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
Macurco Horn Strobe
The Macurco Horn and Strobe series is designed for spaces where distinctive visual or audible
signal is required.  These devices use low current to provide a high decibel output, and can be
easily seen and heard from afar.  The Horn and Strobe works well with Macurco products
including the DVP-120, DVP-120M control panels and the Macurco 6 & 12 Series detectors.  This
notification device can be flush or surface mounted on a double gang box.  

• Low Current Draw
• Operating Voltage: 16 to 33 VDC
• Audible Tone: Adjustable to Continuous (high/low) or Temporal Four (high/low)
• Strobe Candela: Adjustable at 15, 30, 75 or 110cd*  (
tested with clear lens cover)
• Strobe Flash Rate: One flash per second (20ms pulse duration)
• Multiple color options available: Clear, Red, Amber, Green and Blue
