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.
