The access control system will be a Corby Model 2016 "System 2" or approved equal.
System will control two doors. System will be housed in a metal cabinet measuring 15.5" x 11" x 4.5". Cabinet will have a hinged door with a lock to prevent unauthorized access to the wiring. Memory allocation for users, event storage and mode of operation will be adjustable. System will be programmable from a built-in keypad and 48 character LCD display. System will provide an RS-232 interface for optional programming through a video display terminal, PC or the connection of a printer. System will provide an RS-485, two wire interface for connection to other System 2's in a network. A maximum of eight systems will be networkable to provide control for 16 doors.
System will provide built-in charging for a lead acid battery to support full system operation upon loss of main AC power. System will contain a lithium battery for backup of user, system and event data upon loss of main AC power and main battery backup. System will support a perpetual clock and calendar system, accurate to the year 2086.
System will support 6000 users in two door, standalone mode and 4000 users in network mode. 16 time schedules will be provided for the control of users, doors and auxiliary functions. Each time schedule will consist of 64 cells each for a total of 1024 time cells. System will allow hard and soft antipassback. Auxiliary relay outputs will be triggerable from twenty different system events.
