2.3.4. Restaurants
These areas must be considered as relatively critical zones
in a hotel, due to the variety of ignition sources such as
candles or cooking and frying at the table and the number
of guests in the room.
Depending on the room dimensions and the expected
deceptive phenomena smoke detectors or multi-sensor
fire detectors with the combination smoke/heat are
recommended for monitoring restaurant areas.
More detailed information regarding fire detection in
restaurants is given in the document
“fire detection in
restaurants”.
2.3.5. Stairways
Because elevators must not be used in case of fire,
staircases play an important role as the primary escape
routes in hotel buildings.
As a general rule, a single smoke detector should not
monitor more than three floors on a staircase and one
detector is required on the top floor ceiling. In addition a
number of manual call points must be placed throughout
the escape route.
More detailed information regarding fire detection in
staircases is given in the document
