FCS - Operation Manual
2 INTRODUCTION
2.1 General Description
NOTE:
If you are looking for information about installing and wiring the FCS Flexible Control
System, please find the Installation Manual on our website.
Thank you for purchasing our FSC Flexible Control System. The FCS Flexible Control System
is a sophisticated, high performance controller that offers multi-channel configurations for
monitoring toxic, combustible and refrigerant gases with versatile control functionality for
non-hazardous, non-explosion rated, commercial and light industrial applications. The FCS is
designed to accept inputs from digital and/or analog transmitters and/or Peripheral Devices
(in various combinations), using Modbus® RTU RS-485 or 4-20 mA analog input.
The FCS is available in 4 channel, 8 channel, 32 channel and 128 channel models with
either Modbus® RTU RS-485 WAN output or with BACnet® MS/TP RS-485 WAN output for
communicating with a Building Automation System (BAS).
All models include, four configurable SPDT dry contact relays with field configurable time
delays and trigger levels, a full colour LCD resistive touch screen with LED panel indicating
configurable channel alarm status, relay status and fault conditions, extensive menu system
with password protection, enhanced logic control, priorities/zoning capabilities, a USB port
for firmware upgrades, data logging and a door-mounted, audible alarm. The FCS has flexible
configuration settings for analog outputs and supports 4-20 mA and Modbus® driven VFDs.
2.2 Key Features
