A unique magnetic locking arrangement was installed on the commercial security grille on this project in order to comply with the BCA (Building Code of Australia). The magnetic lock is generally wired to the building's fire indicator panel and is designed to automatically unlock and releease in the event of fire. In effect this arrangement creates a keyless egress system for emergency exit. ATDC does have other alternative locking methods for complying with the BCA, the type used depending on the nature and suitability of the particular project at hand. For ATDC's locking compliance with the BCA refer to ATDC's website at www.trellisdoors.com.au.

ATDC's commercial security grilles are particularly appealing to Australian railway stations due to their heritage design and for this reason they are used quite frequently for securing railway stations across the country. Queensland Rail, WA Rail, Vic Rail, Metrail and Sydney's Light Rail and NSW State Rail are all frequent customers. The heritage design has its origin in the scissor doors that appeared in many elevators and lifts in years gone by. For further information on the widespread use of ATDC's commercial security grilles to railway stations see an article at www.trellisdoors.com.au.
