EI Electronics have all types of carbon monoxide alarms. These range from standalone batter to mains wired alarms with indicator lights.
EI Electrics Battery & Mains
Some of these Ei electric batteries and mains such as alkaline battery backup are the best because they respond quickly to flaming fires. They have a distinctive ionization smoke chamber that is long-lasting. They have hush buttons to control false alarms. They are designed to fit the EI mains powered smoke and heat alarms. These batteries have two separate mains and LEDs for warning. They are cost-effective and easy to fit. They are usually supplied with dust covers and a five-year warranty guarantee. These Ei batteries are supplied while connected to avoid errors during installation. The carbon monoxide alarms are installed, especially in rooms that have fuel-burning utensils. The specific places in homes where these alarms can be fit are in the kitchens, living rooms, and bedrooms. This allows the alarms sensor to detect any CO; therefore, for a proper response, the batteries should always be changed after the specified period or when a condition develops for desirable results and home safety. If all your appliances are electric, then carbon monoxide is not essential to have in your compound.

TYPES OF ALARMS
There are mainly four types of smoke alarm currently on the market – ionisation, optical (also described as photo electronic), heat and combined.
IONIZATION
These are the cheapest and cost very little to purchase. They are very sensitive to small particles of smoke produced by fast flaming fires, such as paper and wood, and will detect this type of fire before the smoke gets too thick. They are marginally less sensitive to slow burning and smouldering fires which give off larger quantities of smoke before flaming occurs. They can also be too over-sensitive near kitchens.
OPTICAL
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
COMBINED SMOKE & CARBON MONOXIDE ALARM
Alarms that combine both smoke detection and CO alarm protection in one ceiling-mounted unit. This reduces costs and takes up less of your living space.
COMBINED OPTICAL SMOKE & HEAT ALARMS
These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
HEAT ALARMS
They detect the increase in temperature from a fire and are insensitive to smoke. They can therefore be installed in kitchens. They only cover a relatively small area of a room, so potentially several heat alarms need to be installed in a large kitchen.
Important information regulations
Carbon monoxide alarms
A carbon monoxide alarm depends on a sensing element the output of which changes in the presence of carbon monoxide. It has a limited life span and may become obsolete even though the electric circuitry
remains functioning which is why an end of life alarm is required. The carbon monoxide alarm may give an end of life
indication in accordance with the following criteria:
1. Powered by a non replaceable (sealed) battery unit where the battery life does not exceed the life of the sensor;
2. Powered by mains electricity (not plug in type) where a timer is included to indicate the end of life of the unit;
3. Powered by a replaceable battery where the timer is included to indicate the end of life of the unit Carbon monoxide alarms should:
a. Comply with I.S. EN 50291-1:2010/A1:2012; and
b. Incorporate a visual and audible indicator to alert users when the working life of the alarm is due to pass; and
c. The manufacturer should have a third-party certification confirming compliance with the standard.
