Public Emergency Call Intercom Telephone for Subway, Railway, Toilets, etc -JWAT421
Emergency communication devices are installed in subway cars. In case of an emergency or if a passenger needs help, the emergency communication device can be activated immediately to contact the train driver. The driver will assess the situation based on the passenger's report and notify the relevant station staff to proceed to the appropriate location. Once the train stops, the staff will board the train to handle the situation or provide assistance.
1. Simple Operation. With a simple design, the buttons are eye - catching,easy to identify and operate. Passengers can directly initiate a call request to the driver's cab or the vehicle monitoring center,enabling instant communication with the driver or monitoring personnel.
2. Data Recording. The device will automatically record the conversation between passengers and the driver or monitoring personnel, serving as an important basis for subsequent incident investigations.
3. Quick Response. The alarm system is equipped with a priority handling rule.When it receives a passenger emergency alarm signal, it will automatically prioritize the processing of this signal over other routine information.
Passenger emergency alarms are emergency communication devices installed in train carriages (such as subways and trains) to allow passengers to directly contact the driver or ground control center for assistance in case of an emergency. They typically operate by pressing a button and then communicating with the driver via voice according to the instructions (such as when the indicator light next to the word "Talk" illuminates). The driver will respond via broadcast or video system.
