Macurco DVP-120 Multigas Detection and Ventilation Control Panel
Description
DVP-120 Multigas Detection and Ventilation Control Panel. Up to 12 analog sensor inputs, three 12amp output relays, Nema 1 enclosure, Digital display shows sensor and system status. Meets OSHA & UBC standards.
General Information
The DVP-120 Gas Detection and Ventilation Control Panel is a microcomputer based control panel used to operate ventilation fans based on the inputs from remotely mounted gas transducers. The unit is fully tested prior to leaving the factory, and is ready for operation after the wiring is complete and the user system configuration is entered. System wiring includes the main power connection for the DVP-120, current loop and 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. Refer to Figure 1-1 for a representative system-wiring diagram. The system configuration is entered by the user through the LCD display and keypad. Refer to Figure 1-2 for equipment locations. 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.
