LC-040 Low Voltage Controller

100-130V Low Voltage Controller for Four-Gang
or Larger Masonry Box Applications

The LC-040 enables users to safely operate the high-voltage lighting found in hospital and nursing home rooms with their pillow speaker or bed communication side rail. It’s tested and approved for use with all Nurse Call systems that use a momentary normally open switch for auxiliaries, and is designed for applications using a four-gang or larger masonry box.
