SP 484.1311500.2020, which came into force in 2021. “Code of rules. Fire protection systems. Fire alarm systems and automation of fire protection systems. Norms and design rules” introduced the concept of a fire detector with a video detection channel.Â
According to the definition, this is an automatic fire detector that performs the function of detecting a fire by analyzing a video image in the controlled field of view. Thus, it is now possible to use the video stream coming from existing cameras to recognize a fire. This is a serious step towards the digitalization of flame and smoke detection technologies (definitions according to ST SEV 383-87).
After all, neural network technologies can detect a fire several times faster than all the methods of its detection specified in previous regulatory documents. Amendment 3 to GOST R 53325-2012, which came into force almost simultaneously with the approval of SP 484.1311500.2020, defined the requirements and testing methods for fire alarms with a video detection channel. The ready regulatory framework became the impetus for the creation of such an alarm.
Considering that the fire detection tool in a fire alarm with a video detection channel is not the video camera itself, but a neural network detector, an analysis of the concepts set out in regulatory documents and regulatory legal acts was conducted. It was found that the definition of “Neural network fire alarm” is missing in regulatory documents, so the employees of the National Security Laboratories State Corporation decided to give the following definition: Neural network fire alarm (hereinafter ENSPI) is software that, based on the analysis of the image coming from the video camera, ensures the recording of the ignition of a test fire source by using artificial intelligence. The definition is based on the conceptual apparatus set out in the following documents: GOST R 51904, No. 123-FZ, GOST R 53325, GOST R 59276.
Domestic production.
Detection of a test fire source no later than the response time in accordance with GOST R 53325-2012 (Amendment 3).
The ability to customize the response to fire detection: issuing a signal to turn on the sound and light alert for the duty personnel; sending a message to e-mail; control of dry relay contacts; pop-up notification on the duty personnel monitor screen.
Highlighting the fire area on the software screen with a flashing rectangle.
Identification of smoke, flame combustion; issuance of a signal on detection of smoke; issuance of a signal on detection of flame.
The ability to configure the following algorithms for triggering fire alarms and turning on actuators: detection of smoke only; detection of flame only; detection of smoke and flame.
Registration of fire recordings in the event log for subsequent quick search in the video archive.
Display in the software interface on the video camera placement plan of the video camera that recorded the fire.
