Block diagram
The rising edge on the tamper input (1: Event.InputChanged) initiates calling to the
defined telephone number (5: Action.BeginCall) in case the defined condition is met.
The condition (4: Condition.FlipFlopRS) is validated by the intercom restart or entering
the selected code (2: Condition.CodeEntered) on the numeric keypad. If another code
is entered (3: Condition.CodeEntered), the condition will be invalid.
