The activation parameter of the external input defines how long the input is to be considered triggered. If set to
“Continuous”, the input is triggered as long as its state is asserted. If set to “Impulse” the input is triggered immediately
when its state is asserted, and is not cancelled when the state is no longer asserted. Please note that if activation is set to
“Impulse”, it is not possible to cancel the alarm from the same input. Cancellation must be performed via an access unit or by
asserting a different external alarm input with type set to “Cancel”.
The output parameter defines which alarm output (if any) to trigger when the external alarm is asserted. If this is set to
“None”, no alarm outputs will be triggered based on this external alarm input.
Alarm synchronisation sets the zone or set of zones, alarm tone and alarm priority as well as some advanced options for the
alarm synchronisation input. This input is typically used to synchronise a sound or alarm in the GA system with an external
trigger, for example fire bells. The advanced options include the possibility to set the waveform generator for MPAL alarm
tones and which alarm output to assert when the alarm synchronisation input is active. The waveform must be either “Sine”
or “Triangle” for a sine-wave generator or triangle-wave generator respectively.
