Keep life safety systems running. Be the tech customers trust.

Fire Detection Unlimited, Inc. (FDU) designs, installs, and maintains advanced fire alarm and life safety systems for commercial and industrial buildings — and our service department is growing. We’re hiring an experienced Fire Alarm Service Technician who can walk into any building, find the problem, and fix it right the first time.

This is a hands-on, customer-facing role for a seasoned tech who can troubleshoot, repair, replace, and test fire alarm and life safety systems independently. If you take pride in clean diagnostics, accurate documentation, and leaving every system fully functional and code-compliant, we want to talk.

Our core values guide everything we do and everyone we hire: we are inspirational, disciplined, accountable, transparent, aligned, and results-oriented.
