sec.12 Placement of smoke alarm

For each bedroom of a domestic dwelling a smoke alarm— must be installed— if it is practicable to mount the smoke alarm on a ceiling—on the ceiling; or if it is not practicable to mount the smoke alarm on a ceiling and an exposed joist or beam has a depth of no more than 300mm when measured from the ceiling—on the underside of the exposed joist or beam; or otherwise—on a wall in an area that is between 100mm and 300mm from the ceiling and more than 300mm from the corner of 2 walls; and if the smoke alarm is installed on a ceiling that slopes—must be installed in an area of the ceiling that is between 500mm and 1,500mm from the apex of the ceiling; and must not be installed— within 300mm of a light fitting; and if the smoke alarm is installed on a ceiling—within 300mm of a corner of the ceiling and a wall; and if the smoke alarm is installed in a stairwell—where smoke rising in the stairwell will not reach the smoke alarm because of an obstruction; and within 400mm of an opening from which air is supplied from an air conditioner or forced air ventilation; and within 400mm of the blades of a ceiling fan.
