Switch Alarm Control Board (CT-156)
The board consists of three (3) sections.
• The input board switching section operating according to
programs
• The switching data producing section which operates
based on the alarm input signals.
• The reference signal processing section which serves to
synchronize the total system
Input/Output-Board Connector Board
The connector board accommodates the input/output
boards (available at option).
Power Supply Relay Board
The board relays AC mains and system control signals.
Meanwhile, it produces line-lock signals.
Signal Input/Output Boards
The boards are connector boards for various signals. The
signals are VIDEO IN/OUT, ALARM IN/OUT, EXT
TIMING IN, KBD I/F, SYNC IN/OUT, RS-232C,
PRINTER, VGA, KBD, MOUSE, and so on.
