The Aiphone IM Series IM-1 Security Window System Set provides VOX operated hands-free communication between a customer and an employee on opposite sides of bulletproof glass. This set includes IMU-100 Controller and Base Kit, IME-100 Gooseneck Microphone installed on the base unit, IAI-100 Driver Unit and Acoustic Tube Kit, IAX-100 Extension Tube, ISE-100 Motion Sensor, and PS-2420UL Power Supply. The system uses a speaker driver and acoustic tubing to provide communication without compromising the integrity of the glass. This security window intercom system provides a means of communication for two people conducting business on either side of a security window, such as at a bank, theater, or law enforcement facility.
The acoustic tube system combines an acoustic tube speaker with a noise canceling microphone ensuring clear sound quality with sufficient volume. The acoustic tube is long and thin, ensuring that the field of vision between the operator and the customer is not obstructed. The circuit of the noise canceling microphone is built in to the acoustic tube system, lessening the effects of ambient noise and making sure the operator accurately hears the customer. The customer's voice is concentrated ensuring that nothing is misheard, and the operator's voice is detected by the VOX circuit and transmitted automatically.
The operation unit is put in standby mode by turning off the TALK switch so that the sound is not transmitted when the operator leaves the booth or does not want voices from inside to be heard outside. A volume switch is provided that can be changed from low to high when there is an increase in ambient noise or if a customer is hard of hearing. There is an built-in paging function for calling customers in a waiting room. A paging speaker (available separately) is required for this paging feature to be functional.
