INDUSTRIAL FIRE DETECTION
Industrial installations are ideal for SigniFire’s industrial fire detection solutions. Fire can spread quickly due to the presence of many flammable elements. SigniFire has already proven its worth; it has already been involved in protecting expensive machinery that are essential to the operation of the company. The industrial fire detection system is designed to protect installations that cannot be secured by conventional detectors.
Difficult environment
Industrial installations are generally large structures where automated machinery is used. The initial fires are usually caused by machines overheating. These fires can take hours to reach a size sufficient to be detected by conventional detectors. SigniFire cameras, on the other hand, enable the early detection of fires for industrial fire detection.
Why video detection of flame and smoke?
Video detection of flame and smoke has several advantages over traditional detection:
- Early detection:The cameras see the fire at its source and therefore manage to detect it. Earlier than conventional detectors. These require that the smoke reach their sensors.
- Immediate information on the situation: It is a network camera; the images can be viewed in real time in a remote monitoring center. Alarm verification is immediate and reliable.
- Less equipment to install: Each SigniFire camera covers a large area, which translates into a savings in sensors. The goal is one reduction of installation and maintenance costs.
How does SigniFire work?
The video analysis software uses artificial intelligence:
- Analysis of images of 640x480 pixels at a rate of 15 images per second.
- 4.5 million data points analyzed by the camera's Texas Instruments DSP processor.
- The software uses temporal patterns and DSP filters and compares the results with a neural network based on 15,000 fire simulation models.
- The alarms are routed via dry contacts and/or via Ethernet.
What industrial fire detection systems have traditionally been used in the fire protection of industrial facilities?
- Sprinklers: Sprinklers are triggered by an increase in temperature. They are designed to save the building’s foundations and not its contents.
- Linear heat detector:Linear heat detectors can be used upstream of the sprinklers. They are triggered at an increase in temperature, not at an early stage.
- BEAM detector: The beams are placed at the ceiling level and can causing false positives. These
are caused by an obstruction of the beam (objects, thick dust...).
- “Spot” detector: They are generally placed high up to capture ionization, which delays the detection of smoke.
- Suction system (ASD): ASD systems have one major disadvantage in dusty environments. The sensors are clogged, which impairs detection and increases the number of maintenance operations.
