Real time clock (RTC)

Each Control Unit has a built-in RTC. It is used for date and time presentation in conjunction
with fire alarms, faults, event logging and the time channels 2-14. In a system with two or
more Control Units in a TLON network, the time in all Control Units will be synchronised.
The RTC does not have a backup battery, i.e. the date, time, etc. has to be set (via menu
H3) after loss of the power supply (no mains and no battery backup) and after software
download.

Daylight saving time

The time is automatically changed when the Daylight saving time period starts and stops
respectively, if set so in EBLWin (system properties / page 2). The daylight saving time will
be automatically changed in the AU and NZ conventions as follow:

Australian convention: Forward 1 hour the first Sunday in October, 02:00  03:00.
Backward 1 hour the first Sunday in April, 03:00  02:00.

New Zealand convention: Forward 1 hour the last Sunday in September, 02:00 
03:00. Backward 1 hour the first Sunday in April, 03:00  02:00.

Fault: Loss of main power source

The delay time for the fault "Loss of main power source" can be set in EBLWin to 0–300
minutes. Default setting is 30 minutes.
17.27.2

LCD backlight

In order to reduce the current consumption, the LCD backlight will be turned off during loss
of the main power source.

Zone Groups

Zones can be grouped together in a zone group. The zone group is given a name e.g.
"Level 2" and then can be used in control expressions to activate outputs e.g.
FireAlarmZoneGroup ("Level").
Maximum 30 zone groups can be defined. Each zone group can contain unlimited number
of zones but a zone can only be a member of one zone group.
See also chapter "Zone groups" page 158
Zone group function is introduced in EBLWin V2.2.0.

The calendar and clock can be set in any C.I.E. for the whole system. Every day (at midnight) all calendars and clocks will be
synchronised.
