Gas release sirens are used in firefighting combust control systems, and when the system releases a extinguisher to extinguish a fire, the gas release siren flashes, warning people not to enter the current fire zone for fear of danger. It is usually installed at the entrance to the protected area's passageway, and when the gas release alarm is connected to the DC 24V, it flashes red warnings such as 'Spray Do Not Enter.'
