We have found that the Zenitel Vingtor-Stentofon Turbine TCIS-2 along with the ITSV-1 work well for extremely noisy truck scale applications, however with some modifications. The TCIS-2 is not always loud enough for the noisiest trucks. We found that we were getting returns because customers weren't happy with the volume, and if the volume was set at maximum, there was sometimes clipping of the conversation. We solved that problem by turning down the volume of the TCIS-2 and installing an amplified horn speaker three feet above the Zenitel TCIS intercom. That gives the volume needed without the clipping since you have greater separation between the microphone and speaker.

The second problem we had to solve is that the ITSV-1 is not very loud as it comes from the factory. In noisy scale houses the scale operators could not hear the drivers. By logging in to the ITSV-1 phone from a computer, we found settings that increase the volume of the phone. If the volume is increased all the way, this can lead to a hissing noise on the scale phone when there are no trucks on the scale, but that goes away when there is noise at the scale.

We program our kit to work right out of the box, however we provide instructions on how to fine tune the system to your application. 

The system is self-contained and we recommend not putting it on an existing network.

Here are the steps you will take when you receive the equipment:
  1. Plug the POE Ethernet switch into power (you provide the switch or purchase one from us). We recommend bench-testing everything with known working cables before the final install. Each phone comes with a 6 foot CAT-5 cable, but you will need to make one for the outdoor callbox.
  2. If you have multiple outdoor intercoms, plug in the one marked Edge Controller or Scale 1 first using a standard CAT-5 or 6 cable with RJ-45 connectors. This is the server that drives everything. Let it boot up for around 60 seconds until the light on the button is solid very dim yellow.
  3. Plug the phone(s) and any other outdoor intercom(s) into the POE switch. Do NOT use the power supplies that came with the phone(s). They get their power from the POE Switch.
  4. Wait for the phone and other devices to boot up (about 60 seconds).
  5. Press the button on the outside intercom and it should make a call to the phone(s).
  6. The phone(s) have MPK speed-dial buttons programmed to call other devices. You may have to switch screens to see them.
  7. If using an external amplified speaker, see the wiring connections photo below. The horn speaker MUST be mounted at least three feet above the stainless steel callbox or it will interfere with the full-duplex and noise cancelling circuitry.
  8. Also make sure all of the unused holes in the outdoor intercom housing are sealed with the included plugs. Otherwise water can get in as well as noise, which can affect the circuitry.
  9. See the instructions for fine tuning audio below if needed
