Abstract
An electronic security system for a parking meter includes a vault door having a spring-biased contact terminal for making breakable electrical contact with a housing hinge bracket contact terminal mounted in a vault opening. An electronic lock control circuit is able to communicate with a meter control (coin counting/auditing) circuit in the meter portion of the system through the vault door/housing hinge bracket contact terminals, thus eliminating a direct cable connection between the lock circuit and the meter circuit. The spring-biased contact may be substituted by equivalent breakable electrical contacts such as optocoupler contacts.
