TekTone®’s NC110A Audible-Visual Nurse Call Annunciator/
Control Panel 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
panel, 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 routine
calls by depressing the tone on/off button.
Emergency calls take precedence over Routine calls.
Emergency 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 levels of tone volume
are button selectable with LED indication. Indicator LEDs
signal the presence of Emergency or Routine calls. The
NC110A has a capacity of 50 selector points. All selector
LEDs, indicator LEDs and control buttons are included on
a membrane-type switch mounted on a telephone-sized
plastic housing.  A normally open isolated relay contact
output for an ancillary off-board call handling is also included.
UL® 1069 listed; UL® File Number E71599.
