2. MULTI-SENSOR FIRE ALARM FEATURES
The state of the art EI2110 Multi-Sensor Fire Alarm, with its Heat enhanced Optical
Smoke Sensor, has a significantly improved performance as described below.
1. Faster Response to a wider range of fires.
The combination of the ultra fast temperature sensing thermistor and the high
performance optical sensor within the unit, enhances the fire sensing performance
such that the unit detects all the 7 different Test Fires (TF) specified in the standard
BS ISO 7240-15: 2004. These Test Fires are designed to produce different levels of
smoke/heat and as such are a good test of the units performance to the different fires
that could possibly occur in the home.
2. Reduced Nuisance Alarms.
The unit can tolerate up to 50% higher levels of cooking fumes and steam when
compared with normal optical sensor alarms.
3. Increased Longevity and Ruggedness.
The unit can tolerate up to 100% more dust and contamination build-up when
compared with normal optical sensor alarms. This is due to the unique automatic
DUST* compensation built into the unit which monitors the contamination in the smoke
sensing chamber and adjusts the alarm trigger point accordingly.
*DUST – Dust Ups Sensor Threshold.
Additionally, the optical sensor chamber features a fine mesh insect screen that is
bonded to the plastic of the chamber. This significantly improves immunity to insect
contamination.

4. Replace Alarm Indicator.
If the optical sensor chamber becomes very heavily contaminated, the amber fault
light will flash once every 40 seconds to inform the user. Action can then be taken to
replace the unit, long before the contamination causes nuisance alarms.
5. Alarm Memory.
After a the unit has gone into alarm, the red alarm light will flash twice (1 second apart)
every 40 seconds to indicate that the unit has alarmed in the previous 24 hours.
Additionally, pressing the Test/Hush button on this unit will cause it to emit short, rapid
beeps instead of the normal alarm sound. Both these features allow easy
identification, for example, of the source of nuisance alarms during the night.
6. Single Person Interconnect Test
Pressing and holding the Test button on the unit causes the alarm to sound. On
releasing the test button, the alarm will immediately cease but all interconnected
alarms will continue to sound for 3 seconds. This allows easy audible check of alarm
interconnection.
3. 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).
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 7

The Multi-Sensor Alarm can be installed for superior performance anywhere the
regulations specify an Optical Smoke Alarm or an Ionisation Smoke Alarm.
(The Ei2110 Multi-Sensor Fire Alarm can also be used and interconnected with an
Ei166RC Optical Smoke Alarm or an Ei161RC Ionisation Smoke Alarm if necessary).
The advice here follows the guidance in British Standard BS 5839-Part 6:2004 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 units are
not disabled or ignored.
BS 5839-Part 6:2004 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.
8
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 8

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.
3.1 Categories of System
There are three Categories of LD systems for Life protection in Dwellings that can be
installed, depending on the fire risk and regulations.
Please see following pages for detailed information.

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 Category LD2 and LD3 systems 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.
3.3 Grade D, E & F Systems
The mains powered, with battery back-up, Multi-Sensor Fire Alarm covered by these instructions
will meet the requirements for a Grade D Systems (and exceed Grades E & F).
A Grade D system is needed for:
- new or materially altered dwellings up to three-storeys, with no floor over 200m2 in area
- existing dwellings with poor structural fire precautions, up to three storeys, with no floor over
200m2 in area
- Houses in Multiple Occupation (HMOs) of one or two-storeys, with no floor over 200m2 in area
14
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 14

- 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.
4. 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 unit:
- 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.

Figure 1 Figure 2
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 15

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 unit.
4.1 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 Heat Alarms in any of the following areas:
• Bathrooms, shower rooms or other rooms where the unit may be triggered by steam or
condensation.
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 unit.
• 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 unit.
16
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 16

• 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 unit (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 unit at least 1m from dimmer controlled lights and wiring as some dimmers can cause
interference.
• Locate the unit at least 1.5m and route wiring at least 1m away from fluorescent light fittings as
electrical “noise” and/or flickering may affect the unit. Do not wire into the same circuit as
fluorescent lights or dimmers.
• 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.
5. 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.
IMPORTANT PRECAUTION: Do not install alarms in new or renovated buildings
until all work is completed (including floor coverings) and the building has been
17
B16350-R0-Ei2100 SERIES-U&C.qxd 18/9/08 3:46 PM Page 17

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
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: 2004 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: 2004 for further information)

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 page 23 & 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.
• 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 on page 23).
