Limiting Repeated testing

When performing fire tests, it is common practice to repeatedly light a fire and check the response. However, repeatedly exposing the sensors to smoke in short time intervals will result in poor sensor performance. After being exposed to smoke, the sensors need considerable time to re-settle and restore their original fire detection sensitivity.

The minimum necessary time gap between tests is one hour, however, the original sensitivity will be restored only after ca. 3 hours.
