Important: • Do not connect 2 wires or more directly to a terminal. When it is necessary to connect 2 wires or more, use a splitter. • Connect an external device with verifying that the ratings are within the specifications above. • When using the EXT I/O terminals as the output terminals, ensure they do not cause signal col- lision with external signals. • ALARM OUT, AUX OUT Output specification: Open collector output (maximum applied voltage: 20 V DC) Open: 4 V - 5 V DC by internal pull-up Close: Output voltage 1 V DC or less (50 mA or less) • ALARM IN Input specification: No-voltage make contact input (4 V - 5 V DC, internally pulled up) OFF: Open or 4 V - 5 V DC ON: Make contact with GND (required drive current: 1 mA or more) b Connect a LAN cable (category 5 or better, straight, STP*) to the network connector. * PAL models only n Connect the power supply. Important: • The 12 V DC power supply shall be insulated from the commercial AC power.
