Our house is fairly new (2013 build year). We moved in 2016. On the second floor we have 3 wireless smoke detectors and 1 wired and on the first floor we have 1 wired smoke detector and 2 wireless. They are all positioned in about the same area. I am curious why do we have so many and can we get rid off wireless (it is time to replace them anyway)
I am trying to research everything. And so far I only found something about ADT alarm. We do have ADT installed.
Update on position. On the second floor all smoke detectors are located in the hallway (not in bedrooms). They all positioned on the area of roughly 1 m^2. On the first floor all smoke detectors are in the hallway next to bathroom, laundry room, living room, bedroom and fairly far from kitchen. They are all positioned on the area of roughly 1 m^2.
More update I just carefully inspected the second floor and found out that there is smoke detector in each bedroom (total of 3), they are all wired. There is also extra wired smoke detector in hall way next to two bedrooms. Also one bedroom on the first floor has wired smoke detector. It seems like all other wireless smoke detectors are excessive.
