Independent – Code-Compliant – Trusted

ULC-S537 Fire Alarm Verification — ensure your system is installed correctly and functions exactly as designed.

Fire Alarm Verification

Every device. Every zone. Every signal. Verified.

Before a fire alarm system can be commissioned, ULC-S537 requires a formal third-party verification of all field devices, wiring, programming, and annunciation. Integra-Guard provides certified, unbiased fire alarm verification — with a focus on code adherence, clean documentation, and zero rework.

We handle both new installations and system modifications. Our detailed verification sheets and signal tracing ensure that your system is safe, functional, and ready for AHJ approval.
