There is an increasing tendency for fire alarm systems to be configured for coincidence operation (double knock) where two detectors have to operate before the evacuation signal is actuated.
Should the fire detection system be categorised P1 or P2 there is no real problem as the system design is based on property protection, but should the requirement for the system be “Life Safety”(L system) one should think twice before applying this principle of operation.

SANS 10400, which is a legal standard states" Any owner of any building who fails to maintain any provisions made to satisfy the requirements of sub regulation (T)1(1) (e) shall be guilty of an offence". (T) 1(1) (e) states "adequate means of access and equipment for detecting, fighting and extinguishing such fire is provided".
In short, by law the building owner has to maintain his fire systems or be liable for prosecution.
