Built with a stainless steel housing, it provides a durable finish suited to high-traffic entry points. The unit features three metal push buttons for call or access functions and mounts directly to a flat surface, with conduit knockout holes at the top and bottom for clean wire routing. Licensed low-voltage technicians and security installers typically handle the wiring and commissioning of this type of unit.\u003c\/p\u003e\n\u003cp\u003eThe ace300hd is intended for residential apartment buildings and multi-unit dwellings where a surface mount installation is preferred over a flush or recessed approach. Its 4-wire configuration is compatible with standard intercom systems that use a dedicated 4-conductor run between the door station and the interior master unit. The surface mount form factor makes it adaptable to concrete block, metal door frames, or wood stud walls without requiring a rough-in box.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel housing for corrosion resistance and long-term durability in exterior or lobby applications\u003c\/li\u003e\n  \u003cli\u003eThree metal push buttons for call or entry-release functions\u003c\/li\u003e\n  \u003cli\u003e4-wire interface compatible with standard intercom wiring configurations\u003c\/li\u003e\n  \u003cli\u003eSurface mount design with top and bottom conduit knockout holes for flexible wire routing\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for both new construction and retrofit installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a surface mount door station for 4-wire intercom systems commonly used in residential apartment and multi-tenant building applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage or security systems technician in accordance with local codes and NEC Article 725 for Class 2 and Class 3 remote-control circuits.
