High performance Controller with logic and priority settings for monitoring toxic, combustible and refrigerant gases with versatile control functionality. Available with Modbus® or BACnet® communication with BAS, supports 4-20 mA and Modbus® driven VFDs.


  • Up to 128 channels of gas readings
  • Graphic, full colour, resistive touch LCD display with LED indicators
  • Enhanced logic control, zoning and priorities capabilities


The FCS Flexible Control System is a sophisticated, high performance system controller that offers up to 128 gas channel configurations for monitoring toxic, combustible or 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 Flexible Control system is available in two models: the FCS-M with Modbus® RTU RS-485 output or the FCS-B with BACnet® MS/TP RS-485 output for communicating with a Building Automation System (BAS).

Standard features include, 4 internal SPDT dry contact relays, a full colour LCD resistive touch screen with an LED panel indicating channel alarm status, relay status and fault conditions, an 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.

Optional value added features include, analog inputs and/or analog outputs, a top mounted strobe, a locking door, manual shut off switch, and a water tight audible alarm.
