Family-owned · Dowagiac, Michigan

Keeping Southwest Michigan safe, secure, and connected — since 1980.

Commercial fire alarms, security systems, cabling, and access control — installed and maintained by a family-owned company that picks up the phone.

What we do

The systems that keep your building safe, connected, and code-compliant.

Haas Systems designs, installs, tests, and maintains the systems that keep commercial buildings safe, connected, and code-compliant. We work with business owners, facilities managers, and property managers across Southwest Michigan.

Why Haas

Local, code-compliant, and here for the long haul.

45 years
in business

Family-owned since 1980

Haas has been installing low-voltage systems in Southwest Michigan for 45 years. Two generations, one company.

Code compliance, not shortcuts

Every fire alarm install meets NFPA 72. Every cabling run is tested and documented. Do it once, do it right.

Responsive local support

We're in Dowagiac. When you call, we answer — and we can be on site, not on hold with a call center six states away.
