CO Detectors
All carbon-based materials in the smouldering, red ember stage of a fire can produce significant and easily detectable levels of carbon monoxide (CO). These levels can, therefore, be monitored in order to give an early warning of a fire.
CO fire detectors are not to be confused with CO detectors which are used to protect people against carbon monoxide poisoning. Exposure to CO at concentrations above 300 parts per million (ppm) can be lethal, causing death within minutes. Apollo do not produce this type of CO detector.
By contrast, CO fire detectors are electronic detectors that can indicate the outbreak of a fire by sensing the level of CO in the air. These detectors have an electrochemical cell which senses CO but not smoke or any other combustion products.
CO fire detectors are effective for only certain types of fire such as deep-seated, smouldering fires. Smoke detectors, however, will almost always give a better response to a fire that produces a rising plume of smoke.
After extensive tests, Apollo has concluded that a multisensor detector, using smoke and heat sensors, can offer a big reduction in false alarms compared with simple smoke detectors. At the same time, the multisensor can out perform the CO fire detector for most common fire types.
