The System Sensor DUCTSD Series duct smoke detectors with a cover integrated smoke test port and fl exible confi gurations provides effi cient installation and maintenance.  

The DUCTSD 4-wire photoelectric duct smoke detector features a pivoting housing that fi ts both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airfl ow speeds of 100 to 4,000 feet per minute, temperatures of "“4 °F to 158 °F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in sensor head offers simple installation and maintenance. The cover integrated smoke test port enables easy testing and maintenance.  

The 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 and a convenient wiring diagram label located on the inside of the power side housing cover make wiring easy. As many as 30 DUCTSD 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 fi re source.  

An easy-access Test/Reset button and smoke test port makes it possible to test the unit with the cover on. The power board has an LED that can be used to indicate the status of the connected sensors, and a quick reference imprinted on the cover explains the LED status indications (Standby, Maintenance, Trouble, and Alarm). The DUCTSD smoke detector can be customized to meet local codes and specifi cations without additional wiring. The DUCTSD product line is compatible with previous System Sensor models, including remote test accessories RTS151 and RTS151KEY.

WARNING: Duct smoke detectors are NOT a substitute for open area smoke detectors; NOT a substitute for early warning detection; NOT a replacement for a building"™s regular fi re detection system. Refer to NFPA 72 and 90A for additional information.
