Siemens 500-085081 Ionization Smoke Detector DI-B3
The Siemens DI-B3 detector is a plug-in, ionization detector and is designed for two wire system operation. The DI-B3 is designed with a fixed sensitivity designed for their individual high air flow applications. The DI-B3 consist of self-compensating dual ionization chambers and a highly stable solid state amplifier-switching circuit. One chamber detects the presence of combustion products, the second chamber serves as a reference, to stabilize the detector’s sensitivity for changes in environmental conditions. As products of combustion enter the sampling chamber, the chamber current is reduced producing a voltage change. At the time the voltage range exceeds the pre-determined threshold, an alarm is signaled to the control unit. The detector locks in upon alarm and must be reset from the control panel.
The DI-B3 detector is specifically designed for use in air ducts with air velocities between 500-4000 FPM when used with Fire Safety Series 3 air duct housings.
