A lift access control system is liable for all activities of an elevator. It controls everything from the floor determination buttons to weight sensors, and, obviously, lets the lift know where to go. There are three principal types of lift access control systems: single-programmed operation, particular collective operation, and group-programmed operation. Single-programmed activity systems are the most un-normal. They play out a solitary activity in light of an order and afterward hang tight for the following order.
Most lifts fall into the class of particular collective operation systems. With these sorts of lifts, calls to floors are replied in one direction. Then, the lift reverses to pick up in the other direction. At the point when the lift isn't being used, it is programmed to get back to the main floor.
group-programmed operation control systems are utilised in buildings with numerous lifts and a large number of floors. With these systems, microprocessors that can be modified are utilized for lift operations.
