Figure 2. Ferrite Bead Installation
* * * CAUTION * * *
To meet FCC requirements, the alarm and contact closures must have
a ferrite bead installed on each pair of wires leading from them. See
Section 2.5.2 and Figure 2-2 for instructions on their installation.
There are 3 ferrite beads packed with the unit. One of these is for the
alarm relay output, and two are for the contact closures.
