The system
generates a
pulsed near
ultra-sonic
tone at around
16 Khtz, which
is close to
the limit of
the hearing
range of people
under 25 years
old. This sound
whilst not painful
in anyway, becomes
highly annoying
after 5 10 minutes
exposure. The
result is that
the majority
of under 25s
leave the immediate
area whilst
the majority
of those over
the age of 30
because of natural
age related
hearing loss
either only
just hear or
in most cases
are totally
unaware of the
noise.
The Mosquito
has already
become widely
adopted by police
and local authorities
around the UK
and is being
hailed as one
of the most
effective teenage deterrent tools
in the fight
against teenage
anti-social
behaviour.
The teenage dispersal system
is designed
to be used for
up to 30 minutes
at a time. A
timer is included
with the unit,
allowing the
preprogramming
of up to 8 on/offs
per 24 hour
period. |
There is also
a manual over-ride
button that
will switch
the system on
between programmed
times if required,
for a period
of 30 minutes.
To ensure the
safety of people
exposed to the
Mosquito the
system has been
designed to
comply with
the HSE 2005
report relating
to exposure
to noise in
the work-place.
The Mosquito
has been tested
in relation
to this HSE
report by the
National Physical
Laboratory (NPL)
in London. Test
outcomes documented
by the NPL state
that according
to HSE guidelines,
the sound output
of the Mosquito
will cause no
damage to human
hearing even
with prolonged
exposure and
especially not
within the 30
minute periods
of activation
of the device
as recommended
by Compound
Security Systems
Ltd.

| The
Mosquito
is designed
for
external
use
only,
and
has
a range
of 20
25 metres
with
a 60
degree
angle
of spread. |
| Working
on a
12v
transformer,
the
system
requires
only
a standard
13 amp
domestic
power
socket
and
can
be mounted
with
a security
cage
by a
non-qualified
person
in little
over
an hour. |
| Due
to the
nature
of high
frequency
sound,
there
is no
penetration
of the
noise
of solid
objects,
therefore
no sound
will
be heard
within
the
premises
the
system
is mounted
on OR
within
any
adjoining
properties. |
