The smoke alarm production test tunnel was designed for batch test or calibration of sensitivity test of Smoke alarms or detectors. The basic work principle is compliance to EN 14604 and EN 54-7.
It consist of test tunnel，aerosol generator, obscuration sensor, controller and computer. The obscuration meter was made of high quality electrical and optical components to ensure precision and stable reading. The two floor trays support by rodless air cylinders. They can extend and extract by press button or automatic control. The lids are fixed on tray and can close the opening in extended position and extraction position.
The Zomtest Smoke Test Tunnel Software in English is able to set the air speed, aerosol buildup rate (ramp test), constant OBS set value. The aerosol concentration is controlled to set value by PID algorithm and can maintain the smoke density with +/-0.004dB/m in reading.
