NHX-80X

Central Control Unit

(CCU)

NHX Nurse Center

DESCRIPTION:

The NHX-80X is the control center of the
CommuniCare Nurse Call system, providing
microprocessor control of all calling and
communication functions of the system.

The NHX-80X provides system functions for one
master station, one duty station, and 50 patient
and/or common area call stations. System can
be expanded to 80 stations with additional trunk
card (NHR-30K) installed in NHX-80X.

Microprocessor based, the NHX-80X controls
different signaling levels from a bedside call
cord, bathroom call, or cordout status from a
patient station. Warning tones for disconnected
stations or off-hook condition at the master
station are also processed at the CCU.

The compact, wall mount design allows it to be
mounted in an equipment room or cabinet,
taking up little space.

All system wiring is terminated in the CCU with
“screwless terminals”. Wires are simply inserted
into each crimp connector for fast and easy
installation.

FEATURES:

• Microprocessor control of all system
functions

• Compact slimline design

• All wire terminations are made inside with
easy “screwless” wire connections

ARCHITECTS/ENGINEERS SPECIFICATIONS:

Central Control Unit shall be Aiphone model NHX­80X, equipped with power switch and concealed
status LED indicators, constructed of high-impact,
fire-retardant ABS plastic.

System capacity shall be 50 call stations, with
expansion capacity to 80 stations with model NHR­30K additional trunk card, installed inside NHX-80X.

All system functions shall be controlled from NHX­80X, including call signaling, communication, duty
station, and zone light control. The NHX-80X shall
detect if any patient station becomes disconnected
from the system or if the handset is left off-hook for
more than 90 seconds, and shall send a warning
tone to the master and duty station.

All system wiring shall be terminated inside NHX­80X with screwless wire connectors. Each trunkage
line from CCU shall contain up to 10 call stations
(NH-1SA, NH-2SA, NHR-3TS), wired in a daisy­chained fashion. System shall have a maximum of
eight (8) trunkage lines. Master station, duty station,
4-zone indicator light, and power supplies shall be
wired directly to NHX-80X.

Physical size of the CCU shall not exceed 18-1/8” x
13-3/8” x 3-7/8”. NHX-80X shall be mounted on UL
listed 3-gang box or inside UL listed electrical
enclosure. The size of the electrical enclosure shall
