Sprinkler Info - Reliable G4FR

[Marshal Chris]

Hello all!

I have done an inspection in a adult community recently and uncovered a situation that I'm looking for some assistance. This particular building was constructed around 2000 and built to the NY "Green Book" code. During the inspection, we noticed a concealer cover plate that was different than the rest, so I checked it for compatibility with the head. It wasn't and I found it to be a standard response head (G4) but it was in the kitchen, so I decided to check a few heads in the dining room. I found them to be G4FR. I am almost positive these heads were never listed as a quick response head but a co-worker found some exceptions with regards to a fast response element of a certain RTI. I haven't been able to find any documentation about the RTI.

Does anyone know if this was allowed then? Thoughts?

Thanks!

Chris

This leads you to a PDF that lists the G4FR as a quick response. Are the glass bulbs 2MM or 4MM?

Also would call reliable tech support and ask the question

Any original plans laying around????

I'm assuming you mean this pdf:

I'm not seeing where it's listed as a Quick Response. I do see it's listed, just not QR.

The G4FR does offer faster thermal response for those applications where this is desired.

The Models G4, G4-300, G4FR, G4A and G4A-300 “Sealing” Concealer are standard response sprinklers. The G4FR, G4A and G4A-300 are not listed as quick response when the seal is used.

Call the maker

FYI, spoke to reliable tech support today. They confirmed my thoughts. G4FR never listed for QR.
