Are there any regulations saying what type of fire alarm must be installed in shops, hotels, etc.?
I ask because I have been to hotels that have signs such as "keep bathroom door closed when using shower to prevent activating fire alarm".
Is the steam from the shower triggering an ion/optical alarm because the alarm thinks it is smoke, or is the temperature of the steam activating a heat alarm?
Or perhaps it depends on the hotel which they have installed?
I have to stay at a Travellodge next week and was wondering if I could take a George Foreman grill to cook some breakfast or whether that might lead to the hotel being evacuated!
