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 multi-point 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.

Product Features

  • The Macurco MRS-485 interfaces the detector power and 4-20mA output lines with a mounted connector
  • The MRS-485 monitors sensor type, gas level and trouble status communications from any of the Macurco 6-Series detectors
  • Communication is on a Modbus serial line
  • Commercial type enclosure to protect and support the electronics
  • Tricolor LED indicates power, test and communication status

Installation

  • Mounts behind the detector inside of a standard 4" x 4" electrical box
  • Held in place on the back of the 6-Series detector with a single screw
  • 8 bit dip switch address selector
  • RS-485 termination uses 4 pin connector with jumper to select termination: The user selects no termination or one of the two Modbus line termination options
  • Communications connections include signal (A and B), common and shield terminals
  • Intended for use in non-hazardous areas such as parking garages, warehouses or other commercial facilities

Gas Detection

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.

Connection

The Macurco MRS-485 output is connected via a four terminal screw type connector. The MRS-485 adapter is wired in the standard 2W-Modbus circuits definition with select-able built-in terminating resistors at the ends of the RS-485 bus. The power for the MRS-485 adapter is connected via a two terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity. Note: Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.
