It can be tricky trying to figure out where to place smoke detectors in your home or office. There may be some areas that are too tight or cramped, and it can be difficult to find the space for them.

But what about when you have sprinkler heads in the area? Can you place a smoke detector near a sprinkler head?

The short answer is yes—but there are things you should consider before doing so.

Can You Place a Smoke Detector Next to a Sprinkler Head?

The biggest reason why you should not place a smoke detector next to a sprinkler head is because of the potential for water damage. If the smoke detector is too close, the water from the sprinkler head could cause it to malfunction or even get damaged beyond repair.

That’s why fire experts suggest spacing smoke detectors at least four inches apart from each other in a room with both smoke detectors and sprinklers.

Fortunately, there are many types of smoke detectors on the market today that come in all shapes and sizes, so even when space is tight, you should be able to find one that will fit without coming into contact with nearby pipes or fixtures.

In fact, some manufacturers offer special “low-profile” models specifically designed for tight spaces like these.

That being said, if you do want to install a smoke detector near a sprinkler head, make sure you follow all manufacturer’s specifications and approved techniques at all times.

This will ensure maximum safety while still giving your family or employees peace of mind that they’re being protected by both fire and water systems working together.


Placing a smoke detector near a sprinkler head can be done, as long as it’s spaced at least four inches apart—eight inches apart if possible—and follows the manufacturer’s specifications and approved techniques at all times.

Smoke detectors provide an extra layer of protection against fires and other disasters, so make sure your home or office is equipped with enough reliable units that meet local building codes!

With proper installation and maintenance, you can rest assured knowing that your loved ones (or employees) are being protected from any danger posed by fires or other disasters.
