GENERAL SAFETY INFORMATION
Intended Use
The Macurco MRS-485 adapter is an accessory used to convert the 4-20mA analog signal from Macurco 6-Series type detectors to
a digital signal for use with multipoint addressable systems. The Macurco MRS-485 simply plugs into the back of the detector and a
single screw fastens it in place. The MRS-485 accepts the 4-20mA output and is powered from the same connection as the
detector. The MRS-485 has the ability to interface with Building Automation Systems, Control Panels or other Control Devices that
accept Modbus communications.

USE INSTRUCTIONS AND LIMITATIONS
Each person using this equipment must read and understand the information in these User Instructions before use. Use of this
equipment by untrained or unqualified persons, or use that is not in accordance with these User Instructions, may adversely affect
product performance and result in sickness or death.
Use For
The Macurco MRS-485 Adapter converts the Macurco 6-Series 4-20mA analog output to a digital output for use with addressable
network systems. The Macurco 6-Series is a family of fully programmable, low voltage, dual relay gas detectors, controllers and
transducers for BAS, HVAC and Fire & Security applications. The 6-Series detectors are used to measure the concentration of
various gas and provide feedback and automatic control to help ensure a safe environment: Carbon Monoxide, Methane, Propane,
Hydrogen, Nitrogen Dioxide and other gases.
Do Not Use For
The MRS-485 is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants, etc. Do
not mount the MRS-485 where the normal ambient temperature is below 0°F or exceeds 125°F (-18°C or above 52°C). The MRS-
485 mounts to a Macurco 6-Series detector installed on a 4” x 4” electrical box electrical box supplied by the contractor.
