Product Description P/N: GD-6
Description
The Macurco GD-6 is a low-voltage, dual-relay combustible gas detector and ventilation controller for continuous monitoring of hazardous gas levels. It uses a microcomputer-based system with a pellistor sensor to detect methane, propane, or hydrogen, providing relays and 4–20 mA outputs for control and integration.

Information About GD-6
The GD-6 is a versatile combustible gas detector from Macurco, designed for industrial and commercial applications such as boiler rooms, warehouses, landfills, and battery charging stations. It can detect and display concentrations from 0–50% of the lower explosive limit (LEL), with relay outputs that can trigger exhaust fans, shut down supply lines, or activate alarms. The device mounts directly on a standard 4x4 electrical box, simplifying installation, and includes options for Modbus RS-485 and BACnet communication. With long-life sensors, configurable alarm levels, and ETL certifications, the GD-6 ensures both safety and compliance in demanding environments.
Key Features:
- Multi-Gas Detection: Selectable target gases include Methane (CH₄), Propane (C₃H₈), and Hydrogen (H₂).
- Dual Relays: Equipped with a 5A SPDT fan relay and a 0.5A alarm relay for control and notification.
- 4–20 mA Output: Provides continuous analog monitoring for integration with control systems.
- Configurable Settings: Selectable fan delay, alarm levels, latching modes, and buzzer operation.
- Fast Response: Sensor response time is less than 5 seconds for quick hazard detection.
- User-Friendly Interface: LED display, buzzer, and status indicators simplify testing and operation.
- Flexible Power Input: Operates from 12–24 VAC or 12–48 VDC, with optional Modbus or BACnet adapters.
- Certified Safety: ETL listed to UL 2075 and ULC 588, with CE compliance for international use.
The GD-6 delivers the accuracy and flexibility required for continuous combustible gas monitoring in industrial safety systems.
