ABSTRACT:
An electronically controlled locking system for use with coin telephones. The system is preferably utilized in conjunction with and controlled by the Wesroc.RTM. Coin Phone Monitoring System. Existing coin phone lock mechanisms consist of a primary lock and a secondary lock. The primary lock actually physically secures the coin vault door in position. The secondary lock locks the primary lock in a locked position. Both locks are mechanical systems which are actuated by mechanical key devices of a common type and structure. This mechanical system is prone to fraud and theft. The present invention provides an electronically controlled latching mechanism for controlling the operation of the existing locking mechanisms.
