Alarm Trigger Module

Connects to Sprinkler & EN54 Fire Systems (24V)

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 Ei129 is designed to sound interconnected Ei Electronics

Mains Powered Alarms to give a fire warning. When the

external normally open contacts connected to it, close.

Its main applications are:

1. To trigger the Smoke/Heat/Fire Alarms to sound when a

Sprinkler System is activated.

2. To trigger all the Smoke/Heat/Fire Alarms in an apartment

to sound when the EN54 Fire System in the common areas

of the HMO* sense fire. This greatly increases the alarm

sound level throughout the apartment (this helps meet the

recommendations of the BS5839-6: 2004 Clause 13.2e)

which requires 85dB(A) at each bedroom doorway. (It can

also help meet the recommendations of Clause 13.2f) of

75dB(A) at each bed head where the fire risk assessment

warrants it).

* HMO - House in Multiple Occupancy

2. Installation Instruction

2.1 Installation of Ei129 under Ei Electronics Easi-Fit Alarms.

WARNING: Mains powered Alarm Trigger 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.

WARNING: First disconnect the mains from the circuit to be

used.

2.1.1 Choose a mounting position following the siting

instructions in the Smoke/Heat/Fire Alarm leaflet. Bring the

wiring from the external N/O contacts to this position. (With

an EN54 System an Input/Output Module is required and with

a Sprinkler System Changeover contacts should be specified

when it is being installed).

Caution:

The N/O contacts in the external device connected to the

Ei129, must be electrically isolated and rated for 230V~.

2.1.2 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

material from the selected knockout, making sure there is no

gap when mated with ducting / conduit. There are three

knockouts – two on the sidewall and one on the rear. (Do no

use the knockout next to the circuit board as the wiring may

damage the components).

2.1.3 Screw the Ei129 Module to the ceiling after first

removing the required knockout and bring the house wires

through it (see Figure 1). If the contact knockout is being

used, seal around the wires with silicone or similar to prevent

air draughts affecting the smoke or heat entering the alarm.

2.1.4 Connect the wires from the alarms (L – Live, N –

Neutral, and IC – Interconnect) to the terminal block on the

Ei129 Module as shown in Figure 1. Make the wiring

connections as shown in Figure 2.

2.1.5 Connect the two wires from the external N/O contacts to

the “Contacts In” terminals.

2.1.6 Connect the three short wires (“L” Brown, “N” Blue and

“IC White) from the Ei129 Module to the connector block on

the Smoke/Heat/Fire Alarm Easi-Fit Mounting Plate. Connect

the earth wire (if present) from the house wiring directly to the

terminal on the Easi-Fit Mounting Plate (see relevant

Smoke/Heat/Fire Alarm instructions). Replace the cover over

the terminal wires on the mounting plate.

2.1.7 Screw the Mounting Plate to the Ei129 Module Base

pillars using the two screws supplied.

2.1.8 Slide the alarm on to the mounting plate.

2.1.9 Re-Connect the mains power – the green LED on the

alarm should be on. Check the alarms as per their instruction

manuals by pressing the test buttons.

NOTE: A maximum of 12 Smoke/Heat/Fire Alarms of the

types specified may be interconnected to one or more Ei129

Alarm Trigger Modules.

2.1.10 Trigger the external contacts (e.g. at the Sprinkler

System Control Panel or the EN54 Fire System Panel) and

check that all the Smoke / Heat / Fire Alarms sound.

2.2 Installation of Ei129 with Cover Plate Ei128COV

2.2.1 If it is not convenient to install the Ei129 Module under

an alarm and / or it is preferable to mount it near the external

contacts then it can be installed as described above on a

suitable wall or ceiling. An Ei128COV Cover Plate is needed

which must be purchased separately.

2.2.2 Connect the wires from the alarms (L – Live, N –

Neutral, and IC – Interconnect) to the terminal block on the

Ei129 Module as shown in Figure 1. Then connect the two

wires from the external N/O contacts to the “CONTACTS IN “

terminals.

2.2.3 Important: Now remove the three short sleeved wires

from the central terminal block on the circuit board on the

Ei129 as they are now not needed (see figure 1). This is

essential to prevent them shorting and damaging the alarms

or blowing fuses.
