Notethat no other user type can read the log.Mandatory and Non-Mandatory Log EventsTo comply with EN50131-1:2006 for Grade 2 and 3 systems the log is divided internallyinto two portions: mandatory events and non-mandatory events. The installer can vieweither of these lists separately, or see all log events in one list. To assist with this task theInstaller Menu – View Log option provides three choices: All Events, Mandatory Eventsor Non-Mand Events.The number of events each area of the log can store is given on page 9.The entire log will store its records for at least 10 years without power.How the Log Displays User IdentitiesWhen you view the log, the display initially shows users by their number (for exampleUser001). Pressing displays any name programmed for the user.There are some user numbers that have special meaning, see the table below. Note thatthese user numbers depend on the type of control unit.Special User Numbers Control unit typeUser Identity i-on16 i-on30 i-on40 i-on50 i-on160Installer (see Note). 00 000 00 000 000Quick Set User 17 051 51 101 501Panel (Control Unit) 18 052 52 102 502Keyswitch User 19 053 53 103 503ARC Remote Reset 20 054 54 104 504Downloader N/A 055 55 105 505Virtual keypad N/A 056 56 106 506Note: The word “Web” will appear in the log entry if the installer logged on using the webbrowser.
