4.6 AutroFlame Multispectrum Flame Detector X33/1 PL
4.6.1 Description
The AutroFlame Multispectrum Flame Detector X33/1 PL utilises
advanced signal processing algorithms, supported by an embedded
32-bit microprocessor, to provide continuous protection in the
presence of false alarm sources and environments with infrared
radiation present.
The detector has built-in PowerLoop technology which makes the
detector capable of being powered and communicating with AutroSafe
Integrated Fire and Gas panels (IFG) on the same pair of wire, saving
cable cost and weight. Each detector has a built-in short circuit
isolator, hence no detectors will be lost because of a single break or
short circuit in the PowerLoop lines.
All alarms and faults, like dirty optics and temperature out of range,
will be signalled via PowerLoop.
The PowerLoop is a two-wire power and signalling bus connected in
ring topology and is galvanically isolated from the rest of the system.
The detector does not require any local power supply.
The detector has a detection range to gasoline of over 60m, and a
solid cone of vision for methane.
For further information, refer to data sheet.
4.6.2 Applications
The detector is suitable for applications that are at the extremes, and
where background infrared radiation is a normal condition (Offshore
production platforms, Offshore production ships, Refineries,
Production facilities, Loading racks, Compressor stations, Turbine
enclosures).
