FIREFINDER SERIES II INSTALLATION, COMMISSIONING &
OPERATION
11.13.2 Local Control Station (BRD25ARB-B)
The Local Control Station (LCS) 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
