Equipment
Function：
The
smoke heat detector test tunnel was designed for sensitivity test of Smoke or Heat
alarms/detectors according to GB 20517、GB4715、GB4716、EN 14604、EN 54-7 、EN54-5、BS
5446-2 and ISO standards. It consist of insulated test tunnel，aerosol
generator, obscuration sensor, heat element, cooler, controller and computer.
The obscuration meter was made of high quality imported part to ensure
precision and stable reading. The Zontest Smoke Test Tunnel Software in English
was designed by our software expert specifically to meet the standards test
requirements.
