It provides a manual momentary contact output that signals an electric strike, magnetic lock, or access control panel to release a secured door. The CM-850 mounts directly to a wall or door frame surface without requiring a back box, making it a practical choice for retrofit installations and new construction alike. Licensed electricians and low-voltage access control technicians are the typical installers of this device.\u003c\/p\u003e\u003cp\u003eThe CM-850 is suited for interior pedestrian door applications in both residential and light commercial settings. It is commonly installed at exit points where a push-to-exit function is required — allowing occupants to egress without a credential. Typical locations include office corridors, apartment building entries, medical facilities, and institutional doorways where controlled egress is part of the overall access control design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSurface-mount form factor eliminates the need for a wall box, simplifying installation\u003c\/li\u003e\n\u003cli\u003ePush button actuator provides momentary contact output for door release signal\u003c\/li\u003e\n\u003cli\u003eCompact design fits standard egress and access control wiring configurations\u003c\/li\u003e\n\u003cli\u003eSuitable for use with electric strikes, magnetic locks, and access control panels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style surface-mount push button for use with access control systems that accept a momentary contact door release input, including electric strikes and electromagnetic lock controllers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or certified low-voltage access control technician.
