FIRE DETECTION IN AN OCCUPIED COMPARTMENT

A fire detection system includes a heat detector configured to monitor a fire detection volume; a smoke detector configured to monitor the fire detection volume; and an occupancy sensor configured to detect the presence of at least one person within the fire detection volume. The fire detection system is configured to monitor for the presence of a fire within the fire detection volume using the heat detector and the smoke detector responsive to determining, using the occupancy sensor, that the fire detection volume is unoccupied. The fire detection system is configured to monitor for the presence of a fire within the fire detection volume using the heat detector and not using the smoke detector responsive to determining, using the occupancy sensor, that the fire detection volume is occupied.
