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.

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

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

(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.

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).
