1. IMPORTANT INFORMATION
WARNING: The Alarm should be permanently wired to the mains by a qualified electrician in accordance
with IEE wiring regulations (BS7671).
Install a Carbon Monoxide (CO) Alarm in every room that contains a fuel burning appliance,
particularly rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms.
In rooms with an appliance, install (preferably) on the ceiling (300mm from walls and between 1m
to 3m horizontally from appliance). In rooms remote from the appliance install at breathing level,
where the light indicators can be seen.
Regularly check that the green power light is on, so that rechargeable back-up cells will remain fully
charged. Important: The CO Alarm will not work if the mains supply is off and the rechargeable
cells are depleted.
Test the unit weekly by pressing and holding the Test/Hush button. The horn will sound.
Replace sensor module after 5 years operation (see page 23).

WHAT TO DO WHEN THE ALARM SOUNDS:
(1) Open the doors and windows to ventilate the area.
(2) Turn off all fuel appliances where possible. (The alarm can be silenced immediately by
pushing the Test/Hush button).
(3) Evacuate the property leaving the doors and windows open.
(4) Get medical help immediately for anyone suffering the effects of Carbon Monoxide
poisoning (headache, nausea), and advise that Carbon Monoxide poisoning is suspected.
(5) Ring your gas or other fuel supplier on their emergency number. Keep the number in a
prominent place.
(6) Do not re-enter the property until the alarm has stopped. (If the alarm has been silenced
by pressing the Test/Hush button, wait at least 5 minutes. The alarm will then check that the
CO has cleared).
(7) Do not use the fuel appliances again until they have been checked by an expert. In the
case of gas appliances this must be a Registered Gas Installer.
When the CO Alarm detects abnormal levels of CO (above 50ppm CO) the red light starts to flash
and the horn will sound within 90 minutes. At higher levels of CO the alarm will turn on sooner (see
Table B - page 8).
The CO Alarm will automatically reset once the CO has cleared. Pressing the Test/Hush button will
silence the CO Alarm immediately (below 300ppm CO). If CO is still present the red light and horn
will turn on again after about 4 minutes.

The CO Alarm is no substitute for keeping chimneys and flues clear and in good condition, and all of your
appliances serviced regularly according to the manufacturer’s instructions.
Do not fit alarm until all building work is completed to avoid contamination.
2. CARBON MONOXIDE - THE SILENT KILLER
2.1 WHAT IS CARBON MONOXIDE ?
Congratulations on becoming the owner of an Ei Carbon Monoxide Alarm. This will help protect you and
your household from the dangerous effects of Carbon Monoxide - The Silent Killer. Many are killed each
year, and many more suffer ill health from Carbon Monoxide (CO) poisoning (CO is the chemical symbol,
indicating the molecule has one carbon atom and one oxygen atom). CO is an invisible, odourless, tasteless
and extremely toxic gas. It is produced by appliances and vehicles burning fuels, such as coal, oil,
natural/bottled gas, paraffin, wood, petrol, diesel, charcoal etc. CO is absorbed by red blood cells in the
lungs in preference to oxygen - this results in rapid damage to the heart and brain from oxygen starvation.
High levels of CO in a house can be caused by:
•Incorrectly or poorly installed fuel-burning appliances.
•Blocked or cracked chimneys/flues.
•Blocked vents or draught-proofing which makes areas with fuel burning appliances or fireplaces airtight.
•Engines of cars, lawnmowers etc. left running in confined spaces.
•Portable paraffin or gas heaters in badly ventilated rooms.
2.2 SYMPTOMS OF CARBON MONOXIDE POISONING
Most people know that high levels of CO are harmful, however the period of exposure is also important.
?

B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM Page 6

A low level for a long period (e.g. 150 ppm for 90 minutes) can cause the same symptoms (a slight
headache) as a high level of CO for a short period (e.g. 350 ppm CO for 30 minutes). Table A shows how
exposure to different concentrations of CO generally affects people.
Many cases of reported Carbon Monoxide poisoning indicate that while victims are aware they are not
well, they become so disorientated they are unable to save themselves by either leaving the building or
calling for assistance. Young children and household pets may be the first affected.
Table A: Effects of Carbon Monoxide Poisoning
35 The maximum allowable concentration for continuous exposure in any 8 hour period according to OSHA *.
150 Slight headache after 1.5 hours.
200 Slight headache, fatigue, dizziness, nausea after 2-3 hours.
400 Frontal headaches within 1-2 hours, life threatening after 3 hours, also maximum parts per million in flue gas
(on an air free basis) according to US Environmental Protection Agency.
800 Dizziness, nausea and convulsions within 45 minutes. Unconsciousness within 2 hours. Death within 2-3 hours.
1,600 Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
3,200 Headache, dizziness and nausea within 5-10 minutes. Death within 25-30 minutes.
6,400 Headache, dizziness and nausea within 1-2 minutes. Death within 10-15 minutes.

