Intrusion detection
The Senstar LM100 system guards against three intrusion scenarios:
•
•
An intruder attempting to cut through the fence.
•
An intruder attempting to climb over the fence.
•
An intruder attempting to crawl under the fence by lifting the fence fabric.
In local control mode, the relay that signals an intrusion alarm resets automatically when the event
is over or when the relay Hold Time expires, whichever is longer. The relay Hold Time can be set
to values ranging between 125 mS and 10 seconds.
is over or when the relay Hold Time expires, whichever is longer. The relay Hold Time can be set
to values ranging between 125 mS and 10 seconds.
Cut 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
luminaire reports a sensor alarm to the gateway. If a subsequent Event is not recorded before the
Alarm Window time runs out, the Event Count and the Alarm Window reset to zero.

luminaire reports a sensor alarm to the gateway. If a subsequent Event is not recorded before the
Alarm Window time runs out, the Event Count and the Alarm Window reset to zero.
Climb detection
When an intruder attempts to climb over the fence, or lift the fence fabric to crawl under, 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 gateway reports a sensor alarm at that location.

Initial gateway setup
Senstar recommends that the initial setup be done at the gateway location using a direct USB
connection to the UCM.
