GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM DUCT SMOKE DETECTOR DSD SERIES RECTANGULAR SQUARE PRODUCT DESCRIPTION The DSD Series, 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of –20°C to 70°C (–4°F to 158°F), and a humidity range of 0 to 95% (non- condensing). A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance. The DSD housing provides ample wiring space, a ¾-inch conduit knockout, and built-in short circuit protection to prevent damage to sensitive components during installation. High contrast terminal designations make wiring easy. With its 2:1 sensor-to-power capability, the power board of the DSD may be used to monitor a second sensor, D4S, simultaneously (i.e., supply and return side). As many as 50 detectors can be interconnected. When one unit senses smoke, all interconnected detectors will switch their relays; only the detector sensing smoke will go into alarm, thus pinpointing the fire source. All detectors must be used with a metal sampling tube, DST series.
