Kalypso Emergency Bypass Option Instruction Manual 17
Installation
Control Cabling
Note Some early production models of the Kalypso Local Aux panel and 2-M/E
Main panel reversed the legends for the Emergency Bypass ports. Later
models had corrective labels applied at the factory. Current models are silk-
screened correctly. If after installation Emergency Bypass does not work on
an older system, try reversing these cables. Labels are provided (EBS MIXER,
EBS ROUTER) that can be cut out and affixed over incorrect legends. Ensure
proper system operation before relabeling the connectors.
Refer to Figure 8 .
• Connect an RS422 cable from the Emergency Bypass Mixer port on the
Local Aux panel or 2-M/E Main panel to the provided breakout serial
cable.
• Connect the multi-pin breakout connector to the serial port (J102) on
the rear of the Emergency Bypass frame, then connect the BNC break-
out connector to the J9 or J10 port of the slot where the Bypass Relay is
placed (typically slot 7). Do not terminate the open J9 or J10 port. It can
be used to control additional Bypass Relay modules. The BNC on the
breakout cable is used for contact closure only, and does not carry any
signal.
• Connect an RS422 cable from the Emergency Bypass Router port on the
Local Aux panel or 2-M/E Main panel to the serial port for the CIF
Module Option (ASYNC 1B) on the SMS 7000 MCPU/Controller
Frame.
Note The ground connection on the SMS 7000 serial connector is different. Please
refer to the SMS 7000 Installation Manual for cable details.
