White we're on the subject of
di-
alers,
we
should point
out
that, es-
pecially in larger towns and cities, a
fire or police department
will
not re-
spond to
a
recorded message. You
should have
the
unit call a neighbor.
or a central monitoring
system.
Dicon
has
set
up a central
monitoring system
to accept emergency
responses.
While
the price for the
service
is fairly
standard,
it's not
cheap:
about $15 per
month. However, the people at the
central
station
are
trained and there-
fore can conceivably get
help to you
quicker
-and they're
always
home.
Perhaps more
important,
they
receive
the necessary information in digital
form for speedier responses.
Setting
up
the
system
The basic Dicon
9000 is meant to
cover
two doors
or
windows.
One of
its most obvious
features
is that it is
very
easy
to
set up. A
voice syn-
thesizer guides
you through
the pro-
cess.
The first setup task
is to install
batteries
in the remote transmitters
and to
plug the base unit
in. As soon
as power
is supplied to the base
unit, it
will ask you to
select
a
3 -digit security
code
using
its very intelligible
voice
synthesizer.
After you enter
your se-
lected code,
it will repeat the
code,
and
will then ask you to connect
the
first module.
Each remote
transmitter
is assigned
a unique
code by the base
unit.
To
o
program the code, a module is re-
moved from the transmitter and
plugged into
the
base
unit. Once the
base
programs
the module
with
a
code, it asks for the second module to
be plugged in. Since each module
code is unique, any alarm can be
tracked down to the exact module and
reported.
The 9000
can
support up to
30
individual modules.
The Dicon 9000's voice syn-
thesizer guides you through the enter-
ing of emergency telephone numbers
and the recording of
your personal
message. Once you complete that
task, you're ready to
test
the
system.
Assuming everything passes the tests,
you can
permanently install the sen-
sors. (See Figs. 18 -20).
The 9000 features 4 security zones.
Zone 1, usually for your entry doors,
can be selected for
immediate or de-
layed alarm.
Zones 2-4 are always
immediate. Any individual
sensor
can
be turned off or bypassed, and
any zone
can
be on or off.
While
most people
contemplating
their
first
alarm
don't see the
need
for
multiple
security zones,
we'll
give a
simple example to
show
why
they are
necessary. If you are
home
alone
and
would like
your alarm
on, you don't
want
to be made a captive
of one
room.
If
all
of your motion detectors
are on one zone, you
can secure the
premises
with a perimeter zone, yet
be
free
to
move
around
inside. If
you
are expecting
someone else to come
home, the entry door on one
zone can
be left on delay, yet
opening any
win-
dows -which are on another
zone-

Note the

trigger
the alarm.
At all times,
sensors
such
as smoke
detectors
and
medical pendants
will
cause an alarm
when triggered,
even
if the system
is not armed.
