NC110A Series Audible-Visual 50 LED Nurse-Call Master
The Alpha Communications® / TekTone® NC110A Audible Visual
Nurse Call Annunciator/Control Master provides for audible and
visual call indication without the use of intercom communications.
A basic nurse-call system may consist of an NC110A
annunciator/control master, room call stations, emergency call
stations, dome lights, zone lights, control unit and power supply
equipment. Emergency signals are identified at
the annunciator/control panel by a rapid flashing of the
associated station indicator LED, call LED and emergency LED; in
addition to a rapid pulsating tone. Routine calls are indicated by
the steady illumination of the station selector LED, call LED, and a
slow pulsating tone. The tone may be canceled for normal calls
by depressing the TONE ON/OFF button. EMERGENCY calls
take precedence over ROUTINE calls. Call signals can be canceled
at point of origin only. Tone on/off and tone test functions
are button selectable from the control panel, and three (3) levels
of tone volume are button selectable with LED indication.
Indicator LEDs signal the presence of EMERGENCY or ROUTINE
calls. The NC110A has a maximum capacity of 50 selector
points. Multiple NC110A masters may be used together for
larger system capacities. All selector LEDs, indicator LEDs and
control buttons are included on a membrane-type switch mounted
on a telephone-sized plastic housing. An N/O open isolated
relay contact output for ancillary off-board call handling is
also included.
