ABSTRACT:
A system is disclosed for sensing selected conditions particularly adjacent to an unoccupied commercial business building and taking the appropriate action. Corrective action may include shutting down a system, sending a signal to an occupied location for evaluation of the selected abnormal condition, or making a record of the abnormal condition for rectification at a later time. The system includes one or more light level sensors including microcomputer controlled photocell units directed to observe the light level at selected locations and to transmit signals indicating sensed light values below a desired value, and includes a receiver receiving the transmitted signals and which responds to such signals to produce a correction signal. If the commercial establishment is a bank and the light level is at an ATM (automatic teller machine) the system may respond to the correction signal by temporarily shutting the ATM machine down and illuminating a sign to indicate that the ATM is not open. If the condition sensed is a different type of discrepancy, failure of heating, water leak detection or other emergency, the system includes a modem and telephone communications link to a human monitoring station for instantaneous alerting and to allow corrective action.
