Abstract
An electronic control system (10) for use in controllably unlocking a locked drawer. Portions of the system (10) are located in the vicinity (12) of the locked drawer and portions are located in a remote location ( 11 ). The system (10) includes an operator accessible switch (14) located in the remote location (11), which switch enables two separate, parallel, redundant unlocking mechanism paths. Each path includes a time delay unit (17) that delays the opening of the locked drawer until a predetermined period of time following activation of the system by the operator, in order to allow time for the operator to move from the remote location to the locked drawer. In addition to providing power to circuitry that unlocks the locked drawer, the system also provides from the remote location, and then decodes at the locked drawer location, an authorization signal. Without this signal, the unlocking circuitry will not unlock the drawer, even in the presence of power.
