Equipment function: The aerosol generator atomizes liquid paraffin into aerosol through the nozzle. It is mainly designed for the sensitivity and function test of smoke alarm and detector. SM220 aerosol generator adopts compressed gas to atomize liquid paraffin, therefor the aerosol generator includes precision pressure regulating valve and pressure gauge and time controller. It combines two operation modes: external and internal control modes. In external control mode, the aerosol on/off is controlled by 20VDC input signal. In internal control mode, the aerosol on/off is controlled by embed timer and external 24VDC power supply. The work duration and time interval are settable on time controller. Equipment parameters: Model: SM220 Power supply: 24VDC 50W Air supply: 0.5Mpa, dry, oil free, Agent: liquid paraffin Bottle: 100ml

Q: CO alarm calibration chamber

Equipment Function ： The equipment is intended for gas alarm or Carbon monoxide alarm testing and calibration in mass production in advantage of its big volume. The equipment provides a sealed stainless-steel chamber with glass wall for monitoring alarm status. The special designed big open door can close and secure easily without gas leakage. The volume of chamber and size of samples shelves are custom-made. It can hold 100 alarms normally. The controller injects quantitative high concentration gas into chamber and the gas stirred by circulating fan to get homogeneous test gas in certain concentration. That gas will be test gas for response test or threshold setting of gas alarm product. The circulating fan and porous plate are also specially arranged to get uniform test gas and avoid the high concentrating gas getting into alarm directly during gas injection. On the top of chamber, the inlet and outlet and exhaust fan are controlled by PLC to exchange air in chamber. Component ： CH4/CO gas controller Set the gas volume and inject gas with precision control. The gas was injected in to chamber in short time and mix quickly. It is easy to count response time of alarm Control precision: +/-5ppm CH4/CO alarm test chamber. 1）Stainless steel chamber with glass windows. 2）samples shelves, can fit with customized adaptor to connect with alarm for power supply or signal transmission 3）Chamber size: 1.8*1.0*0.8m 3.Gas analyzer, CO or CH4 (customer provide or quote additionally)

Q: GAS alarm calibration chamber

Equipment Function ： The equipment is intended for gas alarm or Carbon monoxide alarm testing and calibration in mass production in advantage of its big volume. The equipment provides a sealed stainless-steel chamber with glass door for monitoring alarm status. The special designed big open door can close and secure easily without gas leakage. The volume of chamber and size of samples shelves are custom-made. It can contain about 60 alarms. The controller control high speed valve to inject quantitative high concentration gas into chamber and the gas stirred by circulating fan to get homogeneous test gas in certain concentration.

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.
