Lock power
There are two cable sockets providing extra lock power (Figure 12 on page 13,
items 22 and 32), if required. The sockets are for easy connection to expander
boards that support the connection, such as the CDC-2DWIF Dual Wiegand
Interface.
Connect a 2-way lock power cable (supplied with the expander board) to one of
the 2-pin plug-in lock power sockets.
Refer to Figure 15 on page 27 for example connections of 2-way lock power
cables from CDC4 to an expander board (items A and C).
