The AC power supply model of MIEN5208 series switches supports
DC110V~370V and AC85V~264V power supply. When using AC model, V can
only input from V1+ and V1-, V1+ is connected to fire line L, V1-connected to

Power failure alarm output
The MIEN5208 series switches support the alarm function, with a normally
open node and a normally closed node. The left side is a normally open node,
the right side is a normally closed node, and the middle one is a common end.
When the switch works normally, the normally open node is powered on and
closed, and the normally closed node is disconnected. When the system is
powered off, the port is dropped, or the ring network is alarmed, the normally
open node is powered off and the normally closed node is closed. The relay
recommended switch load capacity is 1A (24VDC). The user can use the relay
contact to output other external sound and light alarm devices.
