The Discovery carbon monoxide (CO) fire detector contains a long-life electrochemical CO sensor. The sensing technology is fast, accurate and needs only very low power. It does not detect smoke particles or heat and are is not a universal replacement for smoke detectors.
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 not to be confused with CO detectors which are used to protect people against carbon monoxide poisoning.
Discovery fire detectors are effective for only certain types of fire, such as deep-seated, smouldering fires.
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.
