Alarm Input/Output Terminal Connection Connect the alarm input/output terminals with external devices, such as a sensor or buzzer. Plug/Unplug the cable while pressing the button as shown in the diagram below. Cable to use ● Shielded cable ● Length of 50 m or shorter 1 2 G2 12 1 OUTPUT INPUT CLASS 2 ONLY FOR USA ISOLATED POWER ONLY FOR EUROPE AND OTHER AC24V ALARM PoE MONITOR OUT 10BASE-T/ SEE INSTRUCTION MANUAL 100BASE-TX CAUTION: NEVER USE PoE AND AC 24V AT THE SAME TIME DO NOT CONNECT TO THE TELEPHONE NETWORK PUSH Push Caution: ● Noises from an external source may cause the camera to malfunction even when the cable used is within 50 m. In this case, move the cable away from the noise source. Alarm Input Terminal Connect this terminal to sensor devices, such as an infrared sensor, door sensor, metal sensor or manual switch. Ⅵ Input requirements ● No-voltage relay NPN open collector input ● Polarity of input detection can be selected using a software ● Make/Break (500 ms and above) ● Circuit current at low level: 1 mA ● Applied voltage at high level: 3.3 V VN-V25U DC3.3 V R INPUT 1 or 2 Terminal OUT Sensor Example (1) VCC R 3.3 V 1 mA G Terminal GND (Alarm Input Equivalent Circuit) Sensor Example (2) Relay Switch, etc. OUT GND Alarm Output Terminal Connect this terminal to annunciating devices, such as annunciators, indicators, lights, or buzzers. Ⅵ Output requirements ● Equivalent to NPN open collector output (Set the output logic using the Internet Explorer) ● Allowable applied voltage: DC12 V and below ● Allowable inflow current: 50 mA ● Momentary (100 ms - 5000 ms) output (Set time using the Internet Explorer (A Page 46)) VN-V25U OUTPUT 1 or 2 Terminal IN Annunciating Device Example DC 12 V R G Terminal GND (Alarm Output Equivalent Circuit) Caution: ● Connect the G terminal of this camera to the GND terminal of the annunciating device or alarm input sensor. 17
