Honeywell - Conventional Rate of Rise Heat Detector - 2020R


The 2020R Rate of Rise 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 2020R 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 both rate of rise and static elements and is suitable for all areas where the ambient conditions do not normally exhibit rapid changes in temperature. 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.

The 2020R Detector also 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. An optional remote LED annunciator may be used to repeat any alarm signal. A variety of detector bases can be used with the 2020R Detector, providing application flexibility and compatibility with a wide range of conventional fire alarm panels. Please note: the laser triggering tool does not negate the requirement to test the detector as specified in BS 5839 Pt 1:2013.
