Good day! I tried to install an alarm system at home along with smoke detectors and water leak sensors in order to prevent a fire and then at home. It turned out that the ajax guard is very easy to install and works well with a smart home. It was very surprising to me to see for the first time how after the water leak sensor is triggered, the pipe is blocked. This is an amazing miracle of technology. However, I have a question. Is it possible to make the smoke detector not work on cigarette smoke?
