When the LED is GREEN with random bursts of AMBER, the operation is normal, and data are being received or transmitted over
the RS-485 line. The AMBER LED will come on anytime that there is data traffic.
NOTE : After complete system installation, verify all sensors (verify sensor address and sensor type) connected to the panel are
detected by the panel and there is not any trouble indication for any of the connected detector.
3.2.4.2 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 circuit definition with selectable 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.

3.2.4.3 Dip Switches and Addressing
Each MRS-485 (and the detector it’s connected to) must be configured to a unique address. If there are 10 detectors on the
serial line, then 10 unique addresses must be used, one for each detector. To set the address, use the eight DIP switch positions.
For each unit choose the value from 1 to 192 (see chart) and set the eight switches to match the address. UP means ON or 1 and
DOWN means OFF or 0. For example, to configure a unit as address “50”, set switches “2, 5, 6” (see Table 3-3) to ON or in the up
position (01001100).
NOTE: If CX-6 is assigned address X and connected to DVP-1200, then address X is assigned to NO2 Sensor (Type: 2) and address
X+1 is assigned to CO Sensor (Type: 1) by the panel.
