A button connected only to a BAC input does not satisfy this requirement.  We often suggest egress buttons from Seco-Larm for this purpose.\u003c\/p\u003e\n\u003cp\u003eUse locking hardware that releases on loss of lock power, and provide any required fire-alarm and emergency-system releases independently of the BAC. The installer and operator are responsible for ensuring the complete installation complies with applicable building, fire, accessibility and egress requirements, including any approvals required by the local authority having jurisdiction. Installing a BAC or an override button alone does not establish compliance.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003ch2\u003eManuals and downloads\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.escaperoomtechs.com\/wp-content\/uploads\/2022\/05\/BAC-Getting-Started-Guide.pdf\"\u003eGetting started guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.escaperoomtechs.com\/manuals\/bac\/\"\u003eBAC and BAM manual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.escaperoomtechs.com\/downloads\/\"\u003eBAM downloads and available firmware builds\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"bac-contact\"\u003e\n\u003ch2 id=\"bac-contact-heading\"\u003eLet’s talk about your build\u003c\/h2\u003e\n\u003cp\u003eWhether you are planning your first puzzle, adding a prop to an existing room or working through a wiring problem, we welcome the conversation.
