Apollo Orbis I.S. A1R Heat Detector with Flashing LED ORB-HT-51146-APO

Apollo Orbis I.S. A1R Heat Detector with Flashing LED ORB-HT-51146-APOThe Orbis IS Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. The Orbis IS range incorporates seven heat detector classes to suit a wide range of operating conditions.OperationOrbis I.S. 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 temperature and compares them with per-set values to determine whether a fixed upper limit - the alarm limit - has 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 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 then 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.Key FeaturesCan be used for applications where smoke detectors are unsuitableIdeal for environments that are dirty or smoky under normal conditionsReduced incidences of false alarmsIncreased reliability of detection
