AUST – Essential Property Services advises that the Building Code of Australia (BCA) in Clause C3.5 Doorways in fire walls requires a hold open fire doors to close automatically upon the activation of a smoke detector or other detector deemed suitable under AS 1670.1-2004 ‘Fire detection, warning, control and intercom systems – System design and commissioning – Fire’. Fire door inspections are to be performed under AS 1851-2005.
The following illustration from BCA Illustrated depicts the automatic closing operation of both fire doors separating fire compartments 1 and 2 must be initiated upon the activation of a smoke detector in either compartment or upon the activation of the sprinkler system in fire compartment 2.
