A School Intercom System That Lasts as Long as the Building

Keep every student, teacher, and staff member protected with a communication system built to serve your school for decades, not years. Specify it once, and know it will be there, working, when it matters most.

The Last Intercom System Your School Will Ever Need.

Most communication 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, as a complete communication solution 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.

Everything a School Needs. Nothing It Does Not.

Built to Last

Engineered for 20+ years

Designed to outlast the system replacement cycles that drain district maintenance budgets.
Seamless Protection

Simple for Staff. Reliable Under Pressure.

Intuitive operation for daily communication, lockdown alerts, and emergency coordination.
Unified Infrastructure

Scalable Across a Whole District

One platform across multiple buildings. Consistent specification, consistent support, consistent cost.
Support That Lasts

Manufacturer-Direct Support for Life

Parts availability and live technical support from the manufacturer, not a third-party service desk.

Everything Your Specification Needs.

Harding provides everything needed to get the MicroComm DXL into a school project specification.

Why the Lifespan Argument Changes Everything.

Every school district has its own security protocols, lockdown procedures, and emergency response plans, and those needs shift over time. A 10-year system forces you to replace your communication infrastructure before your protocols even finish evolving. Five procurement cycles, five installation disruptions, and five rounds of retraining staff over the life of one building is a cost most districts can’t absorb.

The MicroComm DXL is built around a different philosophy: one solution designed to adjust to your security protocol, not the other way around. Harding manufactures the system, maintains the parts inventory, and provides direct technical support for decades after installation, so as your district’s procedures evolve, your communication infrastructure evolves with them. We still support systems installed in schools during the 1990s. That is the standard we hold ourselves to.
