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.
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.
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.  
Note
An enclosure tamper condition must exist to enable UCM 
communication via a USB connection.
Note
The gateway’s Address and Network Configuration settings can be 
adjusted only through a direct USB connection.
