To help guarantee the performance of smoke detectors and reduce the number of false alarms from over-sensitive detectors, sensitivity should be measured in the field / on site. This statement applies equally to conventional and analogue systems.
Regular sensitivity testing is obligatory under certain codes and standards.
Trutest, introduces a smoke test aerosol to the detector while the detector is still connected to the alarm system, utilizing smoke obscuration sensing to measure and feedback information to a controlling microprocessor. It is the ultimate field tool and the only such device to provide a full, measured, 3rd party test using, measured simulated / surrogate smoke
Not only does Trutest represent the most complete and most sophisticated measurement (not just a test but a measurement) of sensitivity it also, by introducing a physical stimulus, complies with the requirements for functional testing. Two tests in one.
