Local Control Station Layout
The Local Control Station is supplied with its own mounting panel. The Comms line is RS485 between the
Local Control Station and the Main Control Board.
The Interlock is a monitored input with 10K
Ω
EOL used to determine if air conditioning dampers and doors
are closed. Typically the agent is not discharged until all dampers / doors are closed but can be defaulted
to the “ON” condition by terminating the input with a 2K2
Ω
as shown below.
