2. How many Alarms to install
- Categories & Grades -
The ideal system would consist of Multi-Sensor Fire Alarms installed throughout the
dwelling apart from the kitchen which should have a Heat Alarm installed (Note:
Alarms should not be installed in toilets/bathrooms).
The Multi-Sensor Alarm can be installed for superior performance anywhere the
regulations specify an Optical Smoke Alarm or an Ionisation Smoke Alarm.
(The Ei2110e Multi-Sensor Fire Alarm can also be used and interconnected with any
Ei Electronics mains powered compatible Alarm if necessary).
The advice here follows the guidance in British Standard BS 5839-Part 6:2013 in
general (for further information see the BS standard itself).
The main reason for fitting 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 fire Alarms should ideally be located in all escape routes and in all
rooms that contain potential sources of fire. Another important consideration is 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.
BS 5839-Part 6:2013 gives guidance on:
- how many Alarms to install
- what type of Alarm to use
- where to position Alarms
6

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 are needed.
2.1 LD Systems
LD (Life protection in Dwellings) systems define the level of fire protection required for
households, depending on the fire risk and regulations. Ei Electronics recommends
that an LD1 system be installed for optimum protection.
Please see following pages for detailed information.

8
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)
Basic Protection LD2: Smoke or Heat Alarms in all
rooms or areas that present a high fire risk to occupants.
Heat Alarms located in:
(Heat Alarms must be within 5.3m of potential fire
sources)
each Kitchen
Smoke or Heat Alarms located in:
each Living room (i.e. most frequently used
daytime room)
Smoke Alarms located:
on each storey
every 7.5 m of hallways and escape routes
within 3m of all bedroom doors
(apart from toilets & bathrooms )

1Some Fire authorities (concerned with the slow response of Heat Alarms) advise that Smoke Alarms (or
Multi-Sensor Alarms) should be fitted. This is acceptable according to BS 5839-6 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 Alarm sited outside in the corridor.
2In enclosed kitchens with doors closed.
3Fast flaming fires generate considerable amounts of heat. The Multi-Sensor Fire Alarm has a heat
enhanced optical smoke sensor to improve the response of the sensor to these types of fires.
4Do not install in kitchens.
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.
2.3 Grade D System
The mains powered, with battery back-up, Multi-Sensor Fire Alarm covered by these instructions
will meet 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 200m2in 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.
10

3. Positioning Alarms
The locations must comply with applicable building regulations.
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. Place 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.
Note: Ceiling mounting is recommended - do not wall mount Alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install the Alarm 900mm from the highest point
measured horizontally (see Figure 2). This is because “dead air” at the apex may
prevent smoke from reaching the Alarm.

3.1 Locations To Avoid
DON’T place Multi-Sensor Fire Alarms in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other rooms where the Alarm may be triggered by
steam, condensation, normal smoke or fumes. Keep at least 6 metres away from sources of normal
smoke/fumes.
DON’T place Multi-Sensor Fire Alarms in any of the following areas:
• Places where the normal temperature can exceed 40°C or be below 4°C (e.g. attics, furnace
rooms, directly above ovens or kettles etc.) as the heat/steam could cause nuisance alarms.
• Near a decorative object, door, light fitting, window moulding etc., that may prevent smoke or
heat from entering the Alarm.
• Surfaces that are normally warmer or colder than the rest of the room (e.g. attic hatches).
Temperature differences might stop smoke or heat from reaching the Alarm.
• Next to or directly above heaters or air conditioning vents, windows, wall vents etc. that can
change the direction of airflow and cause rapid temperature fluctuations.
• In very high or awkward areas (e.g. over stairwells) where it may be difficult to reach the Alarm
(for testing, hushing etc.).
• Locate away from very dusty or dirty areas as dust build-up in the optical sensor chamber can
impair performance. It can also block the insect screen mesh and prevent smoke from entering
the chamber.
• Locate the Alarm at least 1m from dimmer controlled lights and wiring as some dimmers can
cause interference.
• Locate the Alarm at least 1.5m and route wiring at least 1m away from fluorescent light fittings
as electrical “noise” and/or flickering may affect the Alarm. Do not wire into the same circuit as
fluorescent lights or dimmers.
12

