It is a distinct internal component from the intercom’s main control or carrier board, display and power supply. Match the installed unit’s model, production revision and existing board before ordering. A door that fails to release can involve the lock circuit, wiring, access permissions or power as well as the door board, so this replacement should follow diagnosis of the complete entry-control path.\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\u003eCAPXM prior-to-2022 manual arrangement\u003c\/td\u003e\n\u003ctd\u003eManufacturer parts list identifies K001D8478; confirm the installed unit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAPXL\u003c\/td\u003e\n\u003ctd\u003eManufacturer service identification includes this family; verify its particular revision.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAPXLV or later CAPXM revisions\u003c\/td\u003e\n\u003ctd\u003eCheck the current model-specific service reference before assuming compatibility.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCAPXS \/ CAPXLV2\u003c\/td\u003e\n\u003ctd\u003eNo blanket fit established from the CAP name.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocks and readers\u003c\/td\u003e\n\u003ctd\u003eTheir power, wiring and interface requirements must remain compatible with the complete controller.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eDiagnose Entry Control Separately from Display or Network Faults\u003c\/h2\u003e\u003cp\u003eAn intercom can show a normal screen while a door fails to unlock, or an entry problem can originate outside the intercom entirely. Have the technician inspect the intended command, door-board connections, lock supply and field wiring before choosing a board. The repair should address the failed function rather than replacing unrelated electronics because they share the same enclosure.\u003c\/p\u003e\u003cp\u003eRecord the existing wiring and configuration before service, and preserve the site’s authorization and egress requirements.
