Notice Reports: Passive Fire Protection CSI Specifications

These Architect & MEP Engineering Notice Reports translate FRPS fire-rated enclosures into ready-to-use CSI 3-Part Specification language for recessed lighting, troffer/LED lay-in panels, shower valve penetrations, exhaust fans, mini-split cassettes, and fan coil units.

Each notice report identifies the applicable IBC code sections, ASTM/UL testing standards, and FRPS-listed systems required to maintain fire-resistance ratings — giving architects, MEP engineers, contractors, and code officials specification language they can drop directly into project manuals and submittal packages.

Fire-Rated Composite Troffer / LED Lay-In Panel Enclosure

Our lightweight, patent-pending composite enclosures are built specifically for troffer and LED lay-in panel fixtures in T-grid suspended ceilings, ASTM E84 Class A tested for plenum use. This report includes a full list of compatible UL-listed ceiling assemblies for projects that need to match a specific listing.

Fire-Rated Composite Enclosures for Recessed Fixtures

Specifying troffers, LED downlights, or in-ceiling speakers in a fire-rated ceiling? This spec covers FRPS’s patent-pending composite enclosure, which folds together on site with no drilling or sealant. Includes ready-to-use CSI language for both the firestopping and electrical divisions, plus fire, thermal, and acoustic test data.

Fire-Rated Shower Valve Penetration Protection

Covers the FRPS enclosure and gap-fill gasket for shower and tub valves in a fire-rated wall, Intertek-listed for 1- and 2-hour assemblies. Also includes guidance on which drywall types are actually safe to use behind tile in a wet area — moisture-resistant board alone often isn't enough.

Fire-Resistance Requirements for Exhaust Fan Penetrations

A 2013 UL/Intertek rule change means a radiation damper alone often no longer qualifies a bath or exhaust fan for a wood-framed fire-rated ceiling. This report explains what changed and specifies the FRPS enclosure that restores the required rating without relying on the damper.

Fire-Rated Mini-Split Cassette / FCU Penetration Coordination

A ceiling-recessed mini-split or fan coil unit brings refrigerant lines, condensate drains, and electrical feeds through a fire-rated membrane all at once. This report breaks down responsibilities across architecture, HVAC, electrical, and plumbing, and corrects a common misconception — this is a membrane-breach issue, not a heat issue.

Fire-Rated Sheetmetal Enclosures for Recessed Devices

Our 24-gauge galvanized sheetmetal enclosures are sized and listed for fire-rated walls and ceilings — including downlights, speakers, shower valves, exhaust fans, and other common applications. The report includes ready-to-use spec language, a field checklist of non-compliant conditions, and submittal/closeout requirements for each trade.
