  • Page 4: Safety And Information

    National Standards, Electrical Codes and all local ordinances. • Never operate the GDMP without a connection to Earth ground. Failure to connect the device to Earth ground can result in electrical shock. Electrical shock can cause damage to the GDMP and injury to personnel.

  • Page 5: Maintenance

    Verify proper system operation by performing a full, functional test of all component devices of the safety system, ensuring that the proper levels of alarm occur. Check the calibration of the sensor(s) connected to the input(s) of the GDMP according to the recommended schedule in the device manual(s).

  • Page 6: Introduction

    2. Introduction 2.1. Product Description GDMP is a gas detection monitoring panel that allows control and monitoring of multiple gas detectors from a single point. The monitoring panel can be used to control flammable/explosive or toxic gas detectors with industry standard 4-20 mA analog output and flame detectors with digital inputs.

  • Page 14: Wiring

    3.2.2. Wiring Gas detectors with 4-20 mA output can be monitored with GDMP control panel. The V+ and GND detector connections on the analog inputs provide 24VDC to the detector. mA connection reads the detector output (4-20 mA). As the distance between the detector and the control panel increases, the detector supply voltage will become weaker, so cable diameters should be determined according to the distance.
