Frequently Asked Questions

Questions We Hear Every Day

Q: What is the difference between the MicroComm DXI and the MicroComm DXL?

The DXI is our legacy intercom system, supported through our technical hub with full documentation, parts, and field support. The DXL is the current-generation system, featuring distributed IP architecture for greater flexibility in large or complex facilities. If you are specifying a new build or planning a full retrofit, the DXL is the right choice. If you are supporting or extending an existing DXI installation, we carry the parts and expertise to keep it running

Q: Does Harding Technologies install the systems it sells?

Harding provides design support, specifications, submittal packages, and technical guidance, but installation is performed by your appointed electrical contractor or integrator. Our team works closely with contractors throughout the project to ensure the system is configured and commissioned correctly. We support the installation without replacing the installer.

Q: Are Harding products TAA and NDAA compliant?

Yes. Our MicroComm DXL intercom system is designed with compliance requirements in mind, including TAA and NDAA. For specifiers working on federal or government-funded projects, we can provide the documentation needed to support your submittal. Contact our team for the current compliance certificate list.

Q: What kind of support does Harding provide after installation?

Our technical support team is available Monday through Friday, 7 a.m. to 5 p.m. Mountain Standard Time, with on-call coverage for weekends and statutory holidays. We provide phone and remote support, documentation, AutoCAD drawings, and parts availability. For legacy systems, we maintain technical archives and can support troubleshooting for systems installed decades ago.

Q: Can Harding systems be customised for our facility?

Customisation is available at the faceplate and station-type level to meet the aesthetic and functional requirements of your facility. The core electronics platform remains consistent, which is what gives our systems their reliability and long service life. Our team can advise on the right station configurations for your application during the specification phase.
