Mains Carbon Monoxide Alarm
Ei225EN
Mains CO Carbon Monoxide alarm with Built-in Pattress
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.

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 instructionsAlarm with Built-in Pattress
