Cooper Lighting Envoy - Manual (Page 9)

P E N D A N T M O U N T A P P L I C A T I O N S
Garage fixtures are commonly mounted to pendant pipes to bring the light source closer to ground level to achieve increased light levels. Many times
this is desirable due to higher ceiling heights or structural supports at the ceiling level that interfere and block light emitted from the luminaire. Envoy
offers multiple pendant mount solutions. When a bird nesting deterrent is required in pendant applications, use the [PBG] accessory.

A C C E S S O R Y [OFFSET POSITION]
Envoy is attached to the pendant box [PBG]
accessory using the standard quick mount
release bracket system. The pendant
conduit pipe and free swing swivel hanger
system are provided by others. Because
the system is free swinging, the offset
pipe position must be used to allow the
fixture to hang straight.

[CENTER or OFFSET POSITION]
Envoy is attached to the pendant box [PBG]
accessory using the standard quick mount
release bracket system. The pendant
conduit pipe and suspension mechanism
are provided by others. Because the
system is rigid and non-moving, the
center or offset pipe position may be used
to hang the fixture.

[CENTER POSITION]
Envoy is attached to a 4" junction box
using the standard quick mount release
bracket system. The pendant conduit
pipe and junction box with center
pendant entry access are provided by
others. The center position of the J-Box
may be used to hang the fixture.

In typical double-T structural ceiling designs, the luminaire is placed between 2 beams that are no more than 4 feet apart. In a surface mount
scenario this method traps a significant amount of light within the ceiling structure, leading to compromised light levels on the work plane.

Ceiling
When designing for T structure ceilings, the optimal
solution is to mount the fixture via pendant pipe at or
below the bottom plane of the beam level. Since beams
typically traverse laterally along the width of the garage,
using the rectangular [TG] distribution in the same
direction generally offers the best solution.
