v Connect an external device to the EXT I/O terminals. Strip range When connecting an external device, remove 9 mm - 10 mm {11/32" - 13/32"} of the outer jacket of the cable and twist the cable core to prevent the short circuit first. Specification of cable (wire): 22 AWG - 28 AWG 9 mm - 10 mm {11/32" - 13/32"} Single core, twisted * Check whether the stripped part of the wire is not exposed and is securely connected. Terminal 4: GND Terminal 3: Alarm input/Alarm output/ AUX output 4 3 2 1 Terminal 1: Alarm input Terminal 2: Alarm input/Alarm output Important: • Do not connect 2 wires or more directly to a terminal. When it is necessary to connect 2 or more wires, 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 output AUX output Output specification: Open collector output (maximum applied voltage: 20 V DC) Open: 4.5 V - 5.5 V DC by internal pull-up Close: Output voltage 1 V DC or less (50 mA or less) • Alarm input Input specification: No-voltage make contact input (4.5 V - 5.5 V DC, internally pulled up) OFF: Open or 4.5 V - 5.5 V DC ON: Make contact with GND (required drive current: 1 mA or more) 21
