Product Description
Background
Engine compartments of buses are more tendency to catch fire than other enclosures due to the following: short circuit, engine wear, hot surfaces, reduced durability of materials, use of plastics, encapsulation of the engine, oil, and debris. It is not surprising that more than 70% of all bus fires occur in the engine compartment. Since buses are used for every day transport of people, the fire protection of buses should be top priority of every bus operator or manufacturer.
1. Temperature Sensor Model/Solenoid Valve
2. Detection Tube Model/Pneumatic Valve
Product Activated Principle
1.Temperature Sensor Model/Solenoid Valve
Step1: There is 3 temperature sensor installed in the engine room, temperature sensor feedback the the temperature to the control panel. The control panel can indicate the temperature at anytime. The control panel was installed in the driver room, driver can see the temperature at anytime.
Step2: Once the Temperature of engine room increase to 100℃, the control panel will activate the fire alarm. Driver will stop and check the situation. If necessary, driver will push the manual button on the control panel to activate the system.
Step3: Once the temperature still increasing, and reach to 140℃, the temperature sensor feedback the signal to control panel, the control panel will activate the solenoid Valve, the solenoid Valve open and discharge agent to extinguish fire.
Drawing for reference
The temperature sensor send temperature signal to control panel, the control panel can indicate the temperature at anytime, once temperature reach 100 ℃, the fire alarm was activated. Once the temperature reach 140℃, control panel will send signal to electric valve to open it. Then the agent was discharged from dischange tube and nozzles. On the control panel, there is a manual button and test button, reset button, in Emergency pushing the manual button can activate the fire system too.

2. Detection Tube Model/Pneumatic Valve
Step1:
Detection Tube ruptures to hole when temperature reach 140℃, and release pressure through the hole.(Or pushing the manual button of detection tube,pressure releasing from themanual button.)
Detection Tube ruptures to hole when temperature reach 140℃, and release pressure through the hole.(Or pushing the manual button of detection tube,pressure releasing from themanual button.)
Step2:
The resulting drop in pressure causes the head valve to be activated. At the same time the fire arlar was activated.
Valve was opened and agent was discharged through the discharge tubing to the nozzles.

Valve was opened and agent was discharged through the discharge tubing to the nozzles.
Step3:
Agent covering the area and suppressing the fire quickly and thoroughly.
This system is totally automatic and is totally independent of electricity.

Drawing for reference
Inside the Pneumatic valve there is a piston, it divide the valve cavity to 2 parts. The upper cavity connect to detection tube, the lower cavity connect to bottle. The pressure of the 2 side of the piston is same. During the fire, Once the detection tube detected fire and ruptured one hole to release the pressure. Then the pressure of 2 side of the piston happen different, the piston was moved to up, and the outlet port of the valve was opened, and agent was discharged from the pipe and nozzles. At the same time, the pressure switch send final to fire alarm, the fire alarm was activated. On the control panel, there is a manual button and test button, reset button. In emergency Pushing the manual button can activate the fire system too.
