persist whilst the input remains in a Non-Normal state. When the input returns to a
normal state the alarm will be cleared.
Normal to Non-Normal (Positive Edge)
This type of triggering may be used in situations where a momentary type input (eg:
shock sensor, PIR etc), is used. Since these types of inputs are momentary any alarm
condition which occurs no matter how short will persist until manually cleared.
Positive Edge triggering is used when an alarm is required to persist after an input
changes from the Normal state to the Non-Normal state.
Non-Normal to Normal (Negative Edge)
This type of triggering may be used in situations where a momentary type input (eg:
shock sensor, PIR etc), is used. Since these types of inputs are momentary any alarm
condition which occurs no matter how short will persist until manually cleared.
Negative Edge triggering is used when an alarm is required to persist after an input
changes from the Non-Normal to Normal state to the state.
