The NHX is a Health Care Communication System, exclusively designed for patient to staff
communications in health care facilities. The NHX system is UL Listed under UL1069 the Standard for
Hospital Signalling & Nurse Call Equipment. At Nurses Center, the NHX-50M master station is an
extremely compact, low profile console. Add-on 30-call selector can be plugged into NHX-50M. In each
room, single or dual-call Nurse Call bedside sub stations are used with corridor light and bathroom call
switch. The NHR-3TS is a common area or hallway sub station, which can be used with a NHR-7A
pullcord urgent call switch.
