The Alkmaar Railway Signaling electronic bell type EBA
The ARS electronic bell type EBA replaces the electromechanical bell. The bell is used for railway crossings and in systems for closing off bridges. A special feature is that the sound pressure can be adjusted and that the bell has a day/night switch.
The casing of the bell is made of cast aluminium. This makes the bell suitable for all weather conditions, including tropical climates. The electronic bell type EBA can be assembled as a stand-alone construction unit.
The electronic bell type EBA is available in a large variety of voltages. That is why nearly all types of closing systems are equipped with a bell made by ARS.
