2. DP721I 700 Series Conventional Optical Smoke Detector

DP721I 700 Series Conventional Optical Smoke Detector

The photoelectric sensing chamber unclips from the detector for easy
field cleaning and service. During regular maintenance the detector
cover can be removed, the optical chamber removed and replaced by
a low cost, new chamber. On power up the detector auto-calibrates
and returns to normal operating mode without any further intervention.

  • 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
