If you have a building that is sprinklered, you may have heard a common response that smoke detectors are not required. Whoa, what was that? Smoke detection not required?
If that makes you concerned about your building being fully protected, it should. There are times when smoke detectors are required when the building is sprinklered.

Here are the most common 20 occasions where smoke detectors are required:
