Do I require a FRR for my generator room?
Answer (natural language)
Yes. If your generator supplies emergency power for lighting, fire safety, or life safety systems, it must be located in a room with a fire separation having a fire-resistance rating (FRR) not less than 2 hours. This applies unless the building is used solely to house the generator and its ancillary equipment.
Full Quoted Code Text — Sentence 3.6.2.8.(1)
“Where a generator intended to supply emergency power for lighting, fire safety and life safety systems is located in a building, except where such building is used solely for the purpose of housing the generator and its ancillary equipment, it shall be located in a room that
(a) is separated from the remainder of the building by a fire separation having a fire-resistance rating not less than 2 h, and
(b) contains only the generating set and equipment related to the emergency power supply system.”
