Understanding How Relays and Alarms React to a Power Outage

The DX8100 server might experience an external AC power outage that impacts how the relay and alarm features function.
•Power outage: Relays configured as NO are closed if the DX8100 is server is shut down by a power outage, or the AC cord is unplugged.
•Power button: Relays configured as NO are closed if the DX8100 power button is pressed and held down.
In the scenarios above, a relay will remain closed as long as the DX8100 is powered down. In this case, alarms or sirens connected to the relays
might produce a false alert.
