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.

Q: Smoke Alarm Production Test Tunnel

Device features: Production smoke boxes are developed from standard smoke boxes and are used for batch testing or calibration in the production of smoke alarms and detectors. The production of smoke box adopts the same smoke generator and smoke density meter as the standard smoke box, which is composed of the main body of the smoke box, smoke density meter and industrial control computer, in accordance with the standard specifications and parameters, with its own photoelectric sensor, which is used to detect the smoke concentration value in the smoke body, and adopts original imported components to ensure the accuracy and stability of the test. The smoke concentration in the smoke box is controlled by the intelligent PID control software, so that the smoke concentration dB/m value is kept within a constant range. Smoke alarms can be quickly placed in batches for batch detection, or sensitivity calibration. The specially developed Zontest Smoke Test Tunnel software continuously monitors the smoke concentration. The production of smoke boxes can also control the smoke rise rate, which can be used for sampling, R&D testing. Production cigarette boxes can be customized with different pallets or conveyor belts according to customer requirements. Equipment parameters: 1) Model: ZNEN14604-2 2) Power supply: 220V AC power: 5 kW 3) Standard: EN14604, EN54-7, GB20517, GB4715 4) Smoke generator: light paraffin water, particle size distribution between 0.5um~1.0um, 5) Optical smoke density meter: transmitted light, wavelength 880nm~950nm, range: 0~2 dB/m, 6) Box size: 2.2m x 0.5m x 1.1m. Flue cross-sectional size 430mm x 270mm 7) Wind speed: DC motor speed regulation, software set speed 8) Smoke rate: 0.005dB/m by default, which can be set in the software

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
