10.5 Event Priority

This section goes over how event activations are handled by the control panel with regards to priority.
10.5.1 System Control
The 6820 or 6820EVS control panel integrates both a fire and emergency system into one. When events are active from both systems the
control panel makes intelligent decisions to determine which system should be controlling outputs. This is called System Control. This
manual will refer to the fire or emergency systems having System Control, this means that the system has an active alarm or supervisory
event that has a higher event priority than an active alarm or supervisory event from the other system. For this consideration, the control
panel looks at the highest priority event active on each system. When both systems are active, the system with control will activate Sys-
tem Override. System Override is activated on the lower priority, non-System Control panel system (fire or emergency system.)
10.5.2 System Override
System Override temporarily disengages output group activations from the system being overridden. This is done to not provide conflict-
ing messages and signaling and help with reducing confusion of the building occupants.
When output groups are supposed to be active but are not because System Control has activated System Override, they are re-activated
every 30 seconds for 2-3 seconds to indicate to the building occupants that there is still an event active. This will only occur when the
system with System Control is not using the output group. The System Override option is programmable for non-voice output groups on
a per output group basis through the panel output group programming menus and in HFSS Honeywell Fire Software Suite. In these
places the option is called Allow System Override and defaults to YES. It is also possible to not reactivate the output groups every 30
seconds when System Override is active on a per system basis. This option is programmable in HFSS Honeywell Fire Software Suite.
There are times when you would not want to allow System Override for an output group. For example: fire is programmed to an elevator
relay to bring the elevator to the bottom floor for fire only. If fire and EVS are active with EVS being the higher priority event, you still
need the elevator to move to the bottom floor and only audible and visual notification appliances must be overridden. In this case, the
output group assigned to the relay would be set to NO on the Allow System Override setting. See Section edit group properties.
10.5.3 Event Priority
Each event type (see Table 10.1) has a priority level assigned to it. When more than one event type is active, the panel uses the Event Pri-
ority Table to determine which event mapping to use to control output groups. The Event Priority Table can be modified using HFSS
Honeywell Fire Software Suite. It is strongly recommended that before each installation a risk analysis is done by the stake holders
(property owners, AHJ, occupants, etc.) to determine which events take precedence over others.
The Emergency LOC Alarm entry in the Event Priority Table encompasses all EVS Alarm Events that can be activated from an LOC
(LOC Mic Triggered EVS Alarm and LOC EVS 1 Alarm through LOC EVS 8 Alarm). By default, these events do not have a priority -
they can be activated in any order. A programming option in HFSS Honeywell Fire Software Suite exists to force a priority scheme for
the LOC EVS Alarm Events. When this option is enabled, the lower numbered the EVS event is, the higher priority it has (e.g. LOC
EVS 1 Alarm is higher priority than LOC EVS 8 Alarm). With this priority scheme, once a higher priority EVS Event has been activated,
an EVS reset must be performed before a lower priority EVS Event can be activated.
The Event Priority Table contains the following events for modification:
