Detection systems, especially smoke detection systems, require significant
maintenance. It is critical that the required detectors are properly installed and
maintained. Providing detectors in locations that are not required increases the
already high maintenance costs of alarm systems and strains the maintenance
program for critical detection systems. If a facility warrants protection and criteria
does not require detection, protection should be accomplished by a wet pipe
sprinkler system. Wet pipe sprinklers provide superior protection with little
maintenance.
5-4.3.1
Smoke Detection and Destratification Fans (Ceiling Fans).
The area of protection for smoke detection devices permitted by NFPA 72 must
be reduced by 50 percent where destratification (ceiling) fans are used (i.e., this
may require additional smoke detectors for that area being protected).
Exception: This restriction does not apply to thermal or flame detection devices
or to residential occupancies.
