The DKS 2348 Elevator Control System provides complete elevator security that is typically used in high-rise condominium, apartment, or office building applications. The system will restrict which floor a visitor has access to via the elevator after they have been granted access by a building resident and is programmable to restrict building residents to certain floors or grant them access to all floors. Residents must use their access card (or other access control device) to "turn on" the floor buttons that they have access to. Each elevator board can control up to 16 floors, with a maximum of four (4) elevator control boards interfaced with a single elevator for a total of 64 floors. Each access controller can control up to eight (8) elevators in this manner. Includes mounting hardware.
