The audio speaker unit module is the basic part to build an outdoor station for an audio door entry system.
Modules are available with 0, 1, 2 and 4 buttons.
These modules are normally combined together with additional push button modules but in the version with 1 button, they can be used individually for systems where the number of users is equal to the number of buttons.
