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.
