The IM Series is a security window system that provides VOX operated hands-free communication between a customer and an employee on opposite sides of bullet proof glass. The system uses a speaker driver and acoustic tubing to provide communication without compromising the integrity of the glass.


  • Adjustable, flexible gooseneck microphone
  • Headset can be used (not supplied by Aiphone)
  • Uses voice-actuated (VOX) communication system, requiring no additional operations during conversation
  • When the TALK switch is off, the Operation Unit is put in standby, but sound from public side is still heard at reduced volume
  • By linking the system to a motion sensor, communication mode is activated when a customer is present
