Keypad keypress tamper
EN 50131 requires detection of repeated invalid authorisation attempts done with logical keys.
During code entering every entered digit is indicated by a number (1, 2, 3, etc.) in the right lower
corner of a display. A valid code must be entered within 60 seconds from the first keypress,
otherwise it is treated as invalid.
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 information "Keypad
Locked". If the Keypad Keypress Tamper occured then the Keypress Tamper event is logged with the
partition number and the keypad ID.
The multipartition keypad also gets locked after 5 incorrect attempts. The multipartition keypad with
the Partition Keypress Tamper received from the control panel allows to operate on not locked
partitions. If not all partitions are locked, locked partitions are indicated on a multipartition keypad
by exclamation marks "!". If the Keypad Keypress Tamper occured at the particular multipartition
keypad or all keypad partitions are locked then "Keypad Locked" message is displayed and the whole
keypad is disabled.
Incomplete Exit
If during arming, the Entry/Exit zone (for example, an exit door) is open at the end of the exit time
then the system will not be armed and the special SIA code EE will be reported. Each Exit Error
event is visible as a fault to acknowledge and it should be acknowledged.
Keypad volume turned down
If the keypad volume is set to 0 then in case of a reject beep (silenced) "Err" will be displayed for 1
second instead of digit icons. It allows the user/installer to notice that the setting was rejested by the
system and the attempted change was unsuccessful.
Menu
Some menu options differ when the system is in the EN 50131 mode.
Set Date/Time
When in the EN 50131 mode the Set Date/Time menu option is displayed under Installer
Menu>Maintenance Mode. When the EN mode is disabled, this menu option is available in the User
menu.
EN Mode
This menu is visible in the EN mode only, and can be used for switching this mode off. It is
available at Control Panel>System Settings>Feature Select>Miscellaneous>EN Mode.
Please note, that switching the EN 50131 Mode off does not change back any options set by
switching this mode on previously. They must be set up manually as needed.
