Duct Detection

Duct detectors are designed for detecting smoke in the air moving through heating and ventilation (HVAC) ducts in commercial and industrial applications.

They comprise a purpose-built housing complete with integral tubing, which samples the fast-moving air so that the detector can operate in the normal way.

Conventional Duct Smoke Detector

The Conventional Duct Smoke Detector provides early detection of smoke in the air moving through heating and ventilation (HVAC) ducts in commercial and industrial premises. Its purpose is to prevent the re-circulation of smoke from an area on fire to areas unaffected by the fire when used with a Series 65 or Orbis detector. It provides a volt-free changeover relay rated at 30V, 1A.

  • For use with Series 65 or Orbis detectors
  • Operates in air speeds of 0.5m/s to 20m/s
  • Transparent cover to view detector head LED
  • Integral smoke test port
  • Volt-free contacts

Intelligent Duct Smoke Detector

The Intelligent Duct Smoke Detector provides early detection of smoke in the air moving through heating and ventilation (HVAC) ducts in commercial and industrial premises. Its purpose is to prevent the re-circulation of smoke from an area on fire to areas unaffected by the fire when used with a XP95 or Discovery detector.

  • Operates in air speeds of 0.5m/s to 20m/s
  • Transparent cover to view detector head LED
  • Integral smoke test port

Extension Tubes

The duct smoke detector is designed to operate in ducts with a width of between 300mm and 3000mm. A sampling tube of 360mm, suitable for duct widths up to 540mm, is supplied as standard.

Longer sampling tubes may be ordered separately.
