10.1 Make Local FC-FI Board Connections 10.2 Connect Local Sounders
“Local sounders” are sounders connected directly to
the FC-FI board, as opposed to sounders on the
addressable loop.
Connect the sounders as shown in Fig. 19 (Item 4). The
figure only shows one sounder, but multiple sounders
can be connected in parallel.
The terminating capacitors are included in the shipment.
Fit the capacitors beyond the furthest sounder. The
capacitors can be connected with either polarity. If a
control panel sounder output is not required, connect
the capacitor directly across the sounder output termi-
nals (it is safest to fit the capacitor(s), as this will ensure
no faults are reported).
NOTICE
There is a danger of signal interference
between cable runs.
Take care when laying out transmission
lines to avoid the potential for cross-
coupling between them.
