Gas Sensor  

Description  more details

  • Wall or Duct mounted Toxic Gas safety monitor.
  • Monitors CO, NO2, O2, H2, H2S, CH4, C3H8 ( each gas requires a separate unit )
  • 85 dB audible alarm and LED visual alarms
  • Built in relay to initiate further action
  • Advanced electrochemical (for toxic gases)and catalytic bead (for combustible gases) sensor performance
  • Network version on this page Connects to digital systems
  • Works with virtually any BAS including BACnet, Modbus or LonWorks
  • Connects to wired or wireless system (via 301CW wireless controller)
  • Cost Effective:
  • Saves energy through Demand Control Ventilation (DCV)
  • Optimizes BAS, fire, ventilation and other security systems
  • Versatile Communications:
  • Works through BAS to improve fault diagnostics and collect data on gas concentration levels, sensor condition, etc.