• Do not locate in insect infested areas. Small insects getting into the optical sensor chamber can
cause intermittent alarms. Insects and contamination on the heat sensor can increase its
response time.
4. Installation
The Alarm is designed to be permanently mounted, using it’s 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. It requires a current
of 60mA. The Alarm must not be exposed to dripping or splashing. There are important
markings on the underside of the Alarm.
Caution
Alternative Energy Sources - (Wind, Solar, UPS etc.)
This product is designed to be connected to a Pure or True Sine Wave 230 Vac 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.
Light Dimmer Circuits – The Alarms must not be powered from a light dimmer circuit.
IMPORTANT PRECAUTION: Do not install Alarms in new or renovated buildings
until all work is completed (including floor coverings) and the building has been
fully cleaned. The wiring can be installed when appropriate. (Excessive dust and
debris from building work can contaminate the optical sensor chamber or heat
sensor and cause problems. It will also invalidate the guarantee). If it must be
13

installed, first cover it completely, particularly around the edges, with a dust
cover (eg. with the elasticated cover supplied or a plastic bag), until all cleaning
is finished.
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.
WARNING: Mains operated Alarms should be installed and interconnected by a
qualified electrician in accordance with the Regulations for Electrical Installations
published by the Institution of Electrical Engineers (BS7671). Failure to install this Alarm
correctly may expose the user to shock or fire hazards.
WARNING: 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.
Note: BS 5839-6: 2013 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 a dedicated monitoring device installed to
indicate failure of the mains supply to the Alarms); or
(b) a separately electrically protected, regularly used local lighting circuit.
Alarms should be connected on a single final circuit, unless the means of interconnection is by radio
signals (e.g. RadioLINK). (See BS 5839-6: 2013 for further information).

4.1 Mounting & Wiring Alarms
1. Select a location complying with the
advice in previous sections (see pages
8-18).
2. Disconnect the AC mains supply from
the circuit that is going to be used.
3. Lift off the wiring cover as shown in
Figure 3.
The wiring must be connected to the terminal
block on the mounting plate as follows:
L: Live - connect to the house wires
coloured brown or marked L.
N: Neutral - connect to the house wires coloured blue or marked N.
IC: Interconnect - see Section 4.2 & Figure 6 for information on interconnection.
Note: Wiring must be installed in compliance with local regulations.
Warning: Mixing the Live and Neutral connections when interconnecting Alarms
will damage all the Alarms - ensure that the same colours are used throughout the
premises for Live, Neutral and Interconnect wires.
We strongly recommend that you check for the following before connecting the
Alarm:
• check for Live and Neutral using a two probe tester.
15

• check for Live using a neon tester.
• check that the Interconnect wire is NOT connected to Live, Neutral or Earth. Do not
use an Earth wire for the Interconnect line.
N.B. The Alarm does not need to be earthed. However the terminal marked is provided
for the convenience of the installer so that any copper Earth wire or cable coloured green &
yellow, can be safely terminated.
To interconnect Alarms connect all the IC terminals together as shown in Figure 4 (see
“Interconnecting Alarms” section).
4. If the mains wires are recessed, bring the wires through the rear hole in the
mounting plate as shown in Figure 4.
16
REMOVEABLE
TRUNKING DOOR FOR
Figure 4 Figure 5

