As required by AS1851 - 5 yearly test
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.
Sensitivity testing is required under AS1851 every 5 years for detection systems and every year for gas suppression systems.
Trutest circulates a dosed smoke test aerosol via the detector and measures the smoke obscuration returning to the controller to control the obscuration level.
This process verifies the exact obscuration alarming points of each detector.
It is the ultimate field tool and the only such device to provide a full, measured, 3rd party test using measured simulated/surrogate smoke.
