We’ve all heard of Native Americans who used smoke signals to send simple messages over long distances. But sometimes when we see smoke it’s sending a message that’s very alarming: there’s a fire nearby and our life is in danger.

  • Special chamber design has greatly decreased dust levels and improved detection accuracy.
  • Dual LEDs for 360-degree visibility.
  • Advanced technology enables this detector to increase its precision in fire detection, improve signals to avoid noise interference and thus reduce unwanted false alarm.
  • Low current consumption that allows more detectors to be used with each control panel.
  • Dual contacts on the base which enhance the connecting stability between sensor and base.
  • All bases are fitted with a shorting spring to permit maintenance without disconnecting when removing the detector head.
