Brooks Firetracker FT128 CIE - Event Log; Loss of Main Power Source; Fault: Loss of Main Power Source; LCD Backlight

Technical / Programming Manual
FT128 Rev 2.2
123
 turn ON (enable) / OFF the Alert Annunciation function
 activate programmable control outputs
 turn ON (enable) / OFF (disable) the alternative alarm algorithm for analogue
detectors
One programmable input (trigger condition "External time channel") per time channel (N).
The input has to be connected to some external device, e.g. a key switch, a timer, etc. with
a normally open or a normally closed contact
134
. When the input is "activated" the time
channel (N) is ON.
Note: Do not use more than one input per time channel.
14.26 Event Log
The event log is divided into three types, i.e. Alarm, Interlocking and General.
500 events will be stored in each type of log. The logs are circular.
The event logs can be shown via menu H4/U6 (the latest event is shown "on top") or shown
/ printed via EBLWin or the Web-server.
Date & Time are stored together with every event.
14.27 Loss of Main Power Source
Regarding the Main power source and Second power source, see chapter “Power Supply”,
page 171.
14.27.1 Fault: Loss of main power source
This fault can be delayed since the CIE is powered via the backup battery in case of mains
failure, and mains failures are normally very short.
The delay time for the fault "Loss of main power source" can be set via EBLWin to 0-300
minutes (default is 30 minutes).
14.27.2 LCD Backlight
In order to reduce the current consumption, the LCD backlight is normally not turned on
during loss of the main power source. However in the Australian and New Zealand
conventions, the LCD backlight will be turned on also during loss of the main power source.
14.28 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 152
Zone groups function is introduced in EBLWin V2.2.0.
