Originally it was recommend to use a separated 12v DC power for FaceStation 2. But, this spec has shown a power cabling distance issue from a number of customer sites.
Therefore, in order to secure a longer power cabling distance, FaceStation 2 power supply spec was changed to use 24v DC power.
The below is a screenshot of the updated FaceStation 2 quick guide.
Please note that this does not mean that the existing 12v DC power supply customer sites should make a change to adopt, and FaceStation 2 supports 12v power input as well. However, it's strongly recommended to use 24v DC power supply to avoid possible power shortage.
Also, 24v DC power adapter as an accessory is going to be supplied for FaceStation 2 use.
Refer to the updated device manual that is attached to this article.
The only devices that should not use a 24v adapter are the following 66 devices that were manufactured in April 2017:
FS2-D serial #542185212 ~ 542185246 and 542339330 ~542339360
Other devices should be compatible with 24v.
