АFDES «BSU-02»

Automatic fire detection and extinguishing system АFDES for land transport

Structure of the system:

No.	Name	Use
1	Control system unit «BSU-02AM»	address automatic detection of emergency temperature rise of the environment in the protected compartments; address light and sound warning to the driver about an emergency increase in the temperature of the environment and faults of the AFDES elements; starting of fire extinguishing means in manual or automatic modes. Additional features: samotesting of AFDES elements working capacity; change the number of protected compartments from one to four; programmed time delay of automatic start of fire-extinguishing means; recording of occurring events in non-volatile memory; engine shutdown when the fire detector is activated; activation of the vehicle’s sound signal when the fire detector is activated; transmitting signals about the state of AFDES using GLONASS / GPS; transmission of signals about the state of AFDES using the «GAN-bus»; assorting AFDES on a system of many units (up to three).
2	Linear fire detector	Monitoring of the temperature of the environment in the protected compartment with the issuance of a signal about an emergency increase in temperature (the operating temperature is selected depending on the temperature in the protected compartment).
3	Extinguishing appliances extinguishing the fire by applying an electric pulse to the contacts of the electric activator. As extinguishing agents, it is possible to use a wide range of powder fire extinguishing modules «Buran», or generators of fire extinguishing aerosol «TOR», «Doping».

The system is designed for automatic detection of emergency overheating or fire of equipment in the protected compartments of the vehicle, alerting the driver of an emergency and addressing the extinguishing of the resulting fire.

The protected compartments are equipped with linear thermal detectors and automatic fire extinguishing means.

In the case of temperature increase in the protected compartments (real fire mode), the system issues an audible and warning light.

The driver of the vehicle takes measures to stop and evacuate passengers.

Fire extinguishing agents are started automatically, or manually by the driver by pressing the start button.

Advantages of AFDES in comparison with the previous versions:

• Self-diagnosis of the device with the issuance of light indication;
  
• Fault monitoring (break and short circuit) on the channels of fire detectors and fire fighting means with the issuance of address indication;
  
• Monitoring and signaling of temperature increase in the protected compartment with the issuance of an address light indication and a sound signal;
  
• Emergency start-up of extinguishing agents;
  
• Possibility of forced starting of all extinguishing means in case of a fault in the alarm system.
