Macurco 70-2900-0012-1 MRS-485 RS-485 Adapter

Product Description

The MACURCO 70-2900-0012-1 is an RS-485 communication adapter designed to integrate compatible Macurco gas detectors into RS-485 network systems. The adapter extends the communication capability of supported detectors, allowing them to transmit sensor data over a wired serial bus to building automation systems, controllers, or monitoring equipment. Licensed electricians and fire or gas detection technicians typically handle installation. It is sold as a single unit and is categorized as a detection accessory.

This adapter is used in commercial and light industrial environments where gas detection devices must communicate over an RS-485 serial network. Typical applications include multi-zone gas monitoring systems tied to building management or ventilation control systems. It provides a standardized interface between the detector and downstream control infrastructure, reducing the need for custom wiring solutions between incompatible communication protocols.

Key Features

• Enables RS-485 serial communication for compatible Macurco gas detectors
• Extends detector integration into building automation and monitoring networks
• Sold as a single unit for targeted replacement or new installation
• Classified as a detection accessory for gas detection system infrastructure

Compatibility

Designed for use with compatible Macurco gas detectors that support RS-485 communication. No specific detector model numbers were provided in the product data. Consult the Macurco product manual for a complete list of supported detectors before installation.

Installation Notes

Installation should be performed by a licensed electrician or a qualified gas detection system technician. Power down the detector and any associated control panel before connecting or disconnecting the adapter. RS-485 wiring should follow NEC guidelines for low-voltage signal wiring, including proper shielding and termination to prevent signal degradation. Do not apply line voltage to the RS-485 communication terminals.
