1.2 Alarm Removal
LOCATE REMOVAL SLOT
LOCATE THE ARROW ON THE FRONT FACE OF THE ALARM.
THE SLOT IS LOCATED DIRECTLY ABOVE THE ARROW.
INSERT SCREWDRIVER
INSERT A FLAT-BLADED SCREWDRIVER HORIZONTALLY
ABOUT 10mm INTO THE CENTRE OF THE REMOVAL SLOT
SLIDE ALARM OFF BASE
WITH THE SCREWDRIVER STILL INSERTED, PUSH THE LOWER
HALF OF THE ALARM AWAY FROM THE SCREWDRIVER, IN THE
DIRECTION OF THE ARROW ON THE COVER
HOLD THE LOWER HALF OF THE ALARM AND REMOVE FROM
THE BASE PLATE BY LOWERING THE ALARM TOWARDS
THE FLOOR.

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.
