Hospitality & Multifamily Application Feature: Units & Guestrooms
*
Insights
Units & Guestrooms have a unique set of features that specifiers must design
around to balance function, comfort, and code.
Price: All construction projects have a budget and as Multifamily Units & Hotel
Guestrooms comprise a high quantity of lighting fixtures in mixed-use spaces
they can often be the most cost-sensitive spaces to design.
Fire Rating: Fire Rating is a code requirement specific to many wood-built
structures in which individual living spaces or guestrooms are accessed via
common corridors, stairways, and exit doors. These common passageways should be
constructed to provide approved levels of fire protection enabling occupant
egress in the case of an emergency. There are several methods of installing a
light fixture without sacrificing the fire rating of floor or ceiling assembly
but these methods can be labor-intensive and costly. Fire-rated fixtures
simplify the design and construction of these spaces.
Sound Rating: Don’t you hate it when noisy neighbors disrupt the peace in your
home or getaway lodging? As building finish trends have recently moved away
from using carpet in favor of more laminated type products this issue is more
pronounced than ever. That’s why sound-rated luminaires are an important
component in the design of any building: to minimize sound transmission from one
room to the next. Minimizing the transmission of noise from adjacent rooms
requires judicious choice of many building components such as floor topping,
floor underlayment, subfloor topping, subfloor underlayment, ceiling insulation,
joist size, resilient channel, ceiling finish, construction quality, and a
sound-rated luminaire.
Non-Conductive (Dead Front): The term dead-front is defined by the National
Electric Code (NEC) as “without live parts exposed to a person on the operating
side of the equipment” and usually is specific to electrical panels. Some
jurisdictions like the City of Seattle go one step further and require all
“luminaires, with exposed metal parts that are grounded, must be ground fault
circuit interrupter protected.” The requirement to add GFI protection to the
luminaire circuit within the shower or bathtub zone adds complexity and cost.
However, dead front trims are constructed out of non-conductive polycarbonate.
Contractors and designers alike prefer these trims as a cost and time-efficient
way of overcoming the GFI requirement, which is only applicable to grounded
metal trims.
Closet Rating: Due to their unique usage, closets, and storage spaces demand
special electrical code requirements outlined by the (NEC). Luminaires in
clothes closets must be (1) Surface-mounted or recessed incandescent or LED
luminaires with completely enclosed light sources (2) surface-mounted or
recessed fluorescent luminaires or (3) Surface-Mounted fluorescent or LED
luminaires identified as suitable for installation within the close storage
space. These permitted luminaire types must meet minimum clearance
requirements. Depending on the lighting type, the space between the fixtures
and the closet contents requires up to 12″ of clearance and if that is not
available, the fixtures must pass the UL Closet Rating Test in compliance with
standards UL 2108, 67.1.9, and 60.4.
Warm Dim: Warm dim technology gives occupants the flexibility to choose the
light that’s right for them by dimming from vibrant, full-spectrum lighting, to
a warm, comfortable glow. There’s minimal color temperature change at the high
end of the dimming curve so daytime lighting remains vibrant and unaffected.
Once dimmed below 50% light output, the color temperature gradually warms to
provide the personal, intimate ambiance desired in the evening.
Tunable White: Tunable white is becoming increasingly trendy in high-end hotels
and living spaces as it grants the occupants full autonomy to choose the
specific color temperature of their lights and quickly change as desired.
Comprised of multiple LEDs of different color temperatures, you can control the
mix of these LEDs as well as intensity using a lighting control system of your
choice. Tunable white can be programmed to mimic natural daylight patterns,
supporting occupants’ circadian rhythm. This feature is important to hotel
guests with jet lag or those in senior living facilities without outdoor
mobility. Tunable white fixtures also allow for the ultimate task flexibility
in a living space as you can choose the color temperature ideal as you move
throughout the motions of your day whether it be working, cleaning, or relaxing.

Technical Bulletin: Fire-Rated Assemblies
*
Innovation
WHAT IS A FIRE-RATING?
Many people live in multi-family homes where individual living spaces are
accessed via common corridors, stairways, and entry/exit doors. These common
entry/exit passageways are constructed to provide approved levels of fire
protection that enable occupants to safely exit the building in case of an
emergency. DMF Lighting’s M Series, H Series, and DRD5S Series offer housing
options with a two-hour fire rating, suitable for common entry/exit passageway
applications when a fire rating is required. *Other fire barriers or methods of
protection maybe utilized, such as a concrete structure or a sprinkler system.
