The Last Intercom System Your School Will Ever Need.

Most commercial intercom systems are designed to last 10 years. A school is designed to last 50. That gap is a problem for every facility manager, architect, and school district that has had to fund a system replacement mid-building-lifecycle. The MicroComm DXL was engineered differently. One system, built to serve a school from opening day through multiple generations of students, with parts availability and manufacturer-direct support to match.

Specify it for a new build. Retrofit it into an existing school. Either way, you are making a decision that your successors will thank you for.

Why the Lifespan Argument Changes Everything.

A 10-year intercom system in a 50-year building means five replacements. Five
procurement cycles. Five installation disruptions. Five rounds of retraining staff on a
new system. Five budget line items that could have been one.

The MicroComm DXL is designed around the opposite philosophy. Build it right the
first time. Support it for the full life of the building. Harding manufactures the
system, maintains the parts inventory, and provides direct technical support for
decades after installation. We still support systems that went in during the 1990s.
That is the standard we hold ourselves to.
