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
