Fire alarm design recommendations

(18) The following fire alarm recommendations are applicable.
a) Fire System documentation, including any purchase specification, tender document, design proposal,submission to enforcing authorities or insurers for approval and the certificate issued by the Designers
, should clearly identify the fire alarm system Category as well as, where appropriate, the areas to be protected and any specific proposals for the type(s) of detector to be used.
b) Any specification or proposal for a Category L5 fire system should clearly identify the rooms or areas that are to be protected by automatic fire detection.

NOTE 1 There might also be benefit in giving a simple description of the objective of the protection proposed, particularly in
submissions to enforcing authorities.

NOTE 2 The standard of protection (extent of coverage) of a Category L5 fire system might be lower or higher than that afforded by
Category L2, L3 or L4 fire systems.
c) In Category L3 and L4 fire systems, smoke detectors, or a mixture fire detection.
should be provided in the following:
— all escape stairways;
— all corridors;
— any other areas that form part of the common escape routes.
NOTE 3 Main access and egress stairways normally form part of escape routes, and should be treated as escape stairways.