See the following product codes for more information:
M Series: M4NCRF, M4NCSF, M4LTRF, M4LORF, M4LTSF, M4LOSF
H Series: H3FR, F4NC
DRD5S Series: F4NC
WHAT IS THE IBC?
The International Building Code® (IBC), developed by the International Code
Council (ICC), is a model building code adopted and used as a base code standard
throughout most of the USA. The IBC® is a complex and lengthy document with
comprehensive requirements. Chapter 7 on Fire and Smoke Protection Features is
key, and in particular Section 714 Penetrations: The provisions of this section
shall govern the materials and methods of construction used to protect through
penetrations and membrane penetrations of horizontal assemblies and
fire-resistance-rated wall assemblies. Penetrations of ceiling membranes are
covered in Section 714.5 where subsection 714.5.2 Membrane Penetrations states:
Where floor/ceiling assemblies are required to have a fire-resistance rating,
recessed fixtures shall be installed such that the required fire resistance will
not be reduced.
How can a recessed fixture be installed without reducing the fire rating of the
floor/ceiling assembly? The traditional approach is shown above.
Although this is an effective method, it requires the ceiling space to have
boxed-out cavities, using the same fire-rated membrane material, to mount the
recessed fixtures in. This approach adds significant costs and requires extra
space above the ceiling plane that may not always be available.
The M Series, H Series, & DRD5S family, fire-rated housings provide a new method
of achieving the same result and is shown above.
DMF fire-rated junction box solutions reduce installation costs significantly
because they eliminate the requirement to create boxed-out cavities at the time
of construction by utilizing one of the exceptions provided by subsection
714.5.2: Ceiling membrane penetrations of maximum 2-hour horizontal assemblies
by steel electrical boxes that do not exceed 16 square inches (10,323 mm²) in
area, provided the aggregate area of such penetrations does not exceed 100
square inches (44,500 mm²) in any 100 square feet (9.29 m²) of ceiling area, and
the annular space between the ceiling membrane and the box does not exceed 1/8
inch (3.2 mm).
DMF fire-rated junction box solutions reduce installation costs significantly
because they eliminate the requirement to create boxed-out cavities at the time
of construction by utilizing one of the exceptions provided by subsection
714.5.2: Ceiling membrane penetrations of maximum 2-hour horizontal assemblies
by steel electrical boxes that do not exceed 16 square inches (10,323 mm²) in
area, provided the aggregate area of such penetrations does not exceed 100
square inches (44,500 mm²) in any 100 square feet (9.29 m²) of ceiling area, and
the annular space between the ceiling membrane and the box does not exceed 1/8
inch (3.2 mm).
UL 514A STANDARD FOR SAFETY – METALLIC OUTLET BOXES
One of the many UL listings DMF M Series, H3FR, and F4NC housings has been
granted is QCIT.E469361. This UL listing states that each of these housings is a
qualified metallic outlet box or in IBC terminology, steel electrical box. UL’s
Fire-resistance Ratings – ANSI/UL 263 BXUV.GuideInfo states in section III –
Floor-Ceilings and Roof-Ceilings, sub-section 6 – Metallic Electrical Outlet
Boxes, can be used in fire-rated floor-ceiling and roof-ceiling assemblies, as
described below:
Metallic outlet and switch boxes with metallic or nonmetallic cover plates may
be used in floor-ceiling and roof-ceiling assemblies with ratings not exceeding
2 hours. These assemblies should have gypsum wallboard membranes. The metallic
outlet boxes should be securely fastened to the joists and the opening in the
gypsum board facing should be cut so that the clearance between the boxes and
the gypsum board does not exceed 1/8 in. The surface area of individual boxes
should not exceed 16 sq in. The aggregate surface area of the boxes does not
exceed 100 sq in per 100 sq ft of ceiling surface.
Note the requirement for the contractor to create a tight, not to exceed 1/8”
cut-out in the gypsum wallboard to ensure the integrity of the fire-rated
membrane.
MORE THAN JUST FIRE-RATED
