I was asking myself the same question not long ago. Luckily the National Fire Protection Association (NFPA) has a comprehensive guide on smoke detectors. They recommend that a smoke detector be placed inside every bedroom in the house and outside every sleeping area. There should also be a smoke detector at every house level, including the basement.

The goal is, of course, to maximize escape time by ensuring early detection. Whether the fire is caused by human error, electrical fault, or even criminal activity, having many alarms around the house ensures that your family will have plenty of time to get out of the house.

After you get the alarms, install them properly and maintain them following the manufacturer’s instructions on their manuals. You should also get the alarms tested at least once a month, which companies like PD Building Automation can help you with. Finally, while shopping for smoke detectors, you should also consider getting CO2 sensors, like stores that sell one will often sell the other, and they’re both essential for home safety.
