Additional Features
The Macurco 6 & 12 Series fixed gas detectors provide life-saving solutions to protect people and property. These fixed gas detectors are designed for low-level detection, mitigation and notification. Let these detectors do the work for you by shutting off valves, turning on fans, engaging horns and strobes and providing notification to fire panels and building automation systems when gases reach vital limits.
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.
