GE Security Alliance AL-1256 4-Door Controller DGP & Enclosure Access Control

Grade A Condition. Comes as seen in pics. Pulled off working install. 

The AL-1256 intelligent 4-door controller data gathering panel (DGP) extends the Alliance system's access control and security functions. Allowing up to four readers/keypads per door, it adds intelligence to those doors while accommodating four total door openings. The AL-1256 monitors the status of the doors (open or closed) and the status of the door locks (locked or unlocked), as well as handles forced door and door open too long (DOTL) events, with variable shunting times for physically challenged users. The intelligent 4-door controller enables PIN-plus card badging for high security applications, allows two doors to be interlocked, and accepts privileged cards to override antipassback and disabled readers.
