1.Chose amounting position following the siting instructions in the

Smoke/Heat Alarmleaflet.Where the incomingwiring is on the surface of

the ceiling,the appropriatelysized ducting/conduitmustbechosen to

mate with theunit.Use a sharp knifeto remove to materialfrom the se-

ducting /conduit.There are three knockouts– twoon thesidewall and

one on the rear.

2.Screw thepattress EI 128R to theceiling after first removing there-

quired knockoutand bringingthe housewires throughit (seefigure 1).If

thecentral knockoutisbeing used,sealaroundthe wireswithsilicone or

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

3.Connect thehouse wires (L - Live,N - Neutral andIC - Interconnect,if it

is being used) tothe terminal block on thepattress.If an EI 161R or EI

166R(withremote TEST/HUSH)isbeinginstalled,attachthe “R”wire

fromthe EI152 (seethe EI152instruction) tothe terminalmarked “R”in

thepattress(seefigure1).IftheEI161RorEI166Ris beingusedwith a

manual callpoint MCP400orMCP400A thenconnect theRterminal to

thecallpoint(see figure2). Otherwisedonotconnectanythingto the”R”

terminal.

4.Connectthethree wires(“L”, “N”and“IC”)fromthe pattressto thecon-

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

be connected even ifit isa singlealarm installation.Connectthe earth

wire(ifpresent) fromthe housewiringdirectlytothe terminalonthe

mounting plate.Replace the cover over the terminal wires.

Connect thewires tothe required relaycontacts forcontrolling theauxil-

iary device (the contactsare isolated and are rated at250VAC,5amps re-

sistive).If momentaryrelay operationis required,carefully and gently

slidethe yellow switchto the offposition with asmall screwdriver(see fig-

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

Note 1:A maximum of12 Smoke/HeatAlarm of thetypes specified may

beinterconnected tooneEI 128R unit.Whenone alarmsensesfire all in-

terconnected units will alarm and the relay will switch.

Note 2: An alarm with battery back-up willcontinue tooperate duringa

mains failure butwill not beable to switch therelay.(The relay requires

the 230 VAC to operate).

Note 3:Devices connected tothe relay contactsmustnot givea fire warn-

inguntilthe contactshaveswitchedfor atleast200mSec.(Thecontacts
