The event memory can be accessed by using the menu point [Event memory]. You can set one of the
possible filters [Display all], [Control panel] or [Detector zones] for the displaying of the events by the
use of the '
↑↓
'-buttons. After confirming the chosen filter with the '
↵
'-button, the most recent event is
displayed with its running number. Now you can scroll forward or backward in the event memory by
using the '
↑↓
'-buttons. The event with the number *001 is always the oldest event kept in the event
memory.
An overview of all possible event texts can be found starting page 68 in Chapter 7: "Event memory -
entries".
An example for the display of an alarm:
ALARM 0001/016

Figure 14: Display of the event memory entry (here, Nr. 234) of an alarm of the detector zone 1, detector Nr. 16.
Has no element text been programmed, the second zone text (if available) is displayed.
To gain space for the running number, the information displayed in the third line (here, the element
text) is shortened to 16 characters for displaying.
By pressing the 'Info'-button, date and time of occurrence of the event and - depending on the kind of
event - extended event texts as well as the GSSnet member number are displayed on the LC-display.
4.7.12 Menu point [System]
In this menu point you can get a read-out and modify settings of different system information, as de-
scribed in the following.
With the fire detection control panel BCnet216 all menus related to date and time can be called on the
BCnet sectional control panel defined as main operating unit only. All clocks of other BCnet sectional
control panels are permanently synchronized with the time of this BCnet sectional control panel.
4.7.12.1 Read-out of the event counter - submenu point [Event counter]
You can display the number of alarms that have triggered an activation of a primary transmitting device
or a transmitting device for fire alarms since the fire detection control panel BC216-1 or all BCnet sec-
tional control panels of a fire detection control panel BCnet216 were first put into operation. If the cor-
responding transmitting device is already activated, no further alarms are counted.
BCnet sectional control panels which were limited to a part of the whole fire detection system by an
area filter during commissioning will only count alarms which originated from that part.
The event counter (alarm counter) cannot be reset.
4.7.12.2 Testing the optic and acoustic displays and the buzzer - submenu point [Display test]
In this test, the buzzer, the LC-display and all light-emitting diodes are activated. Thereby you can
check easily if all displaying elements work. The same functions are executed by pressing the button
'Silence buzzer'. (See from page 25 in Chapter 3.6: "Reset-buttons").
4.7.12.3 Setting the contrast - submenu point [LCD contrast]
Using the '
↑↓
'-buttons you can set the contrast of the LC-display in 10 steps, according to the position-
ing of the control panel (viewing angle) and to local light conditions. Minimum requirement for this
submenu point is authorization level 2.
