Abstract
A multi-unit monitoring system includes a plurality of units coupled to a communication medium. The system can also incorporate a common control element coupled to the medium. The individual units include control circuitry which is capable of carrying out verification, confirmation, or entry/exit delay processing. While the control element can receive messages from the various units indicative of their status, the units themselves carry out the respective timing functions.
