The world’s most technologically advanced field service test instrument for sensitivity testing of smoke detectors.

Smoke detector sensitivity can and does drift.To help guarantee performance of smoke detectors and reduce the number of false alarms from over-sensitive detectors, sensitivity should be monitored.

Regular sensitivity testing is obligatory under certain codes and standards.To ensure the sensitivity test is correctly performed, the technician must introduce smoke to the sensor through the sensing chamber. Sensitivity tests carried out through other means – such as laser, panel testing and magnet testing – are a test of the electronics of the detector only.

Trutest is a fully portable device, enabling fire alarm technicians to measure the real sensitivity of smoke detectors quickly and easily in one test.
