SDi Fire

Smoke detector sensitivity testing using the XTR AXIS device during a professional fire alarm inspection

SMOKE DETECTOR SENSITIVITY TESTING​

Not all detectors are as sensitive as businesses need. Over time, smoke detector sensitivity can drift. They may grow more sensitive or less sensitive, but either way, this fluctuation in sensitivity can cause the alarm to be ineffectual. Using detector testers to check the sensitivity of fire alarms is not only required by law but will also give you greater control over the sensitivity of the fire alarms you’re inspecting. SDi fire offers one of the best detector sensitivity testers on the market with Trutest.

With XTR AXIS, technicians can complete accurate and reliable sensitivity tests in approximately 3 minutes!

XTR AXIS

Sensitivity testing, designed for the way technicians work.

XTR AXIS delivers sensitivity testing in approximately three minutes, helping technicians complete more testing in less time. Its lightweight, compact design and flexible test cup make it easier to test ceiling, wall-mounted, and angled detectors. Designed to meet the needs of today’s technicians, XTR AXIS works seamlessly with DT Connect to automatically capture and record test results, simplifying documentation and transforming sensitivity testing into a faster, smarter, and more connected inspection process.

  • Sensitivity testing in as little as 3 minutes – complete more testing in less time
  • Flexible test cup – easily test ceiling, wall-mounted, and angled detectors
  • Lightweight 4 lb design – reduce fatigue during extended testing
  • Clearing Mode – reduce re-alarms and keep inspections moving
  • Automatic test result capture – audit-ready documentation without manual entry
  • Smart Prime™ – verify readiness before every test
  • Intuitive touchscreen interface – simplify setup and operation

Trutest 801

Trutest combines functional and sensitivity testing in one convenient package by adding smoke aerosol to the detector’s sensing chamber. Some detector sensitivity testers need to test the detector multiple times to get a reading on whether the detector has drifted in sensitivity. This, in itself, does not give an accurate reading of how sensitive the detector truly is. These two-test detectors can only tell you how much the detector has drifted since the first test, but it will not tell you whether that means the sensitivity is wrong now or was wrong in the past. With only one test, Trutest lets users measure the sensitivity of smoke detectors quickly, accurately and efficiently.
