The Alarm Lock PDL4500DB series locks are electronic digital proximity locks, which allow users access to restricted areas by either allowing them to enter a pin code at the lock's keypad, or by using a prox id card/prox keyfob. The locks support up to 2000 users who can gain access with either a pin or prox credential. 

Other features of the locks include automatic scheduling of up to 500 events, such as weekend locking schedule and holiday locking schedule. The locks also store 40,000 audit log of user door activities, which can then be retrieved for record keeping purposes.
