Low Voltage Controllers enable users to safely operate the high-voltage lighting found in hospital and nursing home rooms with their pillow speaker or bed communication side rail. They’re tested and approved for use with all nurse call systems that use a switch with normally-open momentary dry contacts for auxiliaries.


  • True universal voltage (120 to 277 VAC)
  • For use with fluorescent, LED, and other lamp types
  • Controls two loads independently, or two loads sequentially
  • Safe for use near medical equipment that is sensitive to electromagnetic noise
  • Can be used to operate high-voltage circuits such as lights, electric doors, and drapes
  • Can be controlled from a pillow speaker, bed side rail, or wall switch with normally-open momentary dry contacts
  • Patent Pending
  • UL/C-UL Listed to UL 508 • Compliant with FCC, Title 47 CFR 15 – Class B • RoHS compliant
  • Industry-leading three year warranty
