SERIES 5000
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 5410 Sensor 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 system has many applications within industries such as Power Generation, Coal Mining, Process
Plant, Road Transportation and Rail Networks 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 with air pressure monitoring.
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.
Patol remote controllers/interfaces available for two wire operation.
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 some 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.
Specifically designed for high EMC compliance - CE Marked.
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.
The 5410 Sensor 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.
