※ When alarm is entered in a specific channel, the relevant video channel will be displayed.
※ Input OFF mode =”0”, Input ON mode =”1” (The GND and the Inx produce a short circuit)
※ The relevant video channel will not be displayed when the alarm signal is entered into a channel
having signal attenuation.
④-① Alarm Input
The GND and the Inx open or produce a short circuit by using a contact signal (switch, relay) that
does not receive electric signal. When an alarm is produced by a foreign alarm input, the relevant
channel will be displayed. When pressing other buttons during the Alarm Hold time, the alarm will be
cleared.
④-② Alarm Clearance
When the external control data (alarm input) is eliminated, it returns to the last display mode
which had been displayed before the external data has entered after the Alarm Hold time. You can
set the Alarm Hold time as following steps: SETUP MENU → SYSTEM MENU → ALARM HOLD.
