J.1.2 In circulation areas, no door to a habitable room should be further than 6m from the nearest smoke alarm, and no door to a bedroom should be further than 3m from the nearest smoke alarm.

J.1.3 The layout should ensure that the sound levels set pout in 10.3 are acheived.

J.1.4 Multi-sensor or optical smoke alarms should be used in living areas, circulation areas and escape routes. Heat alarms should be used in kitchen areas. Ionization or optical detectors should be used in bedrooms (all interlinked, mains powered and battery backed).
