ALARM 1~4 : These ports can be used as alarm input or output ports. If used as input ports, alarm input
or day/night sensors can be connect to them. If used as output ports, alarm output signals
can be connect to them.
※
The setting of each alarm input/output port can be changed at the Web Viewer setting
menu.

`
If devices (e.g., flashing light and siren) that exceed the voltage and current specifications are connected by using the open
collector method, it may cause malfunction.
Refer to the “
Alarm Out Wiring Diagram
” when connecting devices such as a warning lamp or a siren.
