The Apollo Discovery Marine 58000-400MAR is an analogue addressable heat detector, suitable for use on larger vessels. The Apollo Discovery Marine 58000-400MAR uses a single thermistor to sense the air temperature at the detector posistion. The thermistor is connected in a resistor network, which produces a voltage output that is dependent on temperature. The design of the resistor network, together with the processing algorith in the micro-controller, gives the 58000-400MAR an approximately linear characteristic from 10°C to 80°C.
The 58000-400MAR Discovery Marine Heat Detector is suitable for bases 45681-210MAR Discovery Marine Mounting Base and 45681-394MAR Discovery Marine Sounder Visual Indicator Base. For higher water ingress protection, the 45681-217APO Deckhead Mounting Box can be used.
