FiberPatrol components
Sensor unit
The FiberPatrol sensor unit (see
) generates the laser light signal that is transmitted into
the fiber sensors. The SU collects the backscatter reflections created by vibrations in the protected
fence and analyzes the signals. The SU supports two independent fiber optic sensors (S1, S2) and
can monitor up to 1440 distinct alarm zones. The alarm zones are defined in software, and do not
depend on cable length. The SU operates on 100 to 240 VAC, 50/60 Hz power and can
annunicate alarm conditions with the built in IDS software, contact closure outputs, or via the
Network Manager software. The FiberPatrol sensor unit includes 2 SSD RAID hard drives, as well
as dual redundant power supplies. There is an audible alert output that is activated in the event
that one of the power supplies fails. A pushbutton switch located between the two power supplies
will silence the alert tone.

Fiber connection module
The fiber connection module is contained in a 1 RU fiber patch panel next to the sensor unit in the
equipment rack. It includes a splice tray to hold the fusion splices between the sensor unit and the
two sensor fibers in the lead cable, as well as 2 terminated patch cords that connect to the SU.
The splice tray includes six unused protective sleeves, which are available to provide access to
the dark fibers in the sensor cable. Optionally, a second splice tray can be added for making
connections to any additional fibers that are being used at the site. In some loop configurations, a
dual end module is incorporated into the fiber patch panel. Refer to Chapter 2, Site planning for
additional details.
