Smoke Detector Tester | 2.5 oz | Steel Fire Equipment

This is one of the best and safest products to test smoke detectors Especially older ones that don't have test buttons. I have a significant collection of vintage 1970s smoke detectors that still function and this is how I set them off. This is a much better alternative to cigarette smoke.

Just finished 97 units worth of smoke detector testing. 3 detectors in each one. Works great.

I bought this to test the smoke detectors in my home. It works exactly as described. Hold the can about 2 ft away and spray it for about a second. The detector should go off in a few seconds. This is way easier than lighting a candle and blowing it out, staining the detector and the ceiling with smoke. Pushing the test button on a smoke detector only confirms that the speaker and battery are working. You need to use a product like this to verify that it will actually detect smoke. Buy this product. It might save your life.
