1 INTRODUCTION
1.1 General Information
The DVP-120 exhaust fan controller, in conjunction with 3M™ Macurco™ Gas Transducers, provides automatic controls to help maintain an acceptable environment in parking garages
or other facilities (see 3M.com/detection for information on compatible 3M™ Macurco™ Gas Transducers). The DVP-120 system is designed to meet specifications for safety in enclosed
parkinggarages,includingtheUniformBuildingCodeandOSHA50ppmCOrequirements.TheDVP-120cancontroluptotwelvegassensorsinanycombination(i.e.CO,NO2,EX).The
DVP-120 is ready for operation after the wiring is complete and the user system configuration is entered.
