SM-501-P

The Air Products & Controls SM-501 Series Duct Smoke Detectors provide early detection of smoke and combustion products present in air moving through HVAC ducts. Air sampling is accomplished by intake sampling tubes, which are ordered separately. A standard length exhaust tube is provided with each detector. The SM-501 Series is designed to operate in duct widths from 6" (15 cm) to 10.0' (3.05m) with an air velocity from 500-4000 fpm (2.5-20.3 mps). Complete systems may be shut down in the event of smoke detection.
