End Module
The detection for each sensor zone is terminated by the end module. The two sensor fibers in the
detecting cable are spliced to two end module fibers. The end module includes 2 SC/APC
connectors, which are cut off with 1 m fiber leads. The end module is fence-mounted inside a
weatherproof enclosure at the end of the detection zone.
Weatherproof splice enclosure
The outdoor-rated weatherproof splice enclosure (p/n F4KT0100) protects the optical components
and field splices for the FP400 sensor system. The enclosure includes two cable ports and sealing
grommets sized for the sensor cable. The splice enclosure can contain up to 12 splices including a
start module, an end module, a start module and end module, or two end modules. It can also be
used to protect the lead-in cable splices at the processor location.
Sensor cable/non-detecting lead-in cable
The sensor cable is telecommunication grade outdoor-rated central loose tube single-mode fiber
optic cable with a polyethylene outer jacket and a waterblock system. The non-armored loose tube
cable is comprised of a central 12-fiber buffer tube and 2 fiberglass reinforced plastic (FRP)
strength members. The sensor cable is also used as the non-detecting lead-in cable for the
connection between the processor and the start module. Sensor detection begins at the start
module of each zone.
Figure 6 illustrates the sensor cable with a fiber designation table indicating
the recommended use of the individual fibers. Sensor cable can be ordered in lengths of 250 m
(820 ft. p/n F4SP0100) and 1000 m (3,280 ft. p/n F4SP0101).

Note Contact Senstar Customer Service if the installation requires additional
dark fibers. Higher capacity sensor cable is available from the factory.
However, the higher capacity cable requires larger splice enclosures to
accommodate the larger cable.
