2 Installation & Connection
Gas detection and exhaust fan control is provided by a Macurco™ DVP-120 system. System wiring includes the main power
connection for the DVP-120, 4-20mA current loop and 24VDC power connections between the remote sensors and the DVP-120, the
fan control connections and/or alarm connections from the DVP-120 to the building ventilation and automation systems. The DVP-
120M also includes the RS-485 serial interface from the DVP-120M to the MRS-485 and remote detectors. Power to the MRS-485 and
detectors is provided by isolated/remote low voltage power supply.
The system configuration is entered by the user through the LCD display and keypad. The system display provides the user with the
system status, and the status of each configured sensor. In addition, all control functions of the DVP-120 may be accessed through the
system display and keypad.
