NHX Nurse Center
NHX-50M
Master Station
DESCRIPTION:
The NHX-50M Master Station is the central point
of the CommuniCare system, able to receive
two levels of calls and communicate with up to
50 room stations. The optional 30-call add-on
selector allows expansion up to 80 stations. The
membrane-style control panel is simple to use,
has tactile switches, and is mar-resistant and
moisture-resistant, resisting damage from spills.
The master station includes a handset for voice
actuated communication, with a magnetic
hookswitch (no moving parts). Controls include
TALK button for “push-to-talk” communication,
TONE OFF button to silence call tone, and OFF
button to conclude communication. Easily
adjustable voice and tone volume controls are
located on the side, with all other volume
controls located on the bottom of the unit.
OPERATION:
Routine calls are annunciated with a slow
flashing LED and an intermittent call tone. Calls
from a bath station annunciate a faster flashing
LED and faster tone. Bedside cord pulled out
of patient station sounds rapid tone and activates
fast flashing LED. Pick up the handset or press
TALK to answer, and the highest priority call will
be automatically connected. Hang up handset
or press OFF to conclude. To initiate a call,
press the room station selector button and TALK
button, or pick up handset. Bathroom calls have
priority over routine calls, and will be answered
first. Otherwise, calls will be answered in the
order received.
