What’s New Version 1.7
[NEW] Failed Test Button - will stop the test so we can just enter the values. Because sometimes the battery fails immediately, and then I have to sit through the five minute timer.
[CHG] Accelerated Test now has blanks for Batteries Rated Capacity in Volts and Battery App Hours(AH)
[CHG] Buttons to run the test do not show up unless you fill out the BRC and AH
[DEL] Reset Button for Test
Description
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.
