The Macurco BRS-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.  This device simply connects to the back of the detector and a single screw fastens it in place. The BRS-485 accepts the 4-20mA output and is powered from the same connection as the detector. It can interface with Building Automation Systems, control panels, or other control devices that accept Modbus, BACnet, Metasys, and Siemens communication protocol.
