Siemens FDBH291 Detector Heating Element (Micro-Terminal)

FDBH291 is a heating element attached to the Siemens detector socket; by keeping the detector approximately 2 °C above the ambient temperature of its environment, it prevents condensation and frost formation in the sensor chamber. It draws 35…55 mA at DC 20…30 V supply and operates in the range of -30…+40 °C, covering cold and humid volumes such as unheated storage, attic spaces, loading ramps, or food storage. It seats in the socket with a spring clip in a single motion, requiring neither a separate connection fixture nor hole drilling. Order number A5Q00004439; the package includes 2 pieces of DBZ1190-AA micro-terminals. When used together with a FDB293 humid volume extension base at points of heavy moisture, it delivers the most efficient result.
