Lowell’s KL Series volume controls feature a keylock instead of a knob to perform volume level adjustments. This patented Lowell design provides systems administrators with secured settings for volume level of critical paging and/or emergency systems. Additionally, these controls are advantageous for maintaining comfortable listening levels for music, paging, or masking in health clubs, entertainment and retail facilities, schools and offices of all kinds. The Decora®-style (two-piece) plates are available in plastic (white, ivory or black) or with a stainless steel coverplate and a plastic (white or black) subplate. They are compact, 1-gang Decora® style (two-piece) plate assemblies with a 100W power rating. They all include easy to connect, phoenix-style plug-in screw termination strips for pre-wire convenience with wire capacity up to 14gauge. Attenuation is 3dB per step.
