3.4 Sleep Mode
VP-II X enters into a sleep mode when there is no User activity for the set period if enabled (factory
default). It is not only to minimize power consumption but also to maximize the life time of the system.
Keypad LEDs and LCD backlight will be minimized in sleep mode, and return to normal when a User is
detected by the IR sensor of VP-II X.
3.5 Tamper Switch Setting
A tamper switch is installed on the rear cover. VP-II X detects the switch when it is detached from the
wall bracket without authorization. If enabled, VP-II X generates a warning sound and sends an event to
the server when it detects the tamper switch has opened. It is recommended that you disable this
function when taking the VP-II X off the wall for maintenance purpose.
3.6 DB Search Option
A Manager can set the sequence of database searches – local, network or both. The default is to firstly
search the User data from the local database, and secondly from the network (Master’s database) if it
failed to retrieve the data form the local database for any reason. If necessary according to the network
environment, it may be changed accordingly.
This option is available for only slave units. The master unit always refers to its own database.
