ABSTRACT:
A security system for a goods-carrying compartment such as of a vehicle is arranged to indicate the sealed status of an access door40to the compartment. Following loading of the compartment, the system is used to seal the door closed by passing a security cable34through components46, 50of a lock mechanism associated with that door. The cable34is re-entered into the system housing30and then, using a key inserted into a security switch14,the system is activated to show proper sealing. An interrogation switch12may be pressed to illuminate LED22if the door40has not been opened following sealing or LED24if the door has been opened and not properly re-sealed with a key. Two different keys may be provided, one for use with the initial sealing of the compartment and the other for re-sealing by an authorized person such as a driver, so long as the compartment was opened for a legitimate purpose on route between dispatch and the ultimate destination.
