Abstract
A system for monitoring the tour that a guard must undertake in each building of a large number of building sites involves an arrangement in which a system control center has a two-way communication by telephone network with each of a large number of building sites. Within each building, a building site unit has a two-way communication by broadcast with a large number of tour station units. A guard with a guard identification card checks in through a card reader at each tour station unit. A unique tour station unit identification number is associated with the guard identification number and transmitted to the building site unit where it is associated with a time and date and transmitted to the system control center. In this fashion, a large number of sites and a larger number of tour station units can all be monitored on close to a real time basis. A defective tour station unit can readily be replaced with a standard unit available at each building site. Under control of data transmitted from the system control center. A PROM at the tour station unit can be programmed to provide the appropriate tour station unit code number.
