How 'Cause and Effect' interact with 'Day and Night Modes'
This page illustrates the immediate and delayed Cause and Effect interaction with Day and Night modes.
¨
The immediate actions of a zone will always occur immediately in the event of a fire from the zone regardless of Day/Night mode status.
¨
The delayed actions of a zone will occur after the day mode delay has timed out when 'Day mode' is active. Additional verify delay will apply if it is set up and made active
during day mode delay.
"
By configuring the immediate actions same as delayed actions it is possible to use the Day/Night mode switching to switch sensor sensitivity states.
