Priority handling of alarm messages is only determined by the panel type. Although a Fire Panel has the highest priority in the system, to give an emergency panel a higher priority, change its panel type to Fire Panel (dipswitch 1) and set its RS485 address to higher priority (1= highest, 32 = lowest).

    50% deviation of the connected load, before a fault is triggered; after a speaker line is calibrated and the found load value (in Watt) is stored, the eXentro ECU automatically applies above percentages to the found load and displays these. For example: when a 500W load on line X (A+B) is found, the deviation options will be displayed as: 25W, 50W, 100W, 150W, 250W.
