I'm not sure I understand the above statement.

The OP is - as far as I understand it - intending to place a mobile smoke detector in a hotel bedroom. My comments relate to the rationale for why Hotel bedrooms in the UK have smoke detectors in the first place
An old version of BS5839 allowed for detection in corridors only as a means for raising the alarm (for life safety purposes), including hotels .
However it was found that by the time the SD in the corridor activated, the corridor was often impassable due to smoke
A revised version of BS 5839 introduced a (category L3) detection system that had detection in the corridor and also the rooms leading onto the corridor. the rationale was and is, that the system will pick up a fire in the room & raise the alarm before smoke gets into the corridor & blocks the escape route.
Obviously, this includes hotel corridors and hotel bedrooms
Therefore, the smoke (or heat) detection in hotel bedrooms is part of a strategy to keep the means of escape corridor free and available, and is not there to protect the occupants of the room
This is why heat detection is allowed in bedrooms. heat detectors reduce unwanted fire alarm actuation, but their slow activation rate (compared to smoke detection) in effect, sacrifices those in the room, but will sound the alarm to save others.
Its hard to believe, but true
So taking a portable smoke detector does little to protect the occupant, as the most likely fire will originate away from the bedroom.
