Access Levels
The control panel provides protection from unauthorized access of certain functions by
various access levels.
The TSA-1000 includes electronic and mechanical mechanisms that enact 4 access
levels, as per EN 54-02 Annex A:
•
Access level 1 – not limited, immediate access by operator
•
Access level 2 (operator) – protected by an operator password. Provides all of
access level 1 functions and allows access to additional functions that are
performed on a regular basis by the system’s operator.
i
Note
To avoid multiple PW key punching, there is a 3 minutes period after the
operator's PW has been entered, when the PW remains valid and effective,
which enables the operator to perform several tasks continuously without
entering the PW separately for each action.
(Since. In the password delay, the reentering of level 2 PW is not required,
level 2 access appears to be level 1 access, and level 3 appears to be level 2
access)
Access level 3 (programmer & installer) – protected by a programmer
password (different from the operator's password!)or a mechanical key.
Provides all of access to level 1 and 2 functions and allows access to
additional functions such as programming, and access for functions
performed during installation.
i
Note
Access levels 2 and 3 have different passwords. This is not correlated to the
number of times the password has to be keyed in to access a certain menu.
Some sub-menus which are accessible at level 3, require that the level 3
(programmer) password be entered in a single menu, while others (for
additional safety) require the level 3 password to be entered in to different
menus
•
Access level 4 (manufacturer) – Only accessible using a dedicated PC SW tool or a
mechanical key.
The mechanically controlled access elements are detailed below.
The ECD enclosure has a door/front-panel with a mechanical lock. A detachable key is
required to open the lock, which requires a positive and deliberate action and prevents
accidental and non authorized access. Hence the access level to the batteries and AC
power lines and the field wiring connections is 3/4.
Two switches are located on the front panel. A Manual &Automatic/Manual Only key-
switch and a Manual Activation Push Button switch.
