Zeta Alarm Systems.
The system toggles between events and the event summary about every 2.5 seconds. If more time
is needed to examine the events, you can press either the NEXT or PREV keys to enter a Quick-
Browse mode. Continue using the NEXT and PREV keys to page through the active events at your
leisure. Warning! Using the Quick-Browse mode will take you offline. Press Escape to go
back online.
When events occur, you also have the ability to view point labels for troubles that normally display
an event message by pressing "0". For example, a trouble might report "SLC Device Missing."
Pressing "0" might change the screen to say "Input Module," naming what kind of SLC device is
missing. This works whether the panel is online or offline. Note: this function is available online
only if key "0" has not been programmed as a Hot Key.
Pressing the SILENCE button will cause the piezo to silence and the Silenced LED to flash. This
occurs regardless of the number of troubles, alarms, and supervisory signals in the system (global
silence). When SILENCE is pressed and at least one new alarm or trouble exists in the system, the
Silenced message is sent to the printer and history file.
If the trouble clears (and troubles are configured as non-latching), either before or after Silence
Event, the Trouble Restore message is sent to the displays and printer. If all troubles clear and
there are no supervisory or fire conditions in the system, the system returns to normal operation
status, and the All Systems Normal message is sent to the LPD, ZRDA, history file, and printer.
This trouble restore occurs even if the troubles were never acknowledged (auto restore).
If multiple trouble conditions exist in the system, the LPD and ZRDAs on the system will step
through them automatically at three-second intervals.
Alarm operation is similar to Trouble operation, but with the following differences:
1. The piezo is pulsed -- 0.5 seconds on 0.5 seconds off
2. The System Alarm LED illuminates
3. The Display reports an Alarm event (AL) with the address, date, and time in the top two lines
4. The label of the point in Alarm is displayed in the third and fourth lines
5. Alarms latch and are not allowed to clear
6. Alarms cause recalculation of all control-by-event
7. Timers (Silence Inhibit, Auto Silence) are started
8. Alarms activate the general alarm relay, Group 99, and other Output Groups the input is
mapped to.
