ABBM251021AA
The ABB Audio Module (No Pushbutton) provides two-way communication with indoor stations in your ABB Door Entry System. With a built-in speaker and microphone hidden behind a solid aluminum face (no speaker holes), the module installs in a custom outdoor station to provide the system's required audio component. Communication can be established either by the resident at an indoor station, or by the visitor at the outdoor station if the station provides a Pushbutton Module or Keypad Module (sold separately).
