1. GENERAL INFO
1.1. DESIGN
MAMBA perimeter system is primary designed t
o
secure perimeter
o
f the
o
bjects, especially fences. It can be used
for

This alarm system generates an alarm when intruder trying t

1.2. PRINCIPLE OF OPERATION
The general principle is based
o
n fact that the de
tectio
n cable
generates small trib
o
electric signal. This signal (sta
tic
electricity) is due t
o
fri
ctio
n between the dielectric and the
co
pper
core o
f the cable. Def
o
rma
tio
n
o
f the cable and
f
rictio
n in the cable will generate signal in the m
o
ment
o
f the
intrus
io
n. If the cable is well c
o
nnected t
o
the fence all fence
w
o
rking like sensi
ti
ve intrusi
o
n de
tector
.
Whenever the intruder will a
tte
mpt t
o
handle any fence
o
r
cable, the system immediately generates an alarm signal.
The sens
o
r is typically
mo
unted directly t
o
the fence
o
r fence p
o
sts (see. Chapter
1.4 Installation requirements and
procedures
). Sensing cable is securely fastened t
o
the fence using a plas
tic o
r metal cable
tie
s. The number
o
f strips is
an im
po
rtant parame
ter for
the
o
verall system behav
io
ur and sensi
ti
vity. Generally: smaller number
o
f the strips is
used t
o fix
the cable it will decrease the sensi
ti
vity
o
f the system and it may cause false alarms.
System is pr
oo
