About VoltVerify

Volt Verify is the go-to app for fire alarm technicians using the New Silent Accelerated Test method.

Time your test, enter the final voltage, and get an instant pass/fail result. The battery capacity calculator determines the required battery size and gives you an instant pass/fail result based on your system values — no notebook or calculator is needed. Easily save and share test results for quick documentation and reporting.

Built to support compliance with the new CAN/ULC-S536/S537-19 battery testing standards, Volt Verify helps technicians stay accurate, consistent, and code-compliant.

Fast, silent, and accurate battery testing, all in your pocket.
