Apollo Orbis A1S Heat Detector with Flashing LED ORB-HT-11167-APO

Apollo Orbis A1S Heat Detector with Flashing LED ORB-HT-11167-APO

Apollo Orbis A1S Heat Detector with Flashing LED ORB-HT-11167-APOThe Orbis Heat Detector monitors temperature by using a single thermistor which provides a voltage output proportional to the external air temperature.OperationOrbis heat detectors have an open-web casing which allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limitthe alarm levelhas been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors also have a fixed upper limit but they also measure the rate of increase in temperature. A fire might thus be detected at an earlier stage than with a static detector so that a rate-of-rise detector is to be preferred to a static heat detector unless sharp increases of heat are part of the normal environment in the area protected by the heat detector.
