Smoke detector wireless or normal? Combine? Where?

Hello everyone,

our single-family house will be finished soon and I am currently thinking about where to install which smoke detectors. Since I want to install a wireless smoke detector in the basement in the technical room (with soundproof door), the question now arises where else a wireless smoke detector should be installed and where a normal one is sufficient. Our house is relatively small and has about 60 square meters of living space per level.

1st floor: bathroom, bedroom, dressing room, two children's rooms, small hallway
Ground floor: entrance area, open staircase leading to the upper floor and basement, small storage room, open kitchen, living and dining area
Basement: technical room (simple soundproof door), office, two storage rooms, small hallway

My idea was to install a wireless smoke detector in the technical room and in the hallways on the ground floor and upper floor. In the living room and all bedrooms, normal ones without a wireless module.

Does that make sense? Or what do you think? Since the wireless detectors are significantly more expensive...

Regards
Michael

I have it similarly: radio in the basement technical room, hallway on the ground floor and hallway on the top floor plus bedroom. Separate individual detectors in the children's room, living room, and kitchen. Bedroom for this reason so you definitely hear an alarm at night!

Would link everything by radio. There is also a version with a gateway so that it can be accessed via a mobile device or the alarm can be received even when on the go. If a bus system is available, it can also be linked with that.

I wouldn't do such a mix of those who communicate and others who don't.

If anything, everyone should respond when someone notices something.

A few years ago, I renewed ours. Since the previous ones communicated with each other via cable, similar ones were bought again. Cost: 17 euros each. The matching radio module was apparently, as it is currently, about 30 euros.

But since there were already cables to the individual detectors here, such a thing was naturally omitted. In addition, not only 2 wires but 4 wires run to the detectors. The others supply the detectors centrally with power. The power supply battery is arranged so that it is easy to access, which saves me from repeatedly climbing ladders.

Of course, there are also smoke detectors with 10-year batteries. I just wonder if they really last 10 years. If not, the smoke detector might have to be disposed of prematurely.

By the way, depending on the heating system, a CO detector is certainly not a bad idea either.

Would take a cheap, ordinary smoke detector, without radio, without Wi-Fi.

What would be the price difference? If I were to start with wireless once, I would probably stick with it.

We only have normal ones, in the hallways, living rooms, bedrooms. They have been working perfectly since 2017, as we only realized yesterday when dust from demolition work in the basement, despite all precautions, made its way up to the 1st floor. We have ones that sit on a magnetic plate, so you can remove the detector with one hand.

Our electrician didn’t install one in the kitchen back then; he said it would go off constantly there. Should you have one there as well? We also don’t have one in the bathroom for the same reason...
