Event Flags
What are event flags?
Event flags are memory locations in a microprocessor system that register the
occurrence of certain events. Those events can be pre-defined or can be
programmed. In other words: when certain events take place, event flags are
triggered.
Why does the ATS system use event flags?
The ATS system uses event flags to provide the most flexible solution for
activating outputs and manipulating macros. Using event flags gives both options
using the same event flag. It is far more flexible then using fixed output types,
because fixed output types are hard to combine. Using event flags it is possible
to use the same event flag for more then 1 event, resulting in combined events.
What events can trigger event flags?
There is a multitude of events. They range from a zone being activated to a 230
V mains failure, from users opening doors to entry/exit timers running. In total
event flags can be programmed in:
• Zone database as “Zone event flag”. Zones can also be linked to pre-defined
event flags for siren events, armed or disarmed alarm flags and more. Event
flags are triggered when certain events occur regarding this particular zone.
• Area database. Here are event flags triggered for entry or exit timers, sirens
being activated, alarms occurring etc. Event flag are triggered when certain
events in an area occur, regardless off the zone.
• RAS database. When using door commands, a door can be opened.
• Zone Shunt. When a zone is shunted due to opening of a door.
• Summary event flags contain system events like 230 V mains failures or low
battery.
• Macro Logic uses event flags or an output status to manipulate zones or
event flags.
• The 4-door DGP and 4-lift DGP can trigger event flags internally. See the
programming manual for the appropriate DGP.
Some events trigger event flags in different sections. When a zone goes into
alarm:
• The siren is activated (programmed in the area database and the zone
database)
• Also an indicator above the door might be lit, because the zone event flag is
also triggered.
All this happens at the same time, activated by the same event: the zone causing
an alarm.
