PRIORITY LEVELS
Three priority levels (High, Medium & Low) are available. For each priority level an output control expression and a tone have to be
programmed. At least one priority level has to be programmed.
The sounder can, for example, have one tones for fire alarm activated somewhere in the whole building (low priority), another sound
type for fire alarm activated on the same story/floor (medium priority) and yet another sound type when the detector plugged in the
base activates fire alarm (high priority).
A control expression with one or more trigger conditions shall be created. If the sounder is activated/sounds for a lower priority level,
the tone will change if the control expression for a higher priority level becomes true.
Two priority levels cannot have the same tone.
