MicroComm DXL was built for this environment. Not adapted for it. Designed from the ground up for the rigorous demands of corrections and high-security facilities across North America.
Correctional and high-security facilities put communication infrastructure through conditions that expose every weakness in a system not designed for the environment. Systems face constant high-frequency use, physical abuse of station hardware, and demanding integration requirements with PLCs, door control, and security management systems, all while having zero tolerance for communication failure during a critical incident.
MicroComm DXL digital intercom systems are built specifically to meet those demands. With proven performance across a large number of facilities throughout North America, MicroComm has become the system design professionals, system contractors, and facility owners return to, not because it’s the only option, but because it’s consistently the right one.
Trusted on 2,000+ projects across North America, and still going strong.
No matter how many simultaneous calls are active across the facility, no station is ever blocked. In a critical incident, that is not a feature. It is a requirement.
Clear, crisp, and intelligible communication under real-world conditions. Gain settings and audio filters are configurable on a per-station basis to compensate for varying room acoustics across different areas of the facility. Excellent speech quality reduces operator stress and minimises the risk of miscommunication.
Rugged construction and fault-tolerant design ensure system continuity in demanding conditions. Digital switching eliminates mechanical relays and their corresponding reliability issues. Line supervision to each station detects open and short circuits, and extensive diagnostics tools quickly identify problems to minimise maintenance time and cost.

Every station in the system has its own dedicated 1W audio amplifier. No matter how many simultaneous calls are active across the facility, no station is ever blocked. In a critical incident, that is not a feature. It is a requirement.

Conventional relay-switched intercom systems fail in high-use institutional environments because mechanical relays wear out. MicroComm DXL routes all audio in the digital domain, with no mechanical relays anywhere in the signal path. The result is a system that performs reliably under sustained high call volumes, year after year, regardless of facility size.
Up to 32 MicroComm DXL exchanges can be interconnected to form larger systems, handling the station counts of any correctional facility from a small detention centre to a major institutional campus. The same platform scales from the first station to the last without changing architecture.
Design professionals do not keep specifying MicroComm DXL out of habit. They specify it because it has a track record in correctional environments that alternatives cannot match. The Utah State Correctional Facility. The Edmonton Remand Centre. Washington State correctional facilities. These are not pilot projects. They are large-scale, long-term installations that have validated the platform’s performance under real institutional conditions over years.
Harding has been manufacturing intercom systems from Edmonton, Alberta since 1969. Every MicroComm DXL is built under ISO 9001 certified processes and backed by manufacturer-direct technical support that remains in place for the full service life of the system. We still support systems that were installed in the 1990s. When a design professional specifies MicroComm DXL, they are specifying a system with the manufacturer standing directly behind it, not a product that will be discontinued the moment the next generation arrives.
