Install them on a high wall or in the ceiling because smoke and fire rises. Having mentioned price, you might as well consider testing one of these so called smart smoke detectors. Some of these can be turned off by waving your arm at it in case it is accidentally set off. These smart detectors also give out a preliminary warning tone that tells you there’s smoke somewhere in the house, and gives you a chance to act. Other than that, smart detectors are also connected in a wireless network, and are able to talk to each other. So if a fire occurs in the basement and you’re in the bedroom, these smart little things will still sound the alarm wherever you are in the house. With a price tag of $149, the Halo Smart Protect is undeniably one of the most pricey options on the market. The manufacturers market the device as the “most comprehensive solution for any home”, which in turn means that the manufacturers believe that the hefty price is justifiable. As its name suggests, the Halo Smart Protect is a circular device that comes with a nifty user configurable light, which shines upwards towards the ceiling. Just like the colour turnable bulb, you can select the colour that you want from a colour wheel found on the device’s phone application.
