12.16.3 Local Control Station
The Local Control Station is supplied fitted into an IP40 rated enclosure and has the same indicators
and Manual Release switch as the Agent Release Module within the Fire Alarm Control Panel (FACP)
but no Agent Select button or Service Inhibit keyswitch.
The Comms line is RS485 and is cabled to the Agent Termination Board.
The Interlock is a monitored input with 10KΩ EOL. This input is used to determine if air conditioning
dampers and doors are closed but can be defaulted to the “ON” condition by terminating the input with
a 2K2Ω EOL.
Double action switching is achieved by way of protective lift up covers seen here and manual
operation of the MCP or Inhibit switch. To ensure correct operation and prevent accidental release of
the agent these covers should not be disabled for any reason

LCS Operation & Controls
Lifting the cover and pressing the MCP starts the manual agent release sequence. This two action
safety feature prevents any accidental operation of the control and should not be disabled.
