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 alarm connections from the DVP-120 to the
building ventilation and automation systems. All power and signal connections for the sensors are provided from
the DVP-120 control panel, via unshielded four conductor cable. The DVP-120 control panel provides three
relays which can be used for ventilation fan control or alarm signaling. The ventilation control function operates
independently from the alarm function. It provides the ability to configure the DVP-120 for control of one to three
zones. Each zone can respond to gas levels at one or more of the sensors, with configurable rising and falling
concentrations for each gas type. Each zone can also be controlled based on the time of day.
