OOHC740 ASA Detector

Email
Part no.:
For use requiring the highest level of immunity to deceptive phenomena.

Scope of delivery

  • Point Detector and dust cap

Application

  • For the early detection of soldering fires that generate CO
  • Areas with increased CO exposure, e.g. heating rooms, combustion plants, fermentation plants, garages, automotive workshops, animal stalls, chemical laboratories or production sites
  • For reliable fire detection on an environment with deceptive phenomena
  • Can be used on an addressable detector line, a collective line, or a conventional detector line


Function

  • Functions according to the scattered light principle with two sensors, optical forward and backwards scattering
  • Opto-electronic measuring chamber that obstructs disruptive extraneous light but provides excellent detection of both light and dark smoke particles
  • Two additional heat sensors and an additional CO sensor increase the point detector's response behaviour and immunity to deceptive phenomena
  • Built in Short Circuit isolator
  • Technical message, ambient supervision: Technical message if the temperature or CO concentration exceeds/falls below pre-set limits
  • Functions using an electro-chemical CO cell
  • CO concentration alarm is transmitted to an independent technical CO alarm channel
  • Independent processing of the CO signal for the CO alarm channel and CO signal for he fire detection
  • Selectable detection behaviour of the CO alarm channel, regardless of ASA parameter sets for fire detection
  • Selectable detection behaviour thanks to application-specific ASA parameter sets
