SecuriStar MCD 573 X-S

  • Combined smoke and temperature detector compliant with EN 54-5/7 
  • Optimal sensitivity thanks to Cubus levelling 
  • High false-alarm security thanks to temperature-supported smoke alarm evaluation

The MCD 573X is a hybrid fire detector: The temperature-supported smoke sensor provides early detection of smouldering, glowing and open fires with smoke development. Smoke sensitivity adapts to the prevailing ambient temperatures in the area and automatically regulates itself (Cubus levelling). The temperature sensor also detects fire with no smoke development when fires break out rapidly with high temperatures. The smoke detection system offers 2 programmable pre-signal levels. The temperature detection can be set to class A1, A2 or B, each combinable with the index S or R. The smoke and temperature alarms are signalled and parameterised separately. Self-monitoring, two-stage contamination display, and auto drift compensation guarantee optimal operability. Besides the programmable control output, the detector has a warning signal when ambient temperatures become too high.
