ARCHITECTS/ENGINEERS SPECIFICATIONS:
Central Control Unit shall be Aiphone model NHX-
80X, 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 NHR-
30K additional trunk card, installed inside NHX-80X.
All system functions shall be controlled from NHX-
80X, 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 NHX-
80X 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 daisy-
chained 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
be more than 23-3/4” x 19-3/4” x 4”, with a secured
door and a suitable non-combustible mounting
surface inside the enclosure.
Equipment shall be UL 1069 listed, and system
components shall be provided by a manufacturer
having ISO 9001 certification for quality standards.
