The start-up condition for the different modes is shown in the following two diagrams (Random Restart
for AZ4500 Series and Random Restart for AZ6500 Series). This function allows for the random restart
of Zonelines in the event of a power outage. The restart delay will reduce the initial inrush current from
the building to help prevent a second power outage. The controls will revert to settings established prior
to the outage.
The Random Restart function is effective in the Class 2 mode.
