Is it required for a commercial kitchen fire suppression system to be monitored by the fire alarm system?
A commercial kitchen fire suppression system works when either a cable is pulled (manually), as the video shows below, or with a fusible link detection. Activation of either will release an agent throughout the hood, duct, and onto the appliances. Is it a code requirement to have this suppression system monitored by a fire alarm system? To find the answer, we can first consult NFPA 72 on this matter:
NFPA 72 188.8.131.52.1 – Where required by other governing laws, codes, or standards to be monitored and a building fire alarm system is installed, the actuation of a fire suppression system shall annunciate an alarm or supervisory condition at the building fire alarm control unit.
So NFPA 72 tells us that when required by other codes or standards, activation of such system (fire suppression) shall annunciate an alarm or supervisory condition at the building fire alarm control panel. To fully answer the questions, we need to consult IBC (International Building Code).
IBC 2012 904.3.5 – Monitoring. Where a building fire alarm system is installed, automatic fire extinguishing systems shall be monitored by the building fire alarm system in accordance with NFPA 72.
IBC requires that when a fire alarm system exists, fire extinguishing systems shall be monitored by the fire alarm system as per NFPA 72.
