Built In Smoke Detectors

In any given home the smoke detectors are in a fixed location. Based on the home layout there are certain places in which a detector is going to be found (such as near the stove). Yet, in most cases, smoke detectors are dinky plastic things screwed to the ceiling. They seem to be built under the assumption that people are going to be wanting to move their smoke detectors around from place to place.

This is a problem. The most common reason smoke detectors fail is because their batteries are low. The reason they have batteries in the first place is because they are non permanent fixtures in the home.

There is an easy fix for this. Smoke detectors can be built into the ceiling of homes and apartments. They can draw power directly from the electrical grid. There would be no need to have batteries. There would never be a question of "is there a smoke detector there?"

The easiest thing would be to install them while the home is being constructed. However, if there were electrical lines in the ceiling installing it after the fact would be no harder than installing a ceiling fan (easier in fact). As far as costs go, such a device would not run much more expensive than a regular smoke detector. However, the companies who manufacture smoke detectors would likely want to jack up the price because they would not sell as many in the lifetime of a home.

Similar systems already exist in commercial establishments. There is no reason they should not exist in homes.  They could save lives.
