NFBIC-5LMRATA 5" Fire Box IC AT Hsg Ded LED

Product Description

NFBIC-5LMRATA 5" Fire Box IC Air-Tight Housing (Dedicated LED) by Nora Lighting is a specification-grade, two-hour fire-rated new-construction housing. Its double-wall design with non-combustible fiber insulation helps prevent flame and smoke passage while dampening sound between floors—ideal for multifamily, hospitality, and commercial projects seeking code-compliant protection and reliable LED performance.

Product Benefits

• Code-compliant protection: two-hour fire rating helps maintain floor/ceiling assembly integrity.
• Energy-efficient envelope: Air-Tight gaskets reduce conditioned-air leakage.
• Sound dampening: non-combustible fiber fill minimizes noise transfer between levels.
• Fast, flexible installs: wide-spanning bar hangers, through-branch circuit wiring, and quick connectors.

Key Features

• Double-wall steel construction with non-combustible insulation
• Pre-wired junction box with multiple knockouts and snap-on covers
• Quick-connect terminals for power, neutral, and ground
• Listed wet location (with compatible trims/reflectors)
• Thermal protection rated 110 °C

Installation Tips

• Follow UL L500 Series assembly details; maintain manufacturer spacing: max 1 fixture / 25 sq ft and min 3 ft between fixtures.
• Use the included T-bar notch for suspended ceilings or align bar-hanger feet to joists for wood construction.
• Land conductors in the pre-wired junction box and use quick-connect terminals for line, neutral, and ground.
• Verify wet-location listing with the selected reflector/trim and seal ceiling interface as required.
• Always comply with local code and the project’s fire-resistance design.

Frequently Asked Questions

What makes this a “fire box” housing?
A double-wall, fiber-insulated construction provides a two-hour fire rating to help maintain the floor/ceiling assembly’s integrity.

Is this housing IC and Air-Tight?
Yes. It is IC rated for direct contact with insulation and has factory gaskets tested to <2 CFM per ASTM E283.

Can I use it in wet locations?
Yes, when paired with compatible reflectors/trims the housing is listed for wet locations.

How far apart should fixtures be spaced?
Follow the UL classification: no more than one fixture per 25 sq ft and maintain at least 3 ft between fixtures.

What ceiling types are supported?
Bar hangers adjust from 13-3/4" to 24-1/2" and include alignment feet for joists or T-bar grids; the housing fits ceilings up to 1-3/4" thick.

Does it support through-branch wiring?
Yes. The pre-wired junction box is rated for through-branch circuit connections.

Which LED modules or trims are compatible?
Use compatible Nora 5" reflectors/LED trims per project requirements (contact us if you want a curated list for your application).
