Macurco 4S1D-1-RB  Macro 120VAC Alarm/Relay 4X4  MNT REPLACES 4S1D1BR 3M Macurco GT-11A Combustible Fixed Sensor Transducer, GT11A, %LEL, 12-24V, 4-20mA, ETL Approved

Combustible solid state sensor analog transducer GT-11A offers dual linear output transducer, 4-20ma output, and 24 VAC or VDC operation. GT-11A is for use with the DVP-120 or with HVAC/Building Automation Systems. The GT-11A is a dual linear output transducer for use with Building Automation Systems, Energy Management Systems, Macurco DVP-12 Control Panel. Unit sends either a 4 to 20 milliamps or 1 to 5 volt signal.

  • The standard calibration for the GT-11A is to the following range: 0 to 10,000 parts per million (ppm) of methane. 10,000 ppm is approximately 20% of the Lower Explosive Limit (LEL) of methane.
  • Easy installation: Input voltage is 24 VAC or 24 VDC. The unit mounts over a standard 4 x 4 electrical box. Optional duct mounting kit (DMK-1) is available for special applications.
  • Dual operating LED indicators: the green LED indicates normal operating condition, while the amber LED indicated a trouble condition.
  • Supervised System: Unit continually performs an internal self-test. The amber LED indicates a trouble condition if there is a sensor or circuit failure.
  • Standard calibration detects the following gases: methane, natural gas, propane, butane, gasoline fumes, acetylene and LP.
  • Special calibrations are available to detect other hydrocarbon gases including: jet fuel, alcohol, ethane, kerosene, xylene, etc.
  • Low maintenance self-purging semiconductor sensor. Sensor life is 7 to 10 years.

  • Macurco (Aerionics) GD-2B Combustible Gas Detector - MA-GD2B Macurco 3M GD-2A GAS DETECTOR FLUSH 12/ 24V - MA-GD2A
    Macurco Combustible Gas Detector GD-2B For use with alarm control panels for Methane and Propane Gas Detection

    The GD-2B is a low voltage electronic detector of combustible, heating type gases. The GD-2B is designed for connection to Fire Alarm/Burglary Control Panels. The GD-2B is intended for installation in buildings in non-hazardous locations such as residences, retail stores, office buildings, and institutional buildings. This combustible gas detector has been calibrated for detection of methane (natural gas) and propane (LP) gas. It is NOT designed to detect smoke, fire or carbon monoxide.

    The GD-2A is an all electronic detector of heating type gases (natural and bottle), designed for use alone or for connection to alarm control panels. It can operate on 12 to 24 VDC power from standby or interruptible panel power, or be powered separately.
    The attractive two part plastic case allows the GD-2A to be installed over a four inch square or double gang electrical box, providing a near flush mount. Six inch long pigtail leads are provided for connections to the control panel or other devices.
