Sound Baffles
Some hang locations require a reduced noise environment. Fan noise in the VL7 luminaire and Series
200 luminaires can be greatly reduced by using the VL7 sound baffle kit, the VL2C sound baffle (with
or without sound blanket) and VL4 sound baffle.
No additional hardware is used to secure the sound baffles to the luminaires when the luminaires are
hung from trusses. The Series 200 sound baffles are secured to the luminaire with safety cables. For
ground installations, safety cables are not required. The VL7 sound baffle mounts over the top head
cover. For all uses of the sound baffles (and sound blanket), the baffle fits over the fan opening and air
filter. Note the following:
•
It is not necessary to remove the air filters from VL2C luminaires.
• It may be necessary to remove the air filters from VL4 luminaires in some cases.
VL7 Luminaire Sound Baffle
The VL7 sound baffle is a two piece kit consisting of the baffle itself which mounts over the top head
cover and is secured with elastic cords that wrap around the head assembly; and a thin counterweight
required to be installed inside the bottom cover to balance the head assembly.
