I am a municipal fire inspector. We have a new high school, fully sprinklered, that has residential stoves in a classroom. These are protected with UL300A hoods.
Are these hoods required to be connected to the fire alarm? Common sense would indicate that if there was a fire hot enough to release the UL300A system, that the building occupants could be in danger and the fire alarms should activate, however, I cannot find a code reference for this. The architect is saying the stoves are residential so only residential requirements apply. Submitted anonymously and posted for discussion. Discuss This | Submit Your Question | Subscribe

The systems shall be monitored. The application is not for a residential use, but for public use!

It's not residential it is E occupancy.

2017 NFPA 96 10.6.2 states “Where a fire alarm signaling system is serving the occupancy where the extinguishing system is located, the activation of the automatic fire-extinguishing system shall activate the fire alarm signaling system.

If your jurisdiction subscribes to any fire code derived from the IFC, please see Section 904.3.5.

The jurisdiction that I work for has allowed several of these to be installed. The intent of allowing the UL 300A type of hood with a built-in preengineered suppression system is to fulfill the requirements NFPA 96, and allow the residential range be installed with a residential type of hood. This includes the fire alarm requirement of NFPA 96 if a fire alarm exists. Most of the systems have a pair of dry contacts that is a relay to be tied to the fire alarm.

Look at IFC Section 904.3, specifically 904.3.5

Thank you to each of you for the input. That helped point us in the right direction. Our jurisdiction uses the IFC along with the Ohio Fire Code. We are going with those (904.3.5 in both) as well as NFPA 72 Section 17.14. The NFPA 96 comments above were also right on the money and an area we did not see before. The Scope 1.1.1 and 1.1.2 have wording that apply specifically and exactly as well as 10.6.2 mentioned above. We appreciate the research help. Leave a Reply. |
