C08MS
Carbon Monoxide detector –
Installation Instructions
1 General Information
Warning: the installation of this alarm should not be used as a substitute for proper
installation, use and maintenance of fuel burning appliances including appropriate ventilation
and exhaust systems. This CO (Carbon Monoxide) alarm is designed to protect individuals
from the acute effects of carbon monoxide exposure. It will not fully safeguard individuals
with specific medical conditions. If in doubt consult a medical practitioner.
This alarm should be installed by a competent person.
•
Test the alarm weekly by pressing the test button.
•
The average life span of the alarm is 6 years.
•
Do not fit alarm until all building work is completed to avoid getting it dirty.
•
2 Working Principle
2.1 What is carbon monoxide?
Many people are killed each year, and many more suffer ill health from carbon monoxide
(CO) poisoning. CO is an invisible, odorless, 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 resulting in rapid damage to the heart and brain from oxygen
starvation.
High levels of CO in a building 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
The following symptoms are related to carbon monoxide poisoning and should be discussed
with all members of the building.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as "flu-like"
symptoms).
32318166-001 Rev. A
Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Unconsciousness, convulsions, cardio respiratory failure, death.
A high level of CO for a short period (e.g. 350 ppm CO for 30 minutes) will cause the
same symptoms, a slight headache, as a lower level for a longer time (e.g. 150 ppm for
90 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 that 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.

Health Association).
150 Slight headache after 1.5 hours.
200 Slight headache, fatigue, dizziness, nausea after 2-3 hours.
Frontal headaches within 1-2 hours, life threatening after 3 hours,

according to US Environmental Protection Agency.
Dizziness, nausea and convulsions within 45 minutes.
800
Unconsciousness within 2 hours. Death within 2-3 hours.
Headache, dizziness and nausea within 20 minutes. Death within
1,600
1 hour.
Headache, dizziness and nausea within 5-10 minutes. Death within
3,200
25-30 minutes.
Headache, dizziness and nausea within 1-2 minutes. Death within
6,400
10-15 minutes.
12,800 Death within 1-3 minutes.
Note: ppm = parts per million
2.3 What happens when your CO alarm detects carbon monoxide?
When the alarm detects potentially dangerous levels of CO, it flashes the red Pre-alarm light
immediately and then sounds a loud alarm if the CO persists. Table B below shows how the
CO alarm reacts to different levels of CO gas and exposure time.
