Ferrite Bead Installation
A Ferrite Bead is required for the TO AP (smaller bead) to FACP Telco Line wires and for the IPDACT Series 24 VDC
(larger bead) Power Supply wires. Each wire must be wrapped twice around the Ferrite Bead at the end closest to
IPDACT Series board.
Note that the following illustration depicts one wire wrapped around the Ferrite Bead. The two wires to the TO AP termi-
nals must be wrapped around one, smaller Ferrite Bead and the -24 VDC and + 24 VDC wires must be wrapped around a
second, larger Ferrite Bead.
