UTC Fire and Security SM200 Smoke-In-A-Can. Canned Smoke

Worked to test fire/smoke alarms. Contents quantity was overstated in the ad.

Smoke alarms should do more than just start beeping at 3am when you're in dreamsville. They should detect smoke! Unfortunately, the little green light on the alarm doesn't tell you that, so you need this product. It works! Now at least I know that my smoke alarms actually detect smoke, just in case there is a fire! I tested this on our ten-year-old, smoke-only alarms, as well as on our new smoke and smoke & CO alarms. They all sounded off. One can of this product tests at least four alarms, probably more since the can is not empty yet. Easy to use, I will never be without it! Also, do yourself another favor, and replace your 9v smoke alarm alkaline batteries with 9v lithium batteries. They should last about five to ten times longer, so you have to change them much less often.

This product has exceeded the performance that we were looking for. Needed a product that was reliable and surpassed standard testing.

I used it for checking my smoke detectors. It works well, but it is twice as costly as the others. According to the advertisement, I was supposed to get 2 cans for about $19, but I only received one. The company did reimburse me right away, though, for the 2nd can I didn't receive.

Testing smoke alarms. Point a shoot!

Used this spray to test smoke alarms, I was expecting some kind of smoke not a spray. We just put new flooring in and had to cover it because I didn’t know if the over spray would stain or not.

It works perfectly. Just testing the button on a smoke detector doesn't prove it would work in an actually situation. This proves it. No visible particles so a small smoldering fire would probably set it off. I'm very pleased. Thanks to my monitoring company for suggesting it. Now, I'm telling everyone.

Great way to safely test your fire alarms. The only problem is that the alarm will sometimes take a while (a minute or two) to go off because it takes a bit for the stuff to clear from the air.
