Q: Smoke Alarm Production Test Tunnel

Equipment Function ： 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 when door keep closing. After exchange of samples tray, the smoke density will drop and then resume to +/-0.005 range within half minute. Specification ： Model：ZNEN14604-18 Power：220V AC 1KW Standards：EN14604,EN54-7, GB20517, GB4715 Aerosol generator：Liquid paraffin , particle size distribution between 0.5µm~1.0µm， Optical smoke densitometer: transmitted light, wavelength 880nm~950nm, range: 0~2 dB/m, Test tunnel size: 3.1m x 0.5mx 1.1m. Test section size is 430mm x 270mm Wind speed: DC motor speed regulation, software setting speed, from 0 – 1.2 m/s Smoke rising rate: preset 0.005dB/m, can be set in the software. Send Obscuration value to com port via Modbus RTU. client can read the value via RS 485

Q: UL217/268 Smoke alarm test system

Equipment Function ： The equipment is intended for smoke alarm or smoke detector sampling test. The smoke box is constructed typical sensitivity smoke test chamber construction as specified in appendix B of UL 217 8 th edition. It consists of the following items: Outer Cabinet: constructed of exterior grade plywood according to standards dimension Inner compartment: constructed of plywood according to standards dimension Circulating fan: DC fan powered Keysight DC power supply Exhaust fan: AC fan Photocell: Model 594 RR as standard recommended Lamp: Type 4515 as standard recommended Data acquisition device: Computer with National instruments DAQ card Software: Zon-test Smoke box software. The smoke box can be used to perform initial sensitivity test, directionality test, velocity- sensitivity test and other stability test with auxiliary equipment. Note: The UL standard required Measuring Ionization Chamber (MIC) to be included to monitoring smoke particles size. The MIC is not included in quotation if no specified but the mounting port and data acquisition connection port are reserved.

Q: Smoke Alarm Production Test Tunnel

Equipment Function ： The smoke alarm production test tunnel is used for batch test or calibration smoke alarm and detector in production process. The main parts, aerosol generator and obscuration meter are fully same as standards smoke tunnel to ensure high reliable test result. The aerosol concentration in the smoke box is controlled by fine-tuned PID to maintain constant OBS of smoke in a narrow range of +/-0.004dB/m. The smoke alarm production test tunnel is installed on production assembly line. The alarms are placed on the conveyor belt and flow into the smoke box. After passing through the smoke box, check the status of the alarm. You can batch quickly test the smoke alarm or calibrate the sensitivity. The specially developed zomtest smoke test tunnel software carries out constant smoke control and continuous monitoring of smoke concentration. The speed of the conveyor belt shall be adjusted according to the response time of the sensor to improve the production efficiency. Specification ： Model：ZNAL-7 Power：220V AC 1kW Aerosol generator：Liquid paraffin , particle size distribution between 0.5µm~1.0µm， Optical smoke densitometer: transmitted light, wavelength 880nm~950nm, range: 0~2 dB/m, Tunnel size: L1.4m x W0.49m x H0.7m. Customized width according to customer’s conveyor belt Wind speed: 0.2 to 0.8 m/s Smoke range:0.05 to 0.8 dB/m, set value±0.004dB/m

Q: Smoke Alarm Test Tunnel

Equipment Function ： The smoke alarm test tunnel was designed for sensitivity test of Smoke alarm or Heat detector according to GB 20517、GB4715、EN 14604、EN 54-7 、EN54-7 and ISO standards. It consist of 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.
