Installing Sound Baffles
Some hang locations require a reduced noise environment. Fan noise in
luminaires can be greatly reduced by using the VL2B/VL2C luminaire
sound baffle (with or without sound blanket).
No additional hardware is used to secure the sound baffles to the
luminaires when the luminaires are hung from trusses. The sound baffles
are secured to the luminaire with safety cables. For ground installations,
safety cables are not required. For all uses of the sound baffle, the baffle
fits over the fan opening and air filter. It is not necessary to remove the air
filter from VL2B and VL2C luminaires before installation.
