Vision 2020PT

The 2020PT Multi-functional Detector uses a state of the art optical chamber and heat element combined with sophisticated algorithms to provide quick and accurate detection of fires.

The combination of optical and heat detection provides a faster response to ‘real fire’ situations, while at the same time reducing the risk of unwanted environmentally generated alarms.

The 2020F 58ºC Fixed Temperature Heat Detector is
part of the Vision range of detectors. Vision is a range
of conventional detectors, which have been produced
using the latest in manufacturing technology and
supplied with an array of installer-friendly advanced
features, making them ideal for all your conventional fire
detection requirements.
The 2020F 58ºC Fixed Temperature Heat Detector
uses a state of the art heat element combined with an
application specific integrated circuit (ASIC) to provide
quick and accurate detection of fires. The detector
incorporates a static element and is suitable where
ambient conditions normally exhibit rapid changes in
temperature e.g. kitchens.
A hand held laser tool can also be used in conjunction
with the Vision range of detectors for triggering the Vision
detector. With a range of several metres, the hand held
unit provides an effortless way of remotely triggering the
Vision detector.
