MicroComm DXL digital intercom systems are specifically designed to meet the rigorous demands of correctional, industrial, and high security applications. Proven performance and reliability in a large number of facilities throughout North America makes MicroComm the number one choice of design professionals, system contractors, and facility owners.

MicroComm digital technology provides a high level of performance and a large feature set at a competitive price. A flexible, distributed architecture reduces wiring and minimizes the cost of installation. MicroComm systems are ideally suited for adding functionality and flexibility when retrofitting relay switched intercom systems.

Clear, crisp and intelligible communications are coupled with functions such as audio level alarm detection and discrete audio monitoring to provide a powerful communications system. A software-based configuration ensures that a MicroComm system is flexible enough to meet future operational needs.

Rugged construction, fault tolerant design, and comprehensive diagnostics make a MicroComm system easy to install and maintain. Modular construction simplifies the coordination of phased construction and facility renovations.

KEY Benefits

Clear, crisp audio is the hallmark of a MicroComm system. Excellent speech quality reduces operator stress and minimizes safety concerns. Individual level adjustments and digital filters help to balance a system and compensate for varying room acoustics.

MicroComm systems are reliable and require low maintenance. Digital switching eliminates the use of relays and their corresponding reliability issues. MicroComm systems are software configurable, making implementation of changes or additions straight foreword. Extensive diagnostics provide the tools to quickly identify a problem minimizing maintenance costs.

Audio and switch closure information is multiplexed onto single pair of wires reducing the number of cables and installation costs. The inter-exchange network allows the system to be distributed across several buildings. A fiber optic network provides protection from lightning.

Configuration software allows the system operation to be changed for different times of the week and different times of the day. Modular construction allows the system to easily expanded at a future date.
