MRS-485 Adapter
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 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.

• The MRS-485 monitors sensor type, gas level and trouble status communications
• Communication is on a Modbus serial line
• Commercial type enclosure to protect and support the electronics
• Tricolor LED indicates power, test and communication status
• Mounts behind the detector inside of a standard 4” x 4” electrical box
• 8 bit dip switch address selector
