1. Read This First

• 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.

• The Carbon Monoxide Alarm (CO Alarm) is powered up by carefully rotating it

onto the mounting plate which activates the on/off switch. The indicator lights

will immediately flash in sequence to show they are working. (For the Display

models, the LCD screen will briefly display all icons). Then wait 15 seconds after

connecting the power before button testing.

• The Power light is not illuminated during standby. This light will flash green

when the test button is pressed to indicate that power is present and Alarm is

functioning.

• Install a 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 ‘head height’, where the light indicators can be seen.

• Test the Alarm weekly by pressing and holding the test button for a few seconds.

• Replace Alarm when the “REPLACE UNIT BY” date has been reached. Check

the label on the side of the Alarm.

• 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 ?

Many people are killed each year, and many more suffer ill health from Carbon

Monoxide (CO) poisoning. 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 What happens when your CO Alarm detects Carbon Monoxide ?

When the Alarm detects potentially dangerous levels of CO, it flashes the red alarm

light immediately and then sounds a loud alarm if the CO persists. Table B-1 & B-2

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. If your CO Alarm sounds follow the instructions

in section 6. NEVER IGNORE THE ALARM !

2.3 Symptoms of Carbon Monoxide Poisoning

Table A

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.

12,800 Death within 1-3 minutes.

2.4 Pre-Alarm

When the Alarm detects over 43 ppm CO the red light flashes in accordance with

Table B-1 & B-2. This helps locate CO leaks as the CO Alarm gives an indication

straight away.

(Without this feature the CO level would need to be at 43 ppm CO for typically

72 minutes for an alarm sound to be given). 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.

The display models will display CO concentrations greater than 10ppm in

accordance with Table B-1 & B-2.

NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols

are released nearby.

2.5 CO Alarm Memory

The CO Alarm memory is an important feature of the CO Alarm where even if the

house is unoccupied during an alarm condition it warns the homeowner that the CO

Alarm has previously detected CO gas and been in alarm. The memory feature has

two operation modes:

- memory indication for 24 hour period after alarm.

- memory recall on demand

24 hour memory indicators: After alarm, the RED light will flash at different rates

every minute (approx) depending on the level of CO detected - see Table C.

Memory recall on demand: To review the memory status after initial 24 hours,

press and hold the test button, the red led will flash in accordance to Table C.

Display models will show the peak level of CO measured.
