The ship's sound and light alarm air breathing apparatus (A, B, C type) has added some new configurations to the original configuration of the old standard.It combines a pointer pressure gauge with an electronic sound and light alarm. When the pressure inside the gas cylinder drops to 5.5 ± 0.5 MPa, the alarm emits a continuous buzzing sound and red and white flashing signals. Compared with traditional pneumatic whistle sound alarms, electronic sound and light alarms have the functions of simultaneous alarm sound and light, and different pressure stage light prompts to ensure that respiratory equipment users or on-site supervisors can obtain residual air pressure information and alarm signals through multiple prompt methods, thereby effectively ensuring the breathing and safe evacuation of users.
