Duct Smoke Detector-Superduct, Addressable (GSA-SD)

The SuperDuct Signature Series addressable duct smoke detector is the most advanced and most reliable smoke detector in its class.  Designed for easy installation and superb reliability, SuperDuct represents the perfect balance of practical design and advanced technology.

SuperDuct detectors feature a unique design that speeds installation and simplifies maintenance. Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. When cleaning is required, the assemblies come apart easily and snap back together in seconds.

A Signature Series photoelectric sensor is incorporated into the design of each GSA-SD duct smoke detector. This sensor inherits the power and benefits of this exceptional line of intelligent devices.

Signature Series sensors gather analog information from their smoke sensing elements and convert it into digital signals. The sensor measures and analyses these signals and compares the information to historical readings and time patterns to make an alarm decision. Digital filters remove signal patterns that are not typical of fires, which virtually eliminates unwanted alarms.

Standard Features

  • Less than 2" deep for easy installation and applications where space is tight
  • -4°F to 158°F (-20°C to 70°C) operating range with 100 ft/min. to 4,000 ft/min air velocity rating assures reliability under harsh environmental conditions
  • Status LEDs remain visible through clear assembly cover
  • Cover monitor switch for added security
  • Standard sampling tube spacing for easy drop-in migration from other detectors
  • Sampling tube can be installed with or without the cover in place and can be rotated in 45-degree increments to ensure proper alignment with duct airflow
  • 15.2 to 19.95 Vdc operation
  • Magnet-activated test switch
  • One individually programmable Form C auxiliary alarm relay for controlling ancillary equipment (e.g., HVAC controls) rated at 2A, 30Vdc (resistive)
  • No special tools required for easy access to field connections
  • Signature Series intelligence
  • Environmental compensation with differential sensing for reliable, stable, and drift-free sensitivity
  • Wide 0.79% to 2.46% obscuration/ft. smoke sensitivity
  • Identification of dirty or defective detectors
  • Measures 8"W x 5-1/2"H x 2"D
  • Agency Listings: UL, ULC, FM, CSFM, MEA

Note: The onboard relay follows the unit alarm.

Note: Removal of housing front cover reports a trouble to the fire alarm control panel in 20 minutes (Not user programmable.  It’s a feature and not required by any code or UL standard).

Note: Unit comes with mounting template, sealing gaskets for sampling tube and exhaust tube duct work entry points, sampling tube plug, two 1" #10 sheet metal self-tapping screws, exhaust tube, and test magnet.

Note: Order the sampling tube separately.
