Whenever a SmartSwitch enters an emergency state, some relays will switch off.
SmartSwitch is provided with a UL 924 emergency contact input. When an active emergency contact is received, all non-emergency circuits in the SmartSwitch are forced to switch off while all user-selected emergency circuits in the panel are switched on. During an emergency state the LCD will display a message advising the “Emergency Input Is Active” and the menu will lock-out all ability to access the SmartSwitch menu. After normal power is restored, the SmartSwitch will restore to the configured DMX Loss Behavior mode.
