Equipment Function ： The equipment is intended for smoke alarm or smoke detectors sampling test. The smoke box is constructed typical sensitivity smoke test chamber construction as specified in appendix B of UL 217 8 th editions or UL 268 similarly. 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 DC power supply Exhaust fan: AC fan Photocell: as standard recommended Lamp: as standard recommended Data acquisition device: Computer with National Instruments DAQ card Aerosol generator: special design aerosol generator that can adjust build up rate and particle size to meet the UL 217 and UL 268 test profile. 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 217 and UL 268 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.

Device features: The composition of paraffin oil for smoke generators mainly includes mineral oil, water and soluble powder. Among them, mineral oil is one of the main components of smoke generators, and its role is to provide volatile substances that enable oil to be converted into smoke. Water is added to reduce the risk of fire from the oil in the smoke generator, and its role is to improve the safety of the smoke generator. Soluble powders are used to increase the density and stability of smoke. The smoke produced by the smoke generator is safe and non-toxic and will not cause harm to the human body. The main components of the smoke sprayed by the fire smoke generator are water and propylene glycol, which is food-grade smoke, safe, non-toxic and residue-free. Equipment parameters: 1) Model: 500ml 2) Brand: Zhijian 3) Odor: colorless and odorless 4) Medium: light paraffin water

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: ZNOBS110 Obscuration meter

Equipment Function ： Optical smoke density meters are mainly used to measure the concentration of smoke or aerosols. The ZNOBS110 optical smoke density meter emits transmitted light from an infrared light source through the testing area of the smoke box and reflects it into the photoelectric element. By measuring the attenuation of the photoelectric signal, the concentration of smoke or aerosol in the smoke box is measured. The intelligent inspection instrument ZNOBS110 model optical smoke density meter adopts imported components and advanced photoelectric system, which can withstand the influence of environmental temperature changes and environmental light. Zero drift and temperature drift are extremely small, and can operate stably for a long time. The ZNOBS110 optical smoke density meter is suitable for use in standard smoke detector test boxes, fire test rooms, and other applicable occasions such as EN 54-7, EN 14604, GB 4715, GB 20517, etc. Specification ： 1) Model: ZNOBS110 2) Power: 12VDC Power: 10W 3) Applicable standards: EN14604, EN54-7, GB20517, GB4715 4) Detection type: Transmitted light 5) Light source wavelength: 880nm~950nm, 6) Range: 0-2 dB/m, 7) Zero drift 0.2% F.S.

Q: Imported standard cotton wick cotton rope smoke alarm test
