The smoke heat detector test tunnel was designed for sensitivity test of Smoke or Heat alarms/detectors according to GB 20517GB4715EN 14604EN 54-7EN54-5BS 5446-2 and ISO standards. It consist of insulated test tunnelaerosol 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.1ModelZNEN54-75HC 2Power supply380V AC 20 kW5m power cord provided 3Tunnel size: 3.1m x 0.7mx 2.1m. 4The tunnel section size is 450mm x 400mm 5Aerosol generatorBuilt in Thomas brushless pump imported from Germany, AgentLiquid paraffin, 500ml provided Particle size distribution between 0.5µm~1.0µm, Smoke rising rate: 0.015 dB/m/minm /t0.1dB/m/min, preset to 0.05dB/m, which can be set in the software 6Optical smoke densitometer: ADI circuit and advanced optical design transmitted light, wavelength 880nm~950nm, range: 0~2 dB/m, measuring range: 0 ~ 2 dB / m, measuring error shall not be greater than m×5%+0.02dB/m 7Wind speed: 0 to 1.5 m/s continuously adjustable via software setting when the wind speed is set at 0.2m/s, the fluctuation range is less than ± 0.02m/s; when the wind speed is set at 1m / s, the fluctuation range is less than ± 0.1m/s 8High temperature test function of smoke fire alarm: room temperature ~ 55 ° C, temperature control accuracy + / - 1 ° C, dry heat sensitivity test can be carried out in the smoke tunnel, standard number can be selected by software, and the program can automatically control to the corresponding temperature, which can meet the different requirements of European and China standards 9Low temperature test function of smoke fire alarm: 0 ° C ~ room temperature, temperature control accuracy + / - 2 ° C, and 0 ° C before sensitivity test can be conditioned in the smoke tunnel 10Dazzling tes .
