Aico Ei129 User Instruction
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.
