1. Introduction

The Ei140e series is supplied with an Easi-Fit base that

allows very quick and simple installation of the Smoke

Alarm, combined with simple detector head removal

and replacement. The Easi-Fit base automatically

connects both mains power and battery as the detector

head slides on to the Easi-Fit base.

Up to 12 Smoke/Heat Alarms can be interconnected so

that when one senses fire all the units alarm.

Interconnection can be achieved by hardwire or through

an RF mounting plate, the Ei168RC.

All Alarms feature a combined test/hush button.

* Temperature and Humidity conditions are for normal operation and

storage. The Alarms will function outside these ranges as required

by the specific product standards. Extended exposure to conditions

outside these ranges can reduce product life. For advice on

prolonged operation outside these range consult the manufacturer.

2.1 Important Safety Instructions

WARNING: Mains operated Alarms must be installed

and interconnected by a qualified electrician in

accordance with the local appropriate Regulations

for Electrical Installations. Failure to install this Alarm

correctly may expose the user to shock or fire hazards

and damage the product.

The Alarm is designed to be permanently mounted,

using its own built-in terminal block to connect it to the

mains. The mounting plate can be screwed directly to

the ceiling. Alternatively, it can be screwed to a standard

junction box (BS 4662 single gang accessory box). The

Alarm must not be exposed to dripping or splashing.

There are important markings on the underside of the

Alarm.

WARNING: An all-pole mains switch shall be

incorporated in the electrical installation of the building.

WARNING: Batteries (battery pack or batteries

installed) shall not be exposed to excessive heat such

as sunshine, fire or the like.

ATTENTION: Alternative Energy Sources - (Wind,

Solar, UPS etc.)

This product is designed to be connected to a Pure or

True Sine Wave 230V AC supply.

If connecting to a power source that utilises an inverter,

e.g. PV solar panel, the Total Harmonic Distortion (THD)

must be less than 5%. If in doubt, please check with the

manufacturer of the inverter. This also applies to battery

powered UPS (Uninterruptible Power Supply) inverters.

ATTENTION: Light Dimmer Circuits – The Alarms must

not be powered from a light dimmer circuit.

ATTENTION: Do not install Alarms in new or renovated

buildings until all work is completed.

ATTENTION: The Alarm must not be connected when

the house wiring insulation is being checked with high

voltages. i.e. Do not use a high voltage insulation tester

on the Alarm.

ATTENTION: The Alarm must be continuously powered

24 hours a day so it is important that it is not on a circuit

that can be turned off by a switch.

ATTENTION: (UK) BS 5839-6:2019 gives the following

recommendations regarding the mains supply to be

used in a Grade D system. The power supply for the

Alarms should be derived from the public electricity

supply to the dwelling. The mains supply to the Alarms

should take the form of either:

(a) an independent circuit at the dwelling’s main distribution

board, in which case no other electrical equipment

2. Installation

should be connected to this circuit (other than the

supply to a dedicated social alarm control unit); or

(b) a separately electrically protected, regularly used

local lighting circuit.

(See BS 5839-6:2019 for further information).

2.2 Where to Locate the Alarm?

The advice here follows the guidance in British Standard

BS 5839-6:2019 in general (for further information refer

to the standard).

The main reason for fitting Smoke/Heat Alarms in

dwellings is to ensure that when there is a fire, sufficient

early warning is given so that everybody can escape

safely. This means that the Smoke/Heat Alarms should

ideally be located near all potential sources of fires and

that the alarm should be heard throughout the house –

particularly in the bedrooms.

It is also important that nuisance/false alarms are minimised

to ensure the Alarms are not disabled or ignored.

A single Smoke Alarm will give some protection if it is

properly installed, but most homes will require two or

more to ensure that a reliable early warning is given.

For recommended protection you should put individual

Smoke Alarms in all rooms where fire is most likely to

break out (apart from the kitchen and bathroom).

BS 5839-6:2019 gives guidance on:

- how many Alarms to install

- what type of Alarm to use

- where to position Alarms

The above points will depend on the type of dwelling to

be protected and the level of fire risk.

