4— Service Mode Operation
Service mode operations require the input of a Service User’s four-digit PIN code, an eight- digit operation code, and presentation
of a valid Service touch key. The presentation of the PIN, operation code, and the touch key must be made to the lock during the date
and time window specified by the system operator when the operation code was generated. This operation is setup using the Lock
management system (LMS).
4.1 Service Mode Operation Process
The process below can be utilized by User (black keys) or Managers (red key) code:
1) User places their touch key in reader.
2) User inputs their four-digit PIN and presses the # key.
3) User inputs the eight-digit operation code and presses the # key.
4) Lock illuminates Amber “Mode” indicator during processing of code.
5) If the operation is verified and allowed by the lock, the response will be three Green “Status 1” indicator flashes along with
three beeps. If the request is denied, the Red “Status 2” indicator will be used in conjunction with a beep pattern to indicate
code failure. Reference Beep Patterns to identify the failure condition.
6) User removes touch key.
4.2— Service Mode Operation Codes
Service Mode operation codes may only be generated by the Lock Management System for locks that have been previously
initialized. The operation codes are eight digits in length and will be valid for only one use. If the operation code is not used, the
code will expire at the end of the time window specified by the operator of the Lock Management System at the time the code was
generated.
Each operation code is specific to the lock being addressed, the user, his four-digit PIN code, the touch key being presented, the
request being made, and the date and time the code is valid.
