Operation Manual

NX-10 User Manual 37
EN50131 Mode is set by the installer. It changes the way a number of
standard system functions are performed in order to be compliant
with the EN50131 standard.
Keypad battery replacement
The user is allowed to replace backlight batteries only. Operating
batteries must be replaced by the installer. Therefore, the User Menu
option, Change Batteries, is not displayed in the EN50131 Mode.
Setting date and time
In the EN50131 Mode, the user is not allowed to set date and time.
This operation must be performed by the installer.
Screen saver
In the EN50131 Mode, the screen saver functionality is always active.
The screen saver turns on after 30 seconds of the user’s inactivity.
You can also turn it on manually by pressing both arrow keys
simultaneously. To cancel the screen saver you have to enter your
user code. When the screen saver is active, the alert keys (F1, F2, F8)
do not work.
Keypad keypress tamper
In the EN50131 Mode, invalid code entry attempts are limited to 5.
After 5 incorrect attempts the keypad gets disabled for 90 seconds.
During the Keypad Keypress Tamper all pressed keys are ignored.
This state is indicated on a display by the message "Keypad Locked".
Installer’s access rights in the EN50131 Mode
The installer is not allowed to access the system without the user’s
permission. Before the installer is able to enter the installer code, the
user must cancel the active screen saver by entering the user code.
Mandatory event log
In the EN50131 Mode, there are two logs: the regular event log and
the mandatory event log. The mandatory event log contains events
that are mandatory to register according to the EN50131 standard.
It can be previewed the same way as the regular log (see page 24). It
can be accessed with the User Menu>Mandatory Event Log menu
option.
Manual Dialer Test
This menu option is added to the User Menu in the EN50131 Mode. It
allows the user to manually test the dialer when the dialer fault is
signalled by the system.
