The EC50 gas detection electronic control centre is used for the detection of gas within industrial environments. Natural gas, town gas, LPG and cylinder gas can be detected using the various sensors available. This unit will provide gas detection for five separate zones.

  • Visual LED indication for five separate zones
  • Internal audible alarm
  • Adjustable alarm time delay
  • Din Mounting
  • Insulated enclosure
  • Two SPDT relays for use of closing the gas solenoid valve and BMS alarms
  • Alarm delay setting – up to 60 seconds
  • Complies with CEI EN 60730-1 standards
  • 230v 50Hz or

When the presents of gas exceeds established levels (below L.E.L) the EC50 gas detection electronic controls centre will go into the alarm state. This will automatically close the gas solenoid valve, operate the audible and visual alarms on the gas detection unit as well as activating any remote or BMS signals utalised by the SPDT relays. Five different gas type sensors can be used with this multi zone gas detection unit.


Detection heads

Detection heads

These gas sensor heads are to be used with either EC30 or EC50 gas detection units. There are two types available, the EC71 for natural gas and light gas, the EC72 for LPG heavy gases. The sensor for alarm is set below the L.E.L level (Lower Explosion Limit) however there is internal regulation for the sensitivity if required.

  • Green LED for power on indication
  • Red LED for gas presence indication
  • Amber LED for fault indication
  • Anti-shock casing material
  • IP54
