The Apollo Orbis Marine ORB-HT-41017-MAR is a Class CR Heat Detector with Flashing LED. The Orbis ORB-HT-41017-MAR has an open-web casing which enables the air to flow freely across a thermistor which measures the temperature of the air every two seconds. A microprocessdor stores the temperatures, and then compares them with pre-set values to determine wheter the alarm level has been reached.
The Apollo Orbis Marine ORB-HT-41017-MAR is used in applications where smoke detectors are unsuitable. Preferably smoke detectors are used, because smoke detection provides an earlier warning of fire than heat detection. The heat detectors should be used when there is a danger of nuisance alarms from smoke detectors.
The ORB-HT-41001-MAR Orbis Marine CR Heat Detector is suitable for mounting on ORB-MB-00001-MAR Orbis Marine TimeSaver® Base. For higher water ingress protection, the 45681-217APO Deckhead Mounting Box can be used.
