The SED-901 series will accept only card
information such as a Wiegand data
stream from 23 to 80 bits and Cardax
Mifare / 125 data.
This will be processed and passed over
the 900 MHz link. As well as the
transposition of the 4 x normally open
inputs crossed over to the 4 x dry relay
contacts on the remote, and visa versa.
This can be used for separate control of
devices, and works as, Input to follow
Output.
NOTE: YOU MUST ALWAYS WIRE ALL CABLES SHOWN FROM THE SED-901
TO THE ACCESS CONTROL SYSTEM - FAILURE TO DO SO, WILL RESULT
IN THE WIRELESS UNIT NOT WORKING CORRECTLY
