1. Application scope
The normal type fire with several stages such as temperature rising, initial cleavage, smoldering, flame and burning.
The beginning stage is temperature rising stage, generally longer, usually up to hours even hundreds of hours. To prevent fire, it is better to put out fire in the slow heating stage.
The normal and main fire protection products in the market such as straight line light beam sense smoke fire detector, sensitive type fire detector, air sampling fire detector. The three types fire detectors' working principle which is the fire can be detected. At this moment, the fire has caused immeasurable losses to the building and warehouse.
How to put out the fire at the early beginning stage? FD384 infrared thermal imaging fire detector can supply the solution.
Infrared thermal imaging early fire detector adopt the second generation of non refrigeration focal plane sensor . It combine the image signal processing and embedded industrial control technology to anticipate the internal temperature based on the measured surface temperature of the target object.
According to the surface temperature rise rate, the actual value of the surface temperature and the internal temperature anticipation value, comprehensive judge whether it is on fire trend. And send out abnormal or alarm signal.
Infrared thermal imaging detector has characteristics such as small size, easy installation, accurate temperature measurement, high integrated level, effective long distance, no affection by the field visibility, all-weather use characteristics.
Especially to the other fire sensors & detectors detect fire through the temperature, smoke, flame, etc. The infrared thermal imaging detector can give an alarm signal, effectively avoid last fire stage when the inspecting object internal heat aggregation and before smoldering, smoke, flame.
And this detector can output standard video image with the special industrial control computer. It can carry out many functions such as alarm, remote alarm, video transmission, image playback. It is especially suitable for petroleum, chemical industry, papermaking, large warehouses, grain depot, unattended station, tobacco industry, open type & large space, etc where the conventional detector can not be used. It is a new generation of integrated and efficient fire detecting and early warning and alarm equipment.
In the remote control room we can through the software set the infrared thermal imaging detector, each infrared detector can be set for eight alarm areas, each area can be individually set reminders temperature, pre-alarm temperature, alarm temperature and remind temperature rise, pre-alarm temperature rise, temperature rise alarm.
2. Good compatibility
With the signal connection point such as failure, early warning, alarming. It can be equipped with various fire alarm controller. Standard RS485 interface, convenient multi machine networking.
Using a variety of electromagnetic compatibility (EMC) and comprehensive consideration in the design, implementation and application, from the system structure, technical measures, software and hardware platform, technical service and maintain ability. Using a variety of technical scheme to improve the efficiency of response, reduce the failure rate to ensure the system in high stability.
4. High protection degree
IP67, Double protection cover, pass the phosphine gas corrosion test.
