High Security Installations; Cable Connectors - Interlogix FlexZone Series Product Manual

Chapter 1: System planning

Cable connectors

The splice kit is used to join two FlexZone cables together, and to join lead-in
cable to sensor cable. The splice kit is also used to make cable repairs. The
termination kit is used in situations where a FlexZone sensor cable is not
connected to another FlexZone sensor cable. In this case, the termination kit is
connected to the end of the sensor cable to enable processor supervision. The
cable connectors are mounted horizontally on the fence using two cable ties.
It is recommended to limit cable repair splices to one splice per 150 m cable
length.

High security installations

The FlexZone sensor can provide redundancy for high-security installations,
providing certain rules are followed. If these rules are followed, then the system
will continue to provide perimeter detection even if one processor fails, or a
sensor cable is cut or if one power supply fails. With this configuration, each 300
m of sensor cable is monitored simultaneously, by two processors.
Note: If a sensor cable is cut, detection will continue with compromised
performance due to the high level of clutter at the location of the cut. In the event
of a cut cable, repairs must be made as quickly as possible to return the system
to its full detection capabilities.
High-security installation rules
•
maximum sensor cable length for one side of a processor is 150 m
•
maximum length of sensor cable between 2 processors is 300 m
•
a minimum of two 48 VDC power supplies (depending on total number of
processors)
•
power supplies must be connected to processors on the ends of the perimeter
•
two Silver Network connections to Network Manager PC at opposite ends of
the loop, OR, star network configuration setup using PoE

km (1.3 mi.) in length.