Fire Risk Assessment

The ‘Grade’ and ‘Category’ of system that should

be installed depends on the fire risk. It is therefore

recommended that a Fire Risk Assessment is

undertaken. The Risk Assessment would be based on a

combination of probabilities:

- fire occurring

- injury or death to occupant

- system operating correctly with a fire

- early detection and warning to occupants in the event

of a fire

The greater the risks, the more comprehensive and

reliable systems needs to be.

LD (Life protection in Dwellings) Systems define the level

of fire protection required for households, depending

on the fire risk and regulations. Aico/Ei Electronics

recommends that an LD1 system be installed for

optimum protection.

Optimum Protection LD1: As LD2, but in addition

Smoke or Heat Alarms should be located in all rooms

and other areas of the dwelling.

(apart from toilets or bathroom)

Interconnect all Alarms

for dwellings where occupants may be at high risk (e.g. elderly)

for new or materially altered dwellings or existing dwellings

with poor structural fire precautions

for dwellings where occupants may be at high risk (e.g. elderly)

for new or materially altered dwellings or existing dwellings

with poor structural fire precautions

Basic Protection LD2: Smoke or Heat Alarms in all

rooms or areas that present a high fire risk to occupants.

(i) A Heat Alarm should only be used in a room adjoining

an escape route, in conjunction with Multi-Sensor

Fire Alarms or Smoke Alarms on the escape routes.

All the Alarms should be interconnected to ensure

the early warning will be heard.

(ii) Some Fire authorities (concerned with the slow

response of Heat Alarms) advise that Multi-Sensor

Fire Alarms or Smoke Alarms should be fitted in

living rooms. This is acceptable according to BS

5839-6:2019 provided there are clearly not going to

be problems with nuisance alarms. Fit Heat Alarms

only if nuisance alarms are very likely and it is

acceptable that a warning will only be given by the

Heat Alarm when there is a very significant flaming

fire in the room. If the door(s) and windows are not

closed to contain the fire and heat, it is extremely

unlikely that the Heat Alarm would respond before

a Multi-Sensor Fire Alarm or Smoke Alarm sited

outside in the corridor.

(iii) In enclosed kitchens with doors closed.

Improved Audibility

The effectiveness of a Category LD2 system can

be significantly enhanced if an additional Alarm

(interconnected) is installed in the master bedroom. This

will help ensure that a responsible person will quickly

be alerted to a fire and can arrange for an orderly

evacuation of children and other vulnerable occupants.

Grade D System

The mains powered Smoke and Heat Alarms with

battery back-up, covered by these instructions are

suitable for the requirements for a Grade D System.

A Grade D system is needed for:

- New or materially altered dwellings up to three-storeys,

with no floor over 200m2in area.

- Existing dwellings with poor structural fire precautions,

up to three storeys, with no floor over 200m2in area.

- Houses in Multiple Occupation (HMOs) of one or

two-storeys, with no floor over 200m2 in area.

- Individual dwellings units of two or more rooms in

HMOs.

Check that a Grade D system is adequate for the

dwelling into which the system is being installed.

2.4 Where in the Room?

The locations must comply with applicable building

regulations.

Ceiling Mounting

Hot smoke rises and spreads out, so a central ceiling

position is the preferred location. The air is “dead” and

does not move in corners, therefore Alarms must be

mounted away from corners. Fit the Alarm:

- At least 300mm away from walls. (see Figure 1).

- At least 300mm from any light fitting or decorative

object which might obstruct smoke / heat entering the

Alarm.

Fig.1

Wall mounting (Ei146e only)

If ceiling mounting is impractical, only the Ei146e Optical

Smoke Alarm may be mounted on a wall, provided that:

a) the top of the detection element is between 150mm

and 300mm below the ceiling (see Figure 2);

b) the bottom of the detection element is above the level

of any door openings;

Wall mounting should only be considered where close

spaced beams or similar obstructions may preclude

ceiling mounting. It is considered to be the responsibility

of the installer/client to determine if the presence of

asbestos in the ceiling material would make ceiling

mounting ‘impractical’.

Sloping Ceiling

With a sloping or peaked ceiling install a Smoke Alarm

within 600mm of the peak (measured vertically) and a

Heat Alarm within 150mm.

If the height of the peak is less than 600mm in the case

of Smoke Alarms or 150mm in the case of Heat Alarms,

it is regarded as being flat. (see Figure 3).