2.3 WHAT HAPPENS WHEN YOUR CO ALARM DETECTS CARBON MONOXIDE ?
When the Alarm detects potentally dangerous levels of CO, it flashes the red alarm light and then sounds
a loud alarm if the CO persists. The digital display (Model Ei261DENRC only) indicates the CO level in
parts per million (ppm) CO.
Table B below shows how the CO Alarm reacts to different levels of CO gas and exposure time. At higher
levels of CO the alarm turns on sooner. The rate of flashing of the red light indicates the level of CO.
Table B: CO Alarm Response
* unless it has been in alarm (see 2.4 CO Alarm Memory overleaf)
If your CO Alarm sounds follow the instructions on page 5.
When ventilation is provided by leaving windows and doors open, the CO build up may have
dissipated by the time help arrives and the alarm may have stopped sounding. Although your problem
may appear temporarily solved, it is crucial that the source of the CO is determined and appropriate
repairs made.

NEVER IGNORE THE ALARM
Pre-Alarm: When the alarm detects over 50ppm CO the red light flashes every 2 seconds. This helps
locate CO leaks as the unit gives an indication straight away (without this feature the CO level would need
to be at 50ppm CO for 90 minutes for the horn to sound). Note the Pre-Alarm signal may be triggered by
CO coming for example, from cooking with gas, from car engines or from nearby barbecues. This is
usually not a concern unless the Pre-Alarm signal persists until the alarm sounds and the CO source is
unknown.
Note: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are released nearby.
2.4 CO ALARM MEMORY
When the Test button is pressed the horn will sound, and the red light will only flash if the unit has
previously detected CO and been in alarm. The flash rate indicates the level of CO detected as below:-
- Red light is Off – No CO detected since reset or power up.
- Red light flashes 2 times (in 2 seconds) every 40 seconds - 50 ppm CO detected for approximately
90 minutes since reset or power-up.
- Red light flashes 4 times (in 2 seconds) every 40 seconds - 100 ppm CO detected for approximately
40 minutes since reset or power-up.
- Red light flashes 8 times (in 2 seconds) every 40 seconds - 300 ppm CO detected for approximately
3 minutes.
When the Test button is held, the digital display on the Ei261DENRC model shows the previous peak
reading. This tells you if the unit has detected CO in your absence and helps to detect and locate leaks,
monitor premises etc.
Reset Memory by holding down the Test button for over 20 seconds until the red light stops flashing.
Cover the horn with a cloth to muffle the alarm during this time.
Please note that the memory will also be reset when the unit is removed from the mounting plate.

3. ALARM POSITIONING
3.1 IDEALLY A CARBON MONOXIDE (CO) ALARM SHOULD BE INSTALLED IN:
- Every room containing a fuel burning appliance
- Remote rooms where occupants spend a considerable amount of time
- Every bedroom
However if the number of CO Alarms is limited, the following points should be considered when deciding
where best to fit the alarm(s)
- If there is an appliance in a room where people sleep, place a CO Alarm in this room
- Locate a CO Alarm in a room containing a flueless or open-flued appliance
- Locate a CO Alarm in a room where the occupant(s) spend most of their time (e.g. living room)
- In a bedsit, the CO Alarm should be placed as far away from the cooking appliance as possible, but
near to where the occupant sleeps
- If the appliance is in a room not normally used (such as a boiler room) the CO Alarm should be placed
just outside the room so that the alarm will be heard more easily
3.2 UNSUITABLE LOCATIONS
Do not place the CO Alarm in any of the following areas
- In the immediate vicinity of a cooking appliance
- Outside the building
10
B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM Page 10

- In an enclosed space (e.g. in or below a cupboard)
- In a damp or humid area
- Directly above a sink or cooker
- Next to a door, window, air vent or anywhere that it would be affected by draughts
- Next to an extractor fan
- Where it would be obstructed, e.g. by curtains or furniture
- In an area where the temperature could drop below –10°C or rise above 40°C
- Where dirt or dust could block the sensor
- Where it could be easily knocked or damaged, or where it could be accidentally turned off or removed
- In a bathroom or other areas where the CO Alarm may be exposed to water splashes, dripping or
condensation (e.g. above an electric kettle)
- Near paint, thinners, solvent fumes or air fresheners
3.3 IF LOCATING THE CO ALARM IN A ROOM WITH A FUEL BURNING APPLIANCE (see Figure 1)
- If it is mounted on a wall, it should be located at a height greater than the height of any door or window
but still be at least 150mm from the ceiling
- If it is mounted on the ceiling it should be at least 300mm from any wall or light fitting
- The CO alarm should be a horizontal distance of between 1m and 3m from the potential CO source
11
B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM Page 11

- If there is a partition in the room, the CO Alarm should be located on the same side of the partition as
the potential source
- In rooms with sloped ceilings, the CO Alarm should be located at the high side of the room (see Figure 3)
3.4 IF LOCATING THE CO ALARM IN A BEDROOM OR IN ROOMS REMOTE FROM A FUEL
BURNING APPLIANCE (see Figure 3)
- Mount the CO alarm relatively close to the breathing zone of the occupants
Whatever position is chosen make sure it is possible to view the three light indicators, when in the
vicinity of the alarm.

