Voltage Interface Unit


The NC375 (NC-375) Voltage Interface Unit will integrate TekTone's Tek-CARE® NC110, NC200, NC150 Nurse Call Systems and CM800 Emergency Call Systems with TekTone®'s on-site paging transmitter model NC366A. The NC375 will accommodate a 128-station system, and is connected directly to the nurse call master or emergency call annunciator panel. Up to 3 NC375s may be connected to the NC366A to increase capacity to 384 stations.

The NC375 interface sends call priority information via a serial port to the NC366A on-site UHF transmitter. The transmitter then transmits this information to the pagers, allowing the staff to distinguish call priority levels. The NC37D's ability to accept analog inputs and turn them into serial data, and the ease of installation and connection, allows the integration of radio-paging and management systems to TekTone® non-microprocessor-based nurse call and emergency call systems. Contact the factory for applications using non-TekTone® systems.
