NC304 Master Station NC304LCD Master Station
NC304 and NC304LCD Master Stations
A major component of the NC300II system, the NC304 and NC304LCD Master Stations supply the user interface to respond to calls, issue staff requests and alter room programming status to accommodate different patient needs. The NC304 and NC304LCD are functionally the same, except the NC304LCD has an integral 2-line, 80-character LCD display for showing up to 4 active calls. The master station allows for room and staff communication by either open speaker or handset for additional privacy. A color VGA monitor (our model NC313) can be used (required for the NC304) to display up to 16 active patient, staff or duty calls (with page up and down feature) as well as columns for two (2) levels of staff presence and STAT priority call, in English language format.

Master station function buttons are provided to select the system functions as follows:

  • RESET (black) Terminates most operations.
  • AIDE (yellow) Enters an aide service request.
  • NURSE (green) Enters a nurse service request.
  • STAT (red) Enters an urgent staff emergency request.
  • MENU (blue) Displays function menu for programming additional features.
  • PAGE (gray) Initiates paging operations.
  • FOLLOW (orange) Initiates nurse-follower operations.
  • TALK (white) Press while speaking, release to listen when using loudspeaker for communications
  • ALPHA (white) Changes all function keys to the specifically labeled Alpha-characters.
  • MONITOR (blue) Page up.
  • CAPTURE (blue) Allows for zone assignment.
  • VIEW (blue) Page down.
  • PRIORITY (blue) Activates menu for changing room priority
  • TONE ON (white) Turns normal call-tone on/off. 
Additional programmable functions include set station priority, set privacy, zone assignments, view station configurations, set or reset code call stations, set password, reset time of day, time display, set overtime, transfer for master stations, paging, system configuration, and system re-initialization.

The master station is also equipped with volume control for adjustment of incoming voice communication; tone switch for controlling the lowest priority tone signal only; beep switch for controlling the short tone signal heard when the keypad is in use; call light with indication of low, medium and high priority calls; CPE fault LED; and alphanumeric keypad used for entry of station numbers, zone and station selection, and for selection of menu functions.

The master station(s) also provide a parallel port and serial port for connection to UL1069® Listed devices. The system programming is accessible to the user via the keys on the master station or via the keyboard port which will accept any standard PC keyboard (similar to our model KB-1).
