If I have a machine with a carbon dioxide extinguishing system in a room equipped with an automatic sprinkler system.
Does the carbon dioxide system panel need to be tied into main fire alarm control panel? Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

Rephrasing the question for a cleaner answer - Does the alarms from CO2 Fire Extinguishing System Panel need to be connected to the Building's Fire Alarm System Control Panel?

Fully agree

To second what Glenn said after cleaning up the question, yep.

Echoing Gleen, the panel should be tied into the fire alarm system.

I don’t have a code quote for you but I’ve got a lot of metal cutting machines in F occupancies that have CO2, for optional protection. They are not required to be monitored. They have been evaluated for the hazard and the CO2 is a precaution only.

To be clear there is no control panel in my example, just an air line that if melts, trips the bottle. No electronics involved (of course you can add an output to them)

This is an autonomous gas protection system. They are also often provided inside electrical cabinets in Europe.

Generally speaking no, the systems aren't required to be monitored. Local Application systems such as this are technically secondary systems and are usually not required. Of course, they are a pretty good idea because if you have a fire inside one of the machines the fire is contained to a part of the machine or just one machine rather than a whole production floor. Monitoring it is also a good idea because when these systems work they will often fully extinguish the fire. Imagine this happens when no one is on site and then you walk in the morning and while the fire is out you had no idea there was a fire yesterday. I have a property that I service that has 50 CNC machines with the type of system you describe (manufactured by Firetrace). The building is fully sprinklered. If the local application system fails, the building and occupants are protected but the sprinkler system may cause damage to the other equipment (the stuff that wasn't on fire). 5/25/2023 09:04:03 am
The requirement to tie in a fire suppression control panel (in this case the one controling the CO2 system) into the building FACP is found in Chapter 23 of NFPA 72 along with other requirements for this situation. Leave a Reply. |
