Photoluminescent Area of Rescue Signs
This series consists of the following:
Model SN-LM42D
Model SN-LM42DR
Model SN-LM42S
Model SN-LM42SR
CAUTION:
In order for these signs to operate as intended,
the installed location MUST meet certain
minimum ambient lighting levels.
The SN-LM42 “Brilliance” Series Photoluminescent Signs provide a simple means to
provide illuminated signage for Area of Rescue Assistance / Area of Refuge applications.
Because they “Glow-in-the-Dark” upon power failure – using high-performance materials,
they do not require any field wiring.
This guide is intended to assist you in the installation of such signs.

• Drill Bits:
¼-inch Masonry Bit – for use with included anchors for concrete / mortar surfaces
¼-inch High-Speed Bit – for use with included anchors for drywall surfaces
3/32-inch Bit – where anchor screws will fasten directly into wood structure

STEP 1 - CHOOSE A LOCATION FOR EACH SIGN:
Locations and mounting heights for such signs are dependent upon local Building Code requirements.
If your project involves an Architect and/or Engineer – they should be able to provide guidance.
If your project is design / build, or if your firm is the only contractor – you need to familiarize yourself with
local Code requirements, and should probably consult with your local Authority Having Jurisdiction
(building inspector / Fire Department official with jurisdiction regarding Building Egress issues).
In order to ensure proper operation, Cornell SN-LM42 Series signs require the following minimum ambient
illumination:
• DEFINITION – In this case, “ambient” shall be defined to mean at all times when the building is occupied.
• MINIMUM AMBIENT ILLUMINATION = 54 lux on the face(s) of the sign
• LIGHT SOURCES = In order for the signs to function properly, the Ambient Illumination needs to be
within a certain range of the visible light spectrum. The best way to ensure this, is to be certain that the
Ambient Illumination Sources consist of one or more of the following:
Flourescent Light Fixtures / Bulbs
Metal Halide Light Fixtures / Bulbs
Mercury Vapor Light Fixtures / Bulbs
If you suspect that the light level at a proposed location is marginal, one way to know for sure is to check
with a light meter. (Be sure to use one that reads in lux units, is suitable for the lighting types being read,
and place and place the meter “eye” on the face of the sign, while holding it in the proposed location.)
If the illumination at a proposed location is provided via a variety of sources, be sure to temporarily turnoff, block, or cover any light sources that are not listed above when metering light levels (Incandescent
lamps / fixtures, windows, etc.).
STEP 2 - CHOOSE THE MOUNTING METHOD FOR EACH SIGN:
Cornell SN-LM42 Series signs may be mounted to the building structure via any of the following methods:
(Refer to the pictures below)
STEP 3 - APPLY DIRECTIONAL ARROWHEADS TO EACH SIGN:
Cornell SN-LM42 Series signs include a set of RED Arrowhead “Stickers”, which may be applied as needed
to each sign, such that where required – the sign will “point the way” to Areas of Refuge, as designated within
the building.
The procedure for application of these arrows is illustrated in the series of photographs included within Figure
3 (see next page).
Note: Cornell recommends applying the arrowheads to each sign prior to mounting it, because doing so
usually produces neater results
