Testing

The Macurco MRS-485 adapter converts the 4-20mA analog signal from Macurco 6-Series type detectors to a
digital signal for use with multipoint addressable systems. The 6-Series test procedures may be used to ensure
that the MRS-485 accepts the 4-20mA output for the Modbus communications. All 6-Series detectors are factory
calibrated and 100% tested for proper operation. The units also perform a regular automatic self-test during
normal operation. If the unit detects an improper voltage or inoperable component, it will default into Error
REV – 1.0
