904.1.1 Fire extinguisher system design.
Fire extinguishing systems may be engineered or pre-engineered. Pre-engineered systems shall be of a type for which a certificate of approval has been issued in accordance with FC 112 and 901.4.5. Except as otherwise provided in this code or other applicable law, rule, regulation or standard, fire extinguishing systems may be designed as local applications or as total flooding systems. All activation devices and other system components shall be listed and installed in accordance with the listing and the manufacturer's instructions.
904.1.2 Installation acceptance testing.
All fire extinguishing systems shall be subject to acceptance test conducted at the owner's risk by his or her representative before a representative of the department. The owner's representative shall furnish the necessary equipment required to conduct the test. A discharge test may be required as set forth in the applicable installation standard or as required by the department when there is evidence that the system will not provide the necessary level of protection.
904.1.3 Additional safeguards.
If an area is protected by a fire extinguishing system which uses an extinguishing agent that will make the protected area hazardous by its discharge or thermal decomposition, suitable safeguards shall be provided to ensure prompt evacuation, to prevent entry into such atmospheres, and to provide means for prompt rescue of any trapped personnel. Such safeguards shall include establishment of a trained brigade, equipped with and qualified in the use of self-contained breathing apparatus with 30-minute minimum supply, for prompt search of the protected area.
Exception: Self-contained breathing apparatus shall not be required for a clean agent fire extinguishing system installation if:
1. The installation is provided with an alarm system that is connected to an approved central station.
2. The protected area is provided with an approved fixed emergency forced ventilation system able to expel the extinguishing agent. Such emergency forced ventilation system shall have a capacity sufficient to effect at least twenty air changes per hour.
3. The protected area is of a size, design and/or occupied in such a manner that egress will not be impeded.
4. The protected area is not normally occupied by any individual requiring assistance in evacuation.
904.1.4 Prohibited fire extinguishing systems.
It shall be unlawful to install carbon dioxide, halon and clean agent fire extinguishing systems as set forth in FC 904.1.4.1 through 904.1.4.3.
