2.2.8 Wiegand output connection
The S900 provides standard 26-bit Wiegand output by default, which
can be connected to most 3
rd
party access control panels. The S900
connects to the panel just like any card-reader or keypad. The distance
from the controller to the S900 cannot be more than 30 feet. If the
Wiegand signal must be transferred much further, or if electro-magnetic
interference exists, utilize a Wiegand signal amplifier.
