5.2.3 Reader Daisy-Chain
One Proximity reader is shared by all elevator control panels in an elevator control application. The
main reader connections are made to a primary LC-502P elevator panel. All other reader
connections to the remaining LC-502P/LC-508P panels are made per the following rules.
1. The reader antenna line must be daisy-chained to all other elevator panel antenna inputs – Pin 1
of TB-5 and TB-6 on the LC-502P/LC-508P panels.
2. The reader ground line must be daisy-chained to all other elevator panel antenna grounds to
provide a standard ground reference for all panels – Pin 4 of TB-5 and TB-6 on the LC-502P/
LC-508P panels.
3. The reader’s positive power line must be connected to the master elevator panel ONLY (Pin 3 of
TB-5 on the master LC-502P/LC-508P panel).
Make the reader connections per the information in Figure 8 on page 14.
