It provides separate Open, Close and Stop controls, and the MAXUM accessory documentation identifies its enclosure classification as NEMA 4\/4X\/12. Select it with the operator’s supported control wiring and operating mode in mind. An outdoor enclosure does not make the station suitable for every hazardous environment, and installing a three-button station does not automatically authorize unattended or momentary closing at the door.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported MAXUM commercial operators\u003c\/td\u003e\n\u003ctd\u003eListed as an outdoor control accessory; follow the exact operator wiring instructions.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther commercial door operators\u003c\/td\u003e\n\u003ctd\u003eVerify approved control type, terminal arrangement and circuit requirements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResidential digital wall-control terminals\u003c\/td\u003e\n\u003ctd\u003eNo direct compatibility established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHazardous or explosive atmospheres\u003c\/td\u003e\n\u003ctd\u003eNEMA 4X is not an explosion-proof or hazardous-location approval.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMomentary closing operation\u003c\/td\u003e\n\u003ctd\u003eRequires the protection devices and operating mode specified for the complete door system.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eMatch the Station to the Door’s Control Circuit\u003c\/h2\u003e\u003cp\u003eThe three buttons provide distinct commands, but the operator determines how those commands are used.
