(1) The CO Alarm will not work without good batteries - the
green power light must flash every minute. If the battery has
been drained the alarm will not give protection. Button test
the alarm on return from holidays and other long absences.
(2) Carbon monoxide must enter the unit for it to be detected.
There may be carbon monoxide in other areas of the house
(e.g. downstairs, in a closed room etc.) but not in the vicinity
of the CO Alarm. Doors, air draughts and obstructions can
prevent the CO reaching the Alarm. For these reasons we
recommend CO Alarms are fitted both near and in bedrooms,
particularly if bedroom doors are closed at night. Additionally
in rooms where members of the household spend alot of their
time and in rooms with potential sources of CO gas.
(3) The CO Alarm may not be heard. The sound output is loud,
but it may not be heard behind a closed door or if it is too far
away. The Alarm may not wake up somebody who has taken
alcohol or drugs. The alarm sound may be masked by other
sounds such as a T.V., stereo, traffic noise etc. Fitting CO
Alarms on either side of closed doors will improve their
chance of being heard. This CO Alarm is not designed for
people with impaired hearing.
(4) CO Alarms don't last indefinately. CO Alarms are sophisti-
cated electronic devices with many parts. Although the
alarm and its component parts have undergone stringent
tests, and are designed to be very reliable, it is possible that
parts can fail. Therefore, you should test your CO Alarm
weekly.
(5) The entire CO Alarm must be replaced after 5 years.
Check
the “replace by date”
on the outside of the unit.
(6) CO Alarms are not a substitute for insurance. Householders
are responsible for their own insurance. The CO Alarm
warns of increasing CO levels, but we do not guarantee that
this will protect everyone from CO poisoning.
(7) CO Alarms are not suitable as early warning Smoke Alarms.
Fires can produce carbon monoxide, but the response char-
acteristics of these CO Alarms are such that they would not
give sufficient warning of fire.
Smoke Alarms must be fitted to give early warning of fire.
(8) The CO Alarm does not detect the presence of natural gas
(methane), bottled gas (propane, butane) or other combus-
tible gases. Fit combustion gas alarms to detect these.

WARNING:
APPARATUS CONFORMING TO THE BS 7860 :
1996 STANDARD MAY NOT PROTECT PEOPLE WHO ARE
AT SPECIAL RISK FROM CARBON MONOXIDE EXPOSURE
BY REASON OF AGE, PREGNANCY OR MEDICAL CONDI-
TION. IF IN DOUBT, CONSULT YOUR MEDICAL PRACTITIO-
NER. A CARBON MONOXIDE DETECTOR IS NOT A
SUBSTITUTE FOR A SMOKE ALARM OR A COMBUSTIBLE
GAS DETECTOR.
Follow these guidelines to reduce the risk of carbon monoxide
poisoning.
(1)
Know and look for tell-tale signs that carbon monoxide may
be present, they include:
- The CO Alarm warning of abnormal levels.
- Staining, sooting or discolouration on or around appliances.
- A pilot light frequently going out.
- A strange smell when an appliance is working.
- A naked gas flame which is yellow or orange instead of the
normal blue.
- Family members (including pets) exhibiting the “flu-like”
symptoms of CO poisoning described in section 2.2 pg 3.
If any of these signs are present get the appliance checked out
by an expert before further use. If family members are ill get
medical help.
(2)
Choose all appliances and vehicles which burn fossil fuels
such as coal, oil, natural/bottled gas, paraffin, wood, petrol,
diesel, charcoal etc. with care, and have them professionally in-
stalled and regularly maintained.
(3)
These appliances must “breathe in” air to burn the fuel properly.
Know where the air comes from, and ensure vents/air bricks etc. re-
main unobstructed (particularly after building work).
(4)
The appliances must also “breathe out” the waste gases (in-
cluding the CO) - usually through a flue or chimney. Ensure
chimneys and flues are not blocked or leaking, and get them
checked every year. Check for excessive rust or cracks on ap-
pliances and pipework.
(5)
Never leave your car, motor bike or lawnmower engine run-
ning in the garage with the garage door closed. Never leave the
door from the house to the garage open if the car is running.
(6)
Never adjust your own gas pilot lights.
(7)
Never use a gas cooker or a barbecue for home heating.
(8)
Children should be warned of the dangers of CO poisoning
and instructed never to touch, or otherwise interfere with the CO
Alarm. Do not allow small children to press the test/hush button
as they could be subjected to excessive noise when the unit
alarms.
(9)
Leaving windows or doors slightly open (even a few inches)
will significantly reduce the risk of high levels of CO occurring.
The high levels of draught-proofing in modern houses reduces
ventilation and allows dangerous gases to build up.
(10)
Install CO Alarms in all areas recommended in this leaflet.
(11)
Recognise that CO poisoning may be the cause when fam-
ily members suffer from “flu-like” symptoms when at home, but
feel better when they are away for extended periods.
Power
Three Alkaline AA type batteries (supplied)
Sensor
Electro chemical cell CO sensor
Alarm
85dB(A) at 3m
Red light flashes (every 2 seconds) with
about 150ppm CO and flashes faster
(every ½ second) with about 350ppm CO.
Response Time
At 150ppm between 10 & 30 minutes
At 350ppm less than 6 minutes
(As required by BS7860 1996)
Test / Hush & Alarm
Memory Button
Test:
Tests electronics & horn
Hush:
Pressing button when it is sensing
150ppm CO will silence the unit for about 5
minutes. Will only silence unit once. At
350ppm unit cannot be silenced.
CO Alarm Memory (
Ei
205 only):
Pressing the test button indicates if the unit
has sensed CO since reset, as follows:
1. Horn on and Green light flashing - has
not detected CO
2. Horn on and Red light flashing every 2
seconds - has detected 150ppm CO
3. Horn on and Red light flashing every ½
second - has detected 350ppm CO
Reset memory
by holding down the test
button until the green light flashes (nor-
mally takes 20 seconds) or disconect the
battery for 10 seconds
Self Diagnostics
Amber light flashes simultaneously with
horn beep every minute if a fault is found.
