The highly reliable D-A-F has been thestandard for over 75 years. The D-A-F is used for signaling overheat or fireconditions. In most applications the D-A-F provides the initial heat sensingthat is used to activate suppression systems using clean agent CO2 inertgases wet or dry chemicals or water.D-A-F detectors are widely accepted because they aredesigned with rate compensation. This provides a unique advantage over bothfixed temperature and rate-of-rise types of detectors because the D-A-Fdetector accurately senses the surrounding air temperature regardless of thefire growth rate. At the pre-determined set point the system is activated.Fixed temperature detectors must be completely heated to alarm temperature andtherefore a lag in response time may occur with a fast rate fire. Rate-of-risedevices on the other hand are triggered by the rate of increase in ambienttemperature and are subject to false alarms caused by harmless transientthermal gradients such as the rush of warm air from process ovens. The key to the detectors sensitivity is in the design. Theouter shell is made of a rapidly expanding alloy which closely follows changesin surrounding air temperature. The inner struts are made of a slower expandingalloy. Designed to resist thermal energy absorption and sealed inside theshell the struts follow temperature changes more slowly. A slow rate fire willheat the shell and struts together. At the set point the detectorwill trigger actuating the alarm or releasing the extinguishant.A transient rush of warm air up to 40Fmin. mayexpand the shell while not triggering the detector. By ignoring transient warmair excursions the D-A-F detector virtually eliminates false alarms prevalentwith rate-of-rise devices. If a fast rate fire starts the shell will expandrapidly. The struts will close actuating the alarm andor releasing the agent.The faster the fire rate of growth the sooner the D-A-F detector will react.

Apollo Orbis A2S Heat Detector with Flashing LED ORB-HT-11014-APO

Apollo Orbis A2S Heat Detector with Flashing LED ORB-HT-11014-APO

Apollo Orbis A2S Heat Detector with Flashing LED ORB-HT-11014-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.
