Question:
Is there any professional testing equipment for Smoke Detector being used in Manufacturing factory?

I found some testers like Trutest, Solo and Gemini 501 Smoke Detector tester on the web but they are only useful on field testing.

I am in search of some professional devices that is being installed and used in production line of some smoke detector manufacturers...

Answer: -Sentrol sells spray smoke. If I recall correctly some smokes spec not to use spray smoke to test.

-Many new smokes have a test button to simulate smoke conditions. Some have a reed switch mounted under the cover. Those you test with a magnet.
