Connecting the Alarm Input/Output Cable Alarm Input Connect the cable to sensors such as infrared sensors, door sensors, metal sensors and manual switches. Ⅵ Input Requirements ● Non-voltage relay NPN open collector input ● Polarity of input detection can be selected using a software ● Make/break (500 ms and above) ● Circuit current of 1 mA during low-level input ● Applied voltage of 3.3 V during high-level input This unit DC3.3 V R Input 1 or Input 2 OUT Sensor example (1) VCC R 3.3 V 1 mA GND GND (Alarm input equivalent circuit) Sensor example (2) Relay switch, etc. OUT GND Alarm output Connect to alarm devices such as alarm, indicator, light or buzzer. Ⅵ Output Requirements ● NPN open collector output equivalent (Refer to the INSTRUCTIONS (Setting) on procedures to set the output logic. ) ● Allowable applied voltage: DC 12 V and below ● Allowable inflow current: 50 mA ● Momentary (100 ms to 5000 ms) output (Refer to [INSTRUCTIONS (Setting)] for procedures to set the time. ) This unit Output 1 or Output 2 Alarm device (example) DC 12 V IN R GND (Alarm output equivalent circuit) GND Note: ● Connect the GND cable of the camera to the GND terminal of the alarm device. 13
