Perimeter layout guidelines

Processor synchronization
A group of FlexZone processors that are connected through the sensor cables must be
synchronized to prevent mutual interference. For a fully closed 2 or 3 processor perimeter, one
processor must be set as the Sync Master for the group. The Sync Master generates a
synchronization signal and transmits the signal through its A-side sensor cable. The next
processor receives the Sync signal through its B-side cable, synchronizes itself accordingly and
then sends the Sync signal on to the next connected processor (A-side to B-side). The Sync
Master will not accept a signal from another processor and always restarts the synchronization
process. To set a processor as the Sync Master connect the UCM to the processor and uncheck
the Accept Sync Signal check box.
For an open loop sensor configuration where at least one sensor cable ends with a terminator (not
connected to another sensor cable) the synchronization process is automatic and requires no
configuration changes. Each processor that is set to Accept Sync Signal will receive the Sync
signal through its B-side cable, synchronize itself accordingly and then send the Sync signal on to
the next connected processor. By default, the processor on the end of the perimeter that is
connected to the next processor through its A-side cable will generate the Sync signal that starts
the synchronization cycle.
Alarm monitoring
Alarm monitoring is site specific and depends on whether you are using relay outputs for alarm
reporting (Local control mode) or Silver Network based alarm reporting (Remote control mode).
Each processor has four user-configurable Form C relay outputs. In Local control mode, the four
relays are used to signal alarm and supervision conditions. For network based processors, alarm
data is carried over the network cables and the four relays are available as output control points
from the security management system (SMS).
NM Mode
The FlexZone processor can be configured to report alarm and supervision conditions through the
UltraLink modular I/O system. In NM Mode, the UltraLink I/O processor acts as the Network
Manager, providing alarm outputs for a connected network of up to eight Silver devices. In NM
Mode, the Silver devices do not require a connection to a PC running Silver Network Manager
software. Sensor alarms and supervision conditions are assigned to UltraLink I/O outputs (relay or
open collector). When an alarm occurs on a connected sensor, the corresponding UltraLink I/O
output is activated (see
for additional details).
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.
Note
Only one processor in a connected group can be set as the Sync
Master or mutual interference will occur.
Note
Senstar recommends limiting cable repair splices to one splice per
150 m (492 ft.) cable length.
