MDS-CITY WITH CITYLINE PANELS

Introduction

Frequently some digital projects require several push-button panels due to the requirements of the customer. In these cases we can quote MDS-City system, which is completely available with CityClassic panels. However, these requirements are related to the use of our new Cityline panels and also, Skyline panels. Therefore, in this article we will explain how to connect the digitizer Ref.2440 to our 4+N Cityline and Skyline panels.

 

Arrangements

For this purpose, we need the following materials:

  • Outdoor panel: 4+N Cityline/Skyline amplifier and 4+N pushbuttons.
    • Remember that MDS amplifiers are 4+N (analogue).
  • Digitizer Ref.2440.
    • It is the responsible in MDS-City systems to digitize the analogue signals for our MDS system.
  • Call Extension Pack Ref.2441.
    • It is a needed device to connect pushbuttons in a digital system. Its purpose is to convert the received negatives from the pushbuttons to a valid digital address for the system.

 

How to connect

The following diagram indicates how to connect these devices to get a Cityline MDS-City panel. In this case we cannot use the cable from the connector CN1 to the digitizer directly, as we used to do in CityClassic panels, because the pins of these connectors do not match. Instead, we have to connect the wires to the corresponding outputs of the amplifier, as we can see on the picture and schematic:

 

 

How to install

Now, we know how to connect the digitizer, but we have another important question to solve and is: how to install this digitizer in the front panel.

Related to the measures of this digitizer, the best solution here is to order a Cityline special panel or using Skyline with a blank module to fit the digitizer without any problem. Ordering a special panel requires filling the following template, drawing the Cityline panel that we want:

With Skyline, we have to quote a Skyline panel with a Blank module Ref.7443 and fit the MDS-City digitizer as we can see on the next picture:

 

Conclusion

We can get a MDS-City panel easily with Cityline or Skyline design following these steps:

  • Make sure that the digitizer fits on the outdoor panel, using a Special Panel or Skyline blank module as an example.
  • Connect the wires to the amplifier outputs instead of CN1 as it is shown in the diagram included on this article.
