Self-contained programmable terminal for security systems
First Claim
1. A security access system, comprising:
- a central processor, comprising;
a programmable memory storing data specifying personnel access at plural remote terminals; and
means for communicating with said plural remote terminals; and
plural remote terminals connected by said communicating means with said central processor, each comprising;
a programmable memory within said terminal storing data specifying personnel access for said remote terminal; and
means within said terminal for providing selective, programmable access at n remote location in response to either said central processor memory data or said remote terminal memory data.

Abstract
A security system is disclosed which utilizes plural remote terminals for controlling access at plural locations throughout a secured area or building. Each of these remote terminals is capable of independent functioning, and includes a memory for storing plural independent identification numbers which define the personnel who will be granted access. These numbers stored in the terminal memories may be different from terminal to terminal, or may be uniform throughout the system, and may be the same as a list stored at a central processing location. Thus, access may be limited to the same group of individuals regardless of whether it is provided by a central memory list or a remote memory list. The remote memories provide total memory flexibility, so that the deletion of identification numbers from the list does not reduce the memory size. The memory, in addition to identification numbers, stores data defining real time access limitations for each of the individuals who will be granted access, so that flexibility in time of day access control is provided on a programmable basis.
