Alarm Input/Output Cable Connection Connect the alarm input/output cables with external devices such as a sensor, buzzer, etc. Signal name Alarm input 1 Alarm input 2 Alarm output 1 Alarm output 2 GND Cable color Pink Blue Orange Yellow Brown Cable to use ● Length of 50 m or shorter ● UL1007, UL1015 or equivalent products ● AWG#22 - AWG#18 or equivalent products LAN cable Wind the 3 waterproof tape Alarm input/output cables Solder or crimp Insulation tape Alarm Input Connect this terminal to sensor devices, such as an infrared sensor, door sensor, metal sensor, manual switch, etc. 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: 0.3 mA ● Applied voltage at high level: 3.3 V Camera unit DC3.3 V Input 1 R or Input 2 Sensor example (1) OUT VCC R 3.3 V 0.3 mA GND (Alarm input equivalent circuit) GND Sensor example (2) Relay switch etc. OUT GND Alarm Output Connect this terminal to annunciating devices, such as annunciators, indicators, lights, buzzers, etc. Ⅵ Output requirements ● Equivalent to NPN open collector output (Set the output put logic via the Internet Explorer) ● Allowable applied voltage: DC12 V and below ● Allowable inflow current: 50 mA ● Momentary (100 ms to 5000 ms) output (Set time via the Internet Explorer (A Pg. 50)) Camera unit Example of annunciating devices Output 1 DC 12 V or Output 2 IN R Noteɿ ● Noises from an external source may cause malfunctions even when the cable used is shorter than 50 m. In this case, use a shielded cable or move the cable away from the noise source. GND GND (Alarm output equivalent circuit) Noteɿ ● Connect the GND cable of this camera to the GND of the annunciating device. 27
