CO detectors donÃ¢â‚¬â„¢t live forever
ST. CHARLES, Ill.Ã¢â‚¬â€Concerned that many security and fire integrators may not realize that carbon monoxide detectors must be replaced periodically, and that some detectors on the market today do not send a signal when they need to be replaced, System Sensor on Nov. 28 issued a white paper outlining when and why system-connected CO detectors need to be replaced.
Compared to other life-safety equipment, Ã¢â‚¬Å“CO detectors are still relatively in their infancy,Ã¢â‚¬Â said System Sensor director of communications David George.
The gas sensor within a CO detector has a finite life span and, according to the governing UL standard (UL 2075), when it reaches what the industry calls its EOL (end of life) it should send a signal to the control panel, alerting the homeowner or commercial establishment that the CO detector needs to be replaced.
However, certain models on the market (not produced by System Sensor) have been grandfathered and are in use today, but do not send the EOL signal to a panel.
Richard Roberts, senior product manager for System SensorÃ¢â‚¬â„¢s Security Business Unit, said in a statement, Ã¢â‚¬Å“We wrote this paper because we wanted to emphasize the difference between system-connected CO detectors and system-connected smoke detectors.Ã¢â‚¬Â System Sensor wants to get the word out Ã¢â‚¬Å“so that expired CO detectors get replaced.Ã¢â‚¬Â
David George said System Sensor distributed the white paper to Ã¢â‚¬Å“security dealers and distributors and to select AHJs in those areas of the country where CO detector use is mandated [11 states in the country].Ã¢â‚¬Â
