Ionization detectors are also very sensitive , they work by generating current between two electrodes if the current is disturbed then the alarm becomes active. The best place for smoke detectors of this sort is definitely the ceiling. Here is a location guide for determining exactly where to install smoke detectors. The best location for a smoke detector is definitely going to be the ceiling , wall-mounted fire alarms can be used but they should be placed with caution as placing one is a dead air space can render it useless.
The main benefit of using a ceiling-mounted smoke detector is that it can be placed in a centralized position. In this way, it can detect smoke rising up from all corners of the room. So if you were wondering where the smoke alarm placement should be, wall or ceiling, you should definitely try to mount it to a ceiling, it is much better that way.
Be sure to centralize it and keep it away from any windows, also make sure that the fire alarm is less than 12 inches from the ceiling line. Smoke alarms placement in the hallway of your house is also recommended. Depending on the length of your hallway you may need to place additional smoke detectors along the length of the ceiling. The distance between two smoke detectors should be no more than 30 feet.
A typical smoke detector setup should be equidistant from all corners of the room by about 21 feet. So when installing a detector make sure that the distance between the detector and the corner of the room is about 21 feet or less. Each floor of your house or building should at least one smoke detector on each floor. Each floor should have one smoke detector. Also, if the floor has rooms in it then each room should have separate smoke detectors as we have mentioned previously.
This is the most important smoke alarm placement. One of the major causes of concern in placing smoke detectors in the kitchen, is the chance of a false alarm. It is quite possible that the smoke from your stove may cause the fire alarm to become active.
To avoid this false alarm you will have to place the alarm at least 10 horizontal feet away from the kitchen stove. Smoke can easily rise to the top. Also, avoid smoke alarms placement near a window or anything of this sort like an exhaust fan. Keeping a fire extinguisher in your kitchen is also great practice. The smoke detector placement code is actually dependent on the location of the building. Some areas have different regulations and policies for smoke detector placement than others. So be sure to check out your local placement code to find out exactly where to install smoke detectors in your building.
The NFPA does have some general guidelines on this so be sure to check that out too. A general rule of thumb is to check the working of your fire alarm once a month. You can do so by pressing the button on top of it. These locations may cause nuisance alarms or reduce the performance of your alarm.
