TSL-ESCHA’s PKW21 buzzers are used in rail vehicles. The products installed in the door area warn passengers of opening and closing doors by means of various beeps. Thanks to the similar construction of the Presskey push button, the PKW21 sounder fits well into the overall picture of the vehicle along with push buttons and signal lights.
Up to seven different tones and melodies can be parameterized according to customer specifications. Thus alerting passenger to any situation on the vehicle.
Equipped with an optional adaptive adjustment to the ambient sound level, TSL’s PKW21 acoustic warning sounder ensures that each passenger hears the beeps at an appropriate volume. This ensures that the beeps are heard just as well in an suburban train with celebrating soccer fans as during a quiet night ride in an Intercity train car.
Optical feedback can also be added with the SLR120 signal light. The illuminated ring matches the size of the buzzer and uses red/green LEDs to indicate the status of the door. This results in even better passenger warning. The signal light encloses TSL’s PKW21 buzzer and uses its mounting screws.
