a single alarm installation. Connect the earth

wire (if present) from the house wiring directly to the terminal on the

mounting plate. Replace the cover over the terminal wires.

Connect the wires to the required relay contacts for controlling the auxil-

iary device (the contacts are isolated and are rated at 250VAC, 5 amps re-

sistive). If momentary relay operation is required, carefully and gently

slide the yellow switch to the off position with a small screwdriver (see fig-

ure 1).

5.Screw the mounting plate to the pattress pillars using the two screws

supplied.

6.Slide the alarm on to the mounting plate.

7.Connect the mains power – the green LED light on the alarm should be

on. When the test button is pressed the horn should sound and the relay

will switch within 10 seconds. (Note - with ionisation alarms the relay nor-

mally switches 4 seconds after the horn sounds. With optical alarms the

relay normally switches within 2 seconds of the horn sounding).

Note 1: A maximum of 12 Smoke/Heat Alarm of the types specified may

be interconnected to one EI 128R unit. When one alarm senses fire all in-

terconnected units will alarm and the relay will switch.

Note 2: An alarm with battery back-up will continue to operate during a

mains failure but will not be able to switch the relay. (The relay requires

the 230 VAC to operate).

Note 3: Devices connected to the relay contacts must not give a fire warn-

ing until the contacts have switched for at least 200mSec. (The contacts

may switch momentarily when subjected to electromagnetic interfer-

ence).