If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is as shown in Figure 4.
(b) the mounting plate has a removable section, take it out to interface directly with
25mm trunking as shown in Figure 5. If interfacing to 16mm trunking carefully cut around
the marked section, leaving the top intact and replace the section. (If you are not using
surface wiring, the removable section must be left in place for electrical safety reasons).
There are two other positions which are also suitable for the surface wiring to enter
(and exit) the Alarm, one next to the removable section and another directly opposite.
5. Carefully align the mounting plate and screw into place. Connect the wires to the
terminal block. With recessed wiring, ensure the rear gasket seals around the edge of
the hole in the ceiling or wall. This is to prevent air draughts affecting the smoke/heat
entering the Alarm. If the hole is too large or the Alarm does not seal it, it should be
sealed with silicone rubber or equivalent.
6. Replace the wiring cover &carefully line up the Alarm on the base and slide on.
7. Press and hold the test/hush button for 10 seconds. The horn will sound. Check that
any interconnected Alarms also sound within this period. With the Multi-Sensor Alarm,
the test button sounds the local horn and on release this horn stops immediately, and
all the interconnected Alarms can then be heard in the distance as they will continue
to sound for a further 3 seconds.
8. Connect the mains power to the Alarm circuit. Check the green light on the front of
the Alarm is on.
9. Attach the ‘Smoke Alarm’ identification label provided to the distribution board to
identify the Alarm circuit.
17

10. Attach the ‘Mains Smoke / Heat Alarms’ label provided on or near the distribution
board and write in date installed and the number of Alarms on the circuit.
Ensure the Alarm operates correctly - see “TESTING & MAINTAINING YOUR
ALARM” section.
4.2 Interconnecting Alarms
Note: A maximum of twelve Ei2110e Multi-Sensor Fire Alarms can be interconnected
in an Ei Electronics Alarm system. (Note the Multi-Sensor Fire Alarm Ei2110e can also
be interconnected to Ei140RC / Ei160RC / Ei140e / Ei160e Series Smoke/Heat
Alarms if required). It can also be interconnected to Ei261ENRC / 261DENRC Carbon
Monoxide Alarms provided an Ei1529RC Remote Control Switch is incorporated in the
system. Make electrical connections as shown in Figure 6.
The Ei2110e Multi-Sensor Fire Alarm can also be RF interconnected to other RF
devices by installing an Ei100MRF RadioLINK+Module. See the User manual for the
Ei100MRF for further details on RF interconnection. The Ei2110e is also equiped to
work in a hybrid system (combination of hard-wired & RF interconnected devices).
Please note in a hybrid system containing Ei160e Series Smoke/Heat Alarms we
recommend using the Ei2110e as the hybrid link to the RF section of the system.
If you wish to connect more than twelve alarms contact your local helpline (see page 20).
Systems using more than 3 or 4 Alarms must be very carefully planned to ensure nuisance
alarms are not excessive. e.g. from cooking fumes or steam. The following is suggested:
• An Ei Electronics Remote Control Switch should be incorporated into the system and
be readily accessible to all occupants so that the source of an alarm can be quickly
identified.
18

• All Alarms must be cleaned and maintained regularly.
• A qualified person must be on call to quickly remove any nuisance Alarms (i.e. Alarm
with red light flashing rapidly) which are causing all the other Alarms to sound.
WARNING: Do not connect these Alarms to any other type of Ei Alarm (apart from
those listed above) or to any other model produced by another manufacturer. Doing
so may damage the Alarms and could result in a shock or fire hazard.
Wiring must be installed in compliance with local regulations.
In the UK it is recommended that the following coloured cores are used (for
example with triple flat 6243YH cable).
230V supply Brown
Neutral Grey - sleeved blue at terminations
Interconnect Black
In the Republic of Ireland consult the local regulations as they are different from the
UK regulations.
Figure 6
19

The interconnect wire (minimum 0.75mm2cable) must be treated as if it was Live. It
should be insulated and sheathed.
A maximum of 250 metres of wire can be used (maximum resistance between
detectors 50 Ohms).
Alarms should be interconnected only within the confines of a single family living unit.
If they are connected between different units there may be excessive nuisance alarms.
Everybody may not be aware that they are being tested or that it is a nuisance alarm
caused by cooking etc.
Ensure the Alarms operate correctly - see “TESTING & MAINTAINING YOUR
ALARM” section.
