Key Management System

The new SmartKey+ key management system from Smith Flow Control (SFC) provides additional security for managing safety interlock keys. The SmartKey+ provides infallible protection against unauthorized or inadvertent operation of interlocked valves or process equipment, with the added ability to record movements of the keys required to operate mechanical interlocks in real time.SmartKey+ traps all keys in the cabinet until authorization is granted. To access the key cabinet, users must identify themselves with a PIN code. 

SmartKey+ highlights specific key positions that the operator is authorized to use. The user then selects the appropriate key from the panel and removes the key as the selected key position is unlocked. To return a key to the cabinet, the user scans the key with the integrated scanner and the corresponding key position is highlighted on the front display for re-insertion.SmartKey+ uses RFID technology to report the recent actions and current status of interlock keys with complete accuracy. Full transaction history is available, revealing details of key insertion/ removal. The unit is designed to support a remote web interface, without any specific license. The SmartKey+ is configured around a central control panel capable of managing over 275 keys. The system is made of modular sections, each containing 18 key positions, and can be increased incrementally.
