Lock Modes
A lock is shipped from the factory with default lock “setup” values and a pre-set PIN
for unlocking the lock. This is referred to as Factory Mode.
The lock is shipped with a default factory Super Master User PIN that can be set
(i.e., changed) when the lock is in Factory Mode. Once the Super Master User PIN is
set, the Super Master User combination can be used to shelve the lock in the event
that the Master User combination is lost. Refer to the
Super Master Operations
(Document # 3072.026) for more detail.
WARNING:
The setting of the Super Master User PIN is optional, however, if you do
not set the Super Master User PIN before setting the
Master User PIN, all
Super Master User capabilities will be permanently lost.
The lock is removed from Factory Mode when the Master User PIN gets changed.
The lock has two modes of operation: Independent Mode and Supervisory/
Subordinate Mode. Within each operation mode, two access modes are available:
Single User access and Dual User access. In Single User access, only one
combination is required to open the lock. In Dual User access, two combinations
must be correctly and consecutively entered to open the lock.
• Independent Mode - When operating in Independent Mode, the Master User can add
Access Users. One (Single User access) or two (Dual User access) combinations are
required to open the lock.
This is the default operation mode for the lock when the
Master User PIN first gets changed.
• Supervisory/Subordinate Mode (Super/Sub Mode) - When operating in Super/Sub
Mode, the
Master User can add Supervisors. Subordinate Users must then be added by
and assigned to a Supervisor.
In Single User access, one valid User combination is required to open the lock.
In Dual User access, two valid User combinations are required to open the lock.
If a Supervisor disables lock access for the Subordinate User(s) assigned to a Supervi-
sor ID, the Subordinate User combinations for that Supervisor ID will no longer be valid
combinations for lock access.
To remove a lock from an operational mode, one can “shelve” the lock which places
it in Shelved Mode. Most lock values are returned to the factory default.
Personnel Classifications
There are four different classifications of lock personnel:
• Master User - The Master User performs the initial lock setup activities and can also
shelve the lock. There is a maximum of one
Master User per lock. The Master User
combination will also open the lock.
• Access User - In Independent mode, a user added by the Master User. An Access User
can open the lock.
