Locking & Unlocking the Control Panel
The Precis SD Control Panel can be locked by pressing a sequence of Level Keys. Locking the panel
prohibits access to the system and can prevent accidental switching. The password can be any
combination of the first five Level Keys. The factory default password is the first five Level Keys, going
from left to right. The password can be changed using XNConnect (see page 51).
While the control panel is locked, BCS commands still work; however, they cannot be used to unlock the
panel. The panel remains locked if the power is cycled. If the password is lost while the system is locked,
contact technical support (see page 32).
After you press the Lock Key, you have 10 seconds to enter the password before the control panel reverts
to its previous mode (Locked or Switch mode). If you enter the wrong password, press the
Lock Key again and enter the correct password.
