Ei Professional Smoke Alarms and Smoke Detectors

Mains Powered Carbon Monoxide Alarms

Applications

The 225E Series mains powered alarms use a proven electrochemical cell type sensor which checks CO concentration every 50 seconds. Reaction to CO gas is fast and they recover quickly when CO is no longer present. All units are individually calibrated in CO gas to ensure accuracy and peak performance and they carry a lifetime 5 year guarantee.

The alarm circuitry is automatically monitored and warns if a fault develops. A Test/Hush button confirms that the horn and electronics are working and silences alarms caused by transient CO levels. The alarm will automatically sound again after 4 minutes if high levels of CO are still present. Additionally a memory feature records if CO has been detected whilst the occupier was away.

To assist landlords with multiple CO installations, testing with CO gas has been made mush easier with the Quick CO Test Mode feature. This reduces the waiting time for testing from as much as 5 minutes down to approximately 20 seconds per alarm, a significant time and cost saving on a large installation.

A built-in pattress with terminal block simplifies installation. The alarms can be surfaced wired without the need for a recessed junction box.

Installation

For full Installation and Siting Instructions please refer to the Use and Care Manual

The Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations

Do not locate the CO Alarm where it could be exposed to dripping, splashing or condensation(e.g. bathroom, above an electric kettle etc)

Install the CO Alarm in or near every room that contains a fuel burning appliance, particularly rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms

Install preferably on the ceiling (300mm from walls) in rooms with an appliance. Install between 1.85m to 3m horizontally from appliance. In rooms remote from the appliance install about 1.5 to 2m above floor level, at breath level

Regularly check that the green power light is on. The CO alarm will not work if the mains supply is off

Test the unit weekly by pressing the Test/Hush Button – the horn will sound

Immediately the unit is powered the red and amber lights will flash once to show they are operational

Trouble Shooting

Alarm does not work with the Test Button:

Check that the green mains power light is on. If it is off check the wiring, fuse, circuit breakers etc.

Hold the Test Button down for at least 5 seconds

Alarm beeps and amber light flashes every 45 seconds:

If the alarm beeps and the amber fault light flashes every 45 seconds, the CO sensor is probably defective. Press the Test/Hush button to reset the unit. If the beeping and the amber light flashing re-occurs after 5 minutes, the unit is defective

Alarm sounds for no apparent reason:

Ensure there are no fuel-burning appliances in the vicinity which could be leaking CO gas(e.g. even from next door)

Ensure there are no fumes in the area (e.g. paint, thinners, hair spray, chemical cleaners, aerosol sprays etc)

Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine running, heavy traffic, heavy air pollution, barbecue fumes etc)

Press the Test/Hush button to silence the alarm

If the unit continues to sound it is possibly defective and should be replaced. Please refer to the use and care manual for instructions
