Alarm Connectivity
When a signal is input to Alarm Inputs 1 through 32 (Alarm connector pins 1 through 12 and 15 through 25, Alarm/Control connector pins 1 through 9), recording and camera images are shown according to the settings.
When alarm devices such as a buzzer or indicator are installed externally, connect them to the Alarm output (Alarm/Control connector pin 21).
