CM Expander Unit

Discontinued

Expands the CM-30 in increments of 30 lines

Each CMX-300 provides an additional 30 lines to the basic 30 lines provided by the CM-30. You may add up to two Model CMX-300s which will allow one Observer to monitor up to 90 lines. All the standard features of the CM-30 are maintained when using the CMX-300. Installation is easy (see User Guide).

You can add the CMX-300 to an existing CM-30 installation without disrupting the existing service. The CMX-300 is controlled by the CM-30: simply connect the additional lines you want to monitor and you’re ready to start.
No extra power supply unit is required. The CMX-300 gets its power from the CM-30.

Application

When your system needs to grow beyond the 30 line capacity of the CM-30, you can expand quickly and efficiently with the CMX-300. It will allow you to expand your system in increments of 30 lines per unit, up to a total of 90 lines.
If the size of your organization already exceeds 30 lines, the combination of the CM-30 and CMX-300 is your solution.
