Smoke Detector Testing Equipment

What is the Smoke Detector Testing Equipment？

ZONSKY Smoke Detector Testing Equipment is designed to evaluate the response and accuracy of smoke detectors under controlled conditions. This apparatus generates a specified concentration of smoke or aerosol particles to simulate fire scenarios, measuring detector sensitivity, response time, and alarm activation thresholds. It is an independent smoke alarm fire detection, a dot-type fireworks detector, and is suitable for various functional detection of alarm device installed in civil buildings (according to the principle of scattered or transmitted light (optical principle) and ionization ionization principle (ion smoke) work).

Compliance ； GB4715-2005 "Smoke detectors—Point-type detectors using scattered light, transmitted light or ionization":

Testing items:

1. Response threshold value tests

2. Function test

3. Battery failure alarm test

4. Polarity Reverse Test

5. Pass power test

6. Repeatability test;

7. Position test;

8. Consistency test;

9. Power parameter fluctuation test;

10. Airflow test;

11. Environmental light test;

12. High temperature test

Main technical characteristics:

1. Ring-shaped box: modular design, with sensor reserved holes, reserved production plug-in interfaces, and upgraded expansion space;

2.Control section: The development of LABVIEW software for the development of the US NI company's special precision instrument is developed. The interface is clear and simple, and can automatically identify the parameter of the alarm, ventilation, records, automatic angle rotation, wind speed switching, etc.;

3. Optical density meter: reflex, earthquake design, automatic correction of automatic zero, automatic correction of smoke and dust pollution measurement bias;

4. Test smoke: Use liquid paraffin gas solids. The particle size is evenly distributed, the smoke production is stable, and the particle size accounts for more than 90%of the number of smoke particles. Automatic smoke-rising, the host is closed to control the rate of smoke and automatically removes the remaining smoke in the pipeline;

5.Circular air, mixing smoke, heating plug-in: Six cyclic fans, the fan is controlled by PWM, two layers of smokes, thyristor control heating rods;

6. Electric hanging disc: Use servo motor control to automatically control the orientation corner of the smoke alarm to install the hanging plate, and set a rotary board;

7. Smoke-exhausting air replacement part: controlled by large flow fans, and the check valve is provided by the computer program to perform control;

8. Intake system: adopt a multi-layer filter to ensure the cleanliness of the inlet in the smoke box;
