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).

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.

CO in Air (ppm) Inhalation Time (approx) and symptoms developed.

The maximum allowable concentration for continuous exposure

in any 8 hour period according to OSHA (Occupational Safety &

Health Association).

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.

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.
