The central equipment shall be Alpha Communications®/Tektone
NC260B, or approved equal, and shall be supervised (trouble indi-
cations shall be annunciated at the designated NC250 Nurse Master
Station.) The NC260B shall provide all of the microcontroller
technology necessary to operate all NC205 Nurse Call System
functions. It shall interface with up to four (4) NC250 Masters, up
to 64 station point connections (with two PM261A - 32 station
selector modules installed), and all other emergency and presence
stations associated with the NC205 Nurse Call system. The
NC260B shall also provide the necessary hardware to connect to
the NC262A Central Equipment Expander(s) to allow the system
to expand to a maximum of 128 stations. Connections shall also
be available to allow the (optional) battery backup (model BA002K).
The central equipment shall include one central processing module
and connection points for two (2) PM261A Selector Modules for
connection to patient/staff/duty stations, emergency switches, and
dome lights. A power supply to operate all internal circuits, nurse
master stations, patient/staff/duty stations, emergency switches, and
dome lights shall be included.