4. INSTALLATION
The Alarm is designed to be permanently
mounted, using its own built-in terminal
block to connect it to the mains wiring. The
mounting plate can be screwed directly to
the ceiling/wall. Alternatively it can be
screwed to a standard junction box (BS
4662 single gang accessory box). The alarm
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
the actual alarm itself 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
sensor and cause problems, it will also
invalidate the guarantee). If it must be
installed, cover it completely, particularly
around the edges, with a suitable
covering, 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 an insulation tester on the alarm.
Do not use the CO Alarm on an intermittent basis, or as a portable detector for the spillage of
combustion products from fuel burning appliances or chimneys.
Mains operated Alarms should be installed and interconnected by a qualified electrician in accordance
with the Requirements for Electrical Installations published by the Institution of Electrical Engineers (as
BS7671). Failure to install this Alarm correctly may expose the user to shock or fire hazards.
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.
INSTALLATION PROCEDURE
1. Select a location complying with the advice in the previous section (see pages 8-12).
2. Disconnect the AC mains supply from the circuit that is going to be used to power the Alarm.
3. The house 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 - If you are only installing one alarm do not connect any cable to the IC terminal.
See page 19 for information on interconnecting.
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.
16
B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM Page 16

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.
Note: 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.
4. Lift off the wiring cover as shown in Figure 5 overleaf.
5. If the mains wires are being brought along the surface, conduit can be inserted into the top and/or
bottom of the mounting plate.
(a) position the mounting plate, so that the cable conduit is as shown in Figure 5 overleaf.
(b) Carefully cut around the knockout on the outside wall so the conduit fits. (Note: to comply with
the BS EN 60529, IPX2D protection rating, seal around conduit with silicone rubber or similar to
prevent water entering).
6. If the mains wiring is recessed, bring the wiring through the rear hole in the mounting plate as shown
in Figure 6.
7. 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 CO gas entering the alarm. If the hole is not closed off by the gasket
it should be sealed with silicone rubber or equivalent.
8. Replace the wiring cover.
9. Carefully line up the unit on the base and slide on.
10. Press the Test/Hush button for 10 seconds. The horn will sound. Check that any interconnected
alarms also sound within this period.
17
B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM Page 17

11. Connect the mains power to the alarm circuit. Check the green light is on.
The CO Alarm is now fully operational and will provide protection against a build up of Carbon
Monoxide gas 70 seconds after it is connected to the mains supply.
12. The unit may be tamperproofed further by removing the knockout in the sidewall of the mounting plate
(as shown in Figure 4) and inserting the self tapping screw (3mm diameter, 12mm long) after the unit
is on the mounting plate.

4.1 INTERCONNECTING
With interconnected alarms, when one unit detects CO all units alarm. All horns will sound but only units
detecting CO will flash their red lights.
A maximum of twelve Ei261ENRC/261DENRC CO Alarms may be interconnected along with an
Ei128RBU & Ei128COV relay module (see “ACCESSORIES” on page 32).
Alternatively, up to twelve Ei261ENRC /Ei261DENRC CO Alarms and Ei161RC/Ei164RC/Ei166RC
Smoke/Heat Alarms may be interconnected provided an Ei1529RC Remote Control is used in the
system (see “ACCESSORIES” on page 32).
Do not connect these Alarms to any other model produced by another manufacturer, or to any
other model of Ei Alarm, apart from those listed above. Doing this may damage the Alarms and could
result in a shock or fire hazard.
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 (820 ft) of wire can be used (maximum resistance between detectors 50
Ohms). Connect as shown in Figure 7.
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 etc.
If interconnected CO and Smoke/Heat Alarms are all sounding, the LOCATE switch on the Ei1529RC
Remote Control should be pressed. This will just leave the alarm that triggered the system sounding.
This is very important to determine because the actions to take in each situation are very different.
In the case of CO the premises should be fully ventilated by opening doors and windows.The user should
call the gas supplier etc.
In the case of fire, doors and windows should be closed to slow the spread of fire. The user should call
the fire brigade etc.
5. TESTING
1. Regularly check that the green mains power light is on. The unit cannot detect CO if the mains power is
off and the rechargeable battery back-up is depleted. (If it is off check circuit breakers, fuses, wiring etc).
2. Test the unit weekly by pressing the Test/Hush button. Hold the Test button (for up to 10 seconds) until
the horn sounds for over 5 seconds. This will help to familiarise you and your family with the distinctive
on-off sound of the CO Alarm. This test checks that the electronics and horn are working correctly. If units
are interconnected, button test each unit in turn and check all interconnected units alarm. (If the red alarm
light flashes when the button is pressed, see 2.4 “CO ALARM MEMORY” on page 9). Alternatively, if an
Ei1529RC Remote Control is in the system the unit can be tested by pressing the Test switch on the
Ei1529RC. This is equivalent to pressing the Test button on the Alarm. For further information see
“ACCESSORIES” on page 32.
3. If the Alarm gives a short beep and the amber fault light flashes every 40 seconds it means the self-
