Conventional Vision 2020 PT Smoke/Thermal Detector

The 2020PT multi-criteria detector belongs to System Sensor’s Vision range. This range of conventional detectors have an array of installer-friendly features, making them ideal for small, straightforward fire detection systems.

The 2020PT multi-criteria detector uses a state-of-the-art optical chamber and a thermal element combined with sophisticated algorithms to provide quick and accurate detection of fires. The combination of photoelectric and thermal characteristics provides a faster response to ‘real fire’ situations, reducing the risk of unwanted environmentally generated alarms.

It has an integral LED, which illuminates to provide a local alarm signal. This latches on, and remains illuminated until the detector is reset by a momentary power interruption.


  • Low profile design
  • Low current draw
  • Automatic drift compensation to reduce false alarms
  • Improved chamber design to minimise the effect of dust contamination
  • Ionisation-like reaction time to flaming fires without the associated environmental concerns of using a radioactive source
  • Remote led option
  • EN54 part 5 and part 7 certified (CPD approved)
  • 14 – 28 VDC operating voltage rate
  • -30°C to +70°C operating temperature range
  • Standard and deep bases with or without Schottkey Diode (2020B, 2020BSD, 2020DB, 2020DBSD)
