Comrex 9900-0025 STAC12 Extra Control Surface

One control surface is included with purchase of mainframe. Additional control surfaces, up to four per system, may be added at any time. STAC6 control surfaces can be upgraded to STAC12 in the field.

Clean, logical design allows functions to be mastered quickly. Dedicated buttons, with associated multicolor LEDs, minimize the number of button presses and make it easy to determine status of phone lines and callers.

Any control surface can operate in Studio/Producer or Screener Mode. Designed to use standard Cat-5 wiring to link the control surfaces to the mainframe up to 100 feet away. No proprietary cabling or additional power source required for control surface connection.

Features:

• Functions available in ALL modes:
• Auto-Attendant activation, deactivation.
• Default Priority for next caller to be placed on air is:
• Callers on hold who have been screened,
• Followed by callers on hold who have not been screened, in order of length of time on hold.
• Change Priority function overrides the default priority to select and indicate the next caller to be to be placed on the air.
• Busy All function assists in "clearing the phones" for contests and other uses. Pressed once, the Busy All button drops all unlocked lines and will "busy them out". On second press, the unlocked lines are freed up and are now available to receive calls.
• Aux button controls logic output to turn on/off external recorder or delay. DIP switch configurable as momentary or latching. The Aux function on each control surface operates independently of the others. In Studio/Producer mode, this button may alternately operate as a "Next" button, seamlessly putting the next priority line on the air.
• Jack provided for headset connection to provide alternative to handset.
  
  
• Screener Mode Functions
• The top row of buttons performs off-air call answering, including placing calls on hold or releasing them. Callers selected from these controls communicate via the control surface handset. Bicolor green/yellow LEDs indicate whether the line was answered at this control surface or another.
• The middle row of buttons is used to signal screening status to studio/producer control consoles, place callers on hold and to change priority. A screener cannot place callers on air. Bicolor red/blue LEDs indicate which lines are on hold, which lines are on screened hold, and priority status.
• The bottom row of buttons drops lines that have been selected using the top row of buttons.
  
  
• Studio/Producer Mode Functions
• The top row of buttons performs off-air call answering, including placing calls on hold or releasing them. Callers selected from these controls communicate via the control surface handset. Bicolor green/yellow LEDs indicate hold and priority status.
• The middle row of buttons places callers on air, with or without screening. Lines will drop when another caller is selected. Alternately, by pressing the corresponding line button a second time, the line may be locked for conferencing and requires pressing the drop button to disconnect. Bicolor red/blue LEDs indicate which lines are on air, to which hybrid the lines are assigned, and whether the line is locked on air.
• The bottom row of buttons drops lines that have been selected from either the top or middle row.
