6.1.6 Connections of one or more video
cables
The installation is type CDS (Cable
Distribution System), do not connect it to
SELV circuits.
In order to reduce the risk of re, only use
cable sizes greater than or equal to 26AWG.
Suggested coaxial cables are:
• RG59
• RG174A/U UL1354
Pass the coaxial cable(s) through the entry device.
Connect the coaxial cable through a 75 Ohm
BNC male connector (not supplied) to video BNC
connector(s) J6 (and J7).
• Connector J6: Main camera output.
• Connector J7: Infrared camera (if present).

6.1.7 Connections of one or more
optical ber
Use adequate optical ber.
The transmission of video signal or data can be
done by optical ber. In the conguration with
single camera, in the only available optical ber,
is transmitted the video signal and the telemetry
control. In the conguration with double camera, the
telemetry control is present only in the optical ber
No. 1 (No. 1 on the video, visible camera) whereas in
the optical ber No.2 is transmitted the video signal
of the thermal camera.
For Multi Mode ber transmitters, use 62.5/125µm
with a maximum length of 3km. Use a receiver for
Multi Mode ber model: FORXMM01
For Single Mode ber transmitters, use 9/125µm ber
with a maximum length of 69km. Use a receiver for
Single Mode ber model: FORXSM01
For proper installation:
• Identify the optical ber inside the junction box.
