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.
