• External I/O cable
IMPORTANT:
• Off,input, and output of the exter nal I/O terminal 2
and 3 can be switched by configuring the setting. The
default of EXT I/O terminal 2 and 3 is “Off”. It is possi-
ble to determine whether or not to receive input from
EXT I/O terminal 2 and 3 (ALARM IN2, 3) by selecting
“Off”, “Alarm input”, “Alarm output” or “AUX output”
for “Terminal alarm 2” or “Terminal alarm 3” on the
[Alarm] tab on the “Alarm” page. Refer to the
Operating Instructions on the provided CD-ROM for
further information.
• WhenusingtheEXTI/Oterminalsastheoutputtermi-
nals, ensure they do not cause signal collision with
external signals.

(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)
• ALARMOUT,AUXOUT
Output specification: Open collector output (maxi-
mum applied voltage: 20 V DC)
Open: 4 V - 5 V DC by internal pull-up

heard from the speaker.
• Audio output cable
Connect a stereo mini plug (ø3.5 mm). (Audio output is
monaural.) Use an external speaker with amplifier.

this cable. When a monaural mini plug is connected,
audio may not be heard.
When connecting a monaural speaker with amplifier,
use an optional conversion cable (mono-stereo).
