Patol Limited
1 INTRODUCTION
1.1 General
The Patol 5000 Series of equipment is specifically designed for the protection of
establishments and systems where a movement of materials with a potential fire hazard is
a routine occurrence.
The 5610 Detector employs enhanced Infra-red monitoring technology that enables the
detection of fire initiating materials, whilst they are being transported, and before they have
reached a flame condition.
The unit has ATEX rating
II 2 G D
and thus may be installed in hazardous areas.
The system has many applications within industries such as Power Generation, Coal
Mining, Process Plant & Road / Rail Terminals and has been specifically designed to both
meet the rigors of these environments and to provide the reliability required.
The equipment monitors for fire and fire potential of materials in transit. The system can
detect anomalies where combustion has not yet been reached, but where there is sufficient
energy for a fire initiation upon destination arrival.
A typical example is in the coal feed systems on power stations where coal on the ‘out field
stack’ may very well smoulder with little adverse effect for long periods of time. However, if
imported to the power station it may have devastating effects on conveyor systems, holding
hoppers, blending plants etc.
Detection of hazards at temperatures below flame point including both embers and
buried hot spots.
Air purged system for
Dusty
environments.
Two wire operation - Powered by direct connection to standard fire trigger circuits or
addressable loop interfaces - Signalling mode user configurable to simulate smoke &
heat detector protocols.
Volt free relay contact output operation selectable as standard.
Twin high integrity detection circuit channels for maximum reliability.
Unique reflective cone lensing system provides wide uniform coverage superior to
ember/spark detectors.
Coincidence -
Double Knock
- option for unit detector channels as standard.
Timed auto reset / coincidence analyser circuit.
Tuned response - solar blind.
High degree of ingress protection - IP66.
ATEX/IECEx approved
Specifically designed for high EMC compliance.
1.2 Principles
The principle of operation is that
temperature dependant black body
emissions occur for all materials.
These emissions range through the
infra red spectrum to visible light.
Both the wavelength and level of
peak energy emission are related to
temperature.
Type 5610 detectors are designed
to detect the changes in these
emissions that occur when a hot
body enters the field of view of the
detector.
By the use of both optical filtering and electronic analysis of the various parameters the
system is blind to visible light from the sun or local luminaires, whilst being able to detect
relatively low temperature material moving through the field of view.
