Position smoke detectors optimally

Hello forum,

I need your collective knowledge. I know that every bedroom should have a smoke detector. However, I am unclear about how it works with an open-plan kitchen and where the smoke detector should ideally be positioned in the hallway. I would be grateful for practical tips.

In the hallway, I would install the smoke detector approximately where the wall between [Bad1] and [Bad2] is. So that smoke can quickly reach the smoke detector from both directions. In the living area, a smoke detector is not required. I would personally still install one. Even if someone sleeps on the sofa or falls asleep unintentionally, it can’t hurt to have one there. I would place the smoke detector in the center of the living area. It shouldn’t be too close to the kitchen.

Regarding the hallway: For L-shaped living areas, ideally place it centrally at the intersection, i.e., the leg. Otherwise, our chimney sweep recommended installing it as close to the doors as possible so that smoke from the neighboring room is detected quickly.

In every room (except kitchen and bathroom) as well as in the hallways, there is a smoke detector.

These communicate with each other via wired connection. This happened because in the past there were no units with wireless modules but wired ones. And when the old ones were replaced, there was no need to additionally purchase the rather expensive wireless modules.

The manual for the detectors also included corresponding instructions on where to install them. Things like 0.5 meters from walls and room corners. And other notes.

What do you mean by earlier? At the latest every 10 years, the detectors should be decommissioned and replaced anyway, and of course there were also wireless variants 10 years ago.

The old ones served a few years longer than they actually should have. They were still paid with DM and I also cannot remember that the dealer (was one who sold electronics alongside tools, garden items, etc.) already had anything with [Funk]. I mean no. But it doesn't matter whether there was something or not, the fact is that the old ones here were connected to each other by wire and the new ones are now as well.
