Destination Protect and Lock Functions
-
SSC3 provides two similar methods, Protect and Lock, by which a user can prevent or
control another user's ability to make switches on particular, defined destinations (output
signals) by assigning codes and priorities to control panels and control ports in the system.
Every remote control panel in the system is assigned a code number, called its Requestor
Code; and is also assigned a numerical Lock Priority value as part of the Panels
Configuration process.
A Protect function may be applied to a destination through any remote control panel with
lock/protect capability. Once protect is applied, the protected destination can not be
switched to a different source by any panel in the system, unless the panel attempting to
switch the protected output meets one of these three criteria:
-
-
-
A Lock function is very similar to protect, and may be applied to a destination through a
remote control panel with lock/protect capability. Once a lock is applied, the locked
destination can not be switched to a different source by any panel in the system, until the
lock is cleared by a panel with the authority to clear it, by meeting one of these criteria:
-
-
The key difference between protect and lock is that when a destination is protected, any
panel meeting the criteria to override the protect function operates totally impervious to the
protect function and may make switches on the destination just as it would to any other
unprotected destination. When a destination is locked, however, no panel may make a
switch on the destination until the lock has been cleared from the destination.
Requestor Code and Lock Priority Values
-
When panels are configured through Cattrax, each panel in the system is assigned a unique
address that identifies that panel, and only that panel, on the RCP bus. Each panel with
lock/protect capability is also assigned a requestor code value between 1 and 65535, and a
lock priority value between 0 and 1023.
Typically, and by default, the requestor code is assigned the same value as the panel
address. However, there may be certain circumstances of an installation that require an
exception to this numbering scheme. If you wish to allow two separate panels identical
control over a protected destination, you may assign the same requestor code and lock
priority to each panel.
Lock priority is a numerical value that determines the rights of a panel to place or remove a
lock or override a protect function on a destination. Panels with higher lock priority values
have greater control over lock/protect functions. Any panel assigned a lock priority of zero
(0) has the highest priority.
Proprietary Information of PESA
