The AD-300 is a wired electronic lock designed to be modular and provide more. More options to choose from, more built-in functionality, more credential options, and more compatibility with access control systems. Its patented modular design allows the lock to be customized to fit the needs of an application now and can adapt to meet future technology needs without removing it from the door. The open architecture design allows it to be integrated into over 40 leading physical access control systems through our PACS Alliance program. This enables customers to choose the system that best fits their requirements. AD-300 locks securely communicate either directly to an access control panel via RS-485 or, in a Wiegand or Clock and Data system, through a panel interface board (PIB). Available as cylindrical, mortise, mortise deadbolt or exit trim, the AD Series features built-in access control sensors and is compatible with a wide range of credential technologies. The AD-300 can work in the same system as other Schlage wired and wireless access control devices to meet the requirements of any application.
