Have you test out the smoke detector to see if smoking set off the smoke detector? When you do that, come back and let me know.
LOL, I know a thing or two about smoke detectors, and yes, I have tested your theory. Years as a Firefighter and certified instructor help a little. When you know, you come back and tell me. Do some research first, start with the NFPA. You might even get some good info at UL. But trust me, smoking rooms have smoke detectors in them, the same as a non-smoking room. Any hotel in this country (USA) would be shut down if they are found to not have smoke detectors.
All hotel rooms require a smoke detector, as per National Electrical Code (USA) and the US Fire Marshals office. All detectors are checked periodically. B'sides people complain when the smoke detectors start beeping every 30-45 seconds when the battery is low.
Now at the hotel I worked at heres the differences between our smoking and non-smoking room.
* Non smoking rooms dont have ash trays and matches
* Non smoking rooms blankets are washed less often.
* Non smoking rooms were sprayed down less with that "hotel smell", unless if some moron smoked in the room anyway.
* Non smoking rooms didnt have that "smoker smell".
