2. DP721i 700 Series Conventional Optical Smoke Detector

DP721i 700 Series Conventional Optical Smoke Detector

The 700 Series photoelectric detectors include a sensitivity test mode 
that may be activated by simply holding a magnet near the detector's 
test point. This initiates a self-diagnostic routine and provides visual 
indication if service is required. This test mode allows field sensitivity 
testing without the requirement for external meters or test gas.

 
  • Automatic self diagnostics with dynamic full detector and sensitivity test
  • High false alarm immunity with floating background with drift compensation
  • Separate fire and fault LEDs for unambiguous alarm reporting
  • Wide operating voltage for use on most conventional systems
  • Polarity insensitive for carefree installation
  • Manual self diagnostic with visual sensitivity indication
  • Field exchangeable and disposable optical chamber
