Overview:
The HAQT-1 explosion-proof emergency start/stop button (referred to as the button) is a non coding button suitable for installation in explosive gas environments containing Class IIC T6 temperature group. This button is equipped with an anti misoperation cover plate. When a fire occurs in the protected area, lift the anti misoperation cover plate and press the emergency start button (white) to send a signal to the gas fire extinguishing control panel. The gas fire extinguishing control panel sends a gas spraying command, and after a delay, the gas spraying solenoid valve is activated.
