declares an alarm at a location, another alarm will not be triggered at that
location for three seconds.
Intrusion detection
Cutting the fence fabric produces a high amplitude signal that exceeds the
Threshold. The first time the detection signal exceeds the Threshold, the Event
Count is incremented, and the Alarm Window time count begins. The Event
Window time setting must lapse before another Event will be counted. Each time
the Event Count is incremented the Alarm Window time count is reset to zero.
When the Event Count reaches the specified value within the Alarm Window time
setting, the system generates a sensor alarm. If a subsequent Event is not
recorded before the Alarm Window time runs out, the Event Count and the Alarm
Window reset to zero.
When an intruder attempts to climb over the fence, or lift the fence fabric, a large
number of energy pulses rapidly occur causing the received signal to exceed the
Threshold. When the signal first exceeds the Threshold, the Event Count is
incremented by one, and the Alarm Window time count begins. Typically, during
a climb or lift type intrusion, the received signal remains above the Threshold as
a result of the continued flexing and stressing of the fence fabric. The initial
contact with the fence activates the Event Window time counter. Each time the
Event Window time is reached, and the received signal strength remains above
the Threshold, the Event Count is incremented by one. Each time the Event
Count is incremented the Alarm Window time count is reset to zero. When the
Event Count reaches the specified number within the Alarm Window time period,
the processor generates a sensor alarm at that location.
Initial processor setup
It is recommended to do the initial setup at the processor location using a direct
USB connection to the UCM.
Note: An enclosure tamper condition must exist to enable UCM communication
via a USB connection.
Note: The proces
sor’s Address and Network Configuration settings can be
adjusted only through a direct USB connection.
Connecting the UCM via USB
1. Open the enclosure cover and connect the UCM computer to the processor
via USB (T3).
2. Start the UCM software (for the UCM Connect dialog displays, see Figure 64
on page 58).
