stored in a memory area that cannot be
erased when the power is removed.
These
messages are used to inform the user of the
present state of the system
(
alarm
,
fault
,
arming
or
disarming
).
It can be set to do calls or to send an SMS to
all events or to selected events
(
i.e
alarm
,
fault
e.t.c
)
or in combination of events
(
i.e.
During an alarm and fault
).
In order for someone to be able to send a
command to the GSM module via SMS or by
calling, the number must be stored in the
memory and remote access must be enable
for that number.
Alternately you can activate
t h e s e l e c t i o n s o t h e u n i t w i l l a c c e p t
commands from all the telephone numbers
.
Please note that the telephone number must
be stored without the country code in the
beginning.
If the monitored area is in another
country then the number must be stored
including the country code in the beginning.
Finally the GSM will respond to an incoming
c a l l a f t e r 1 5 s e c o n d s , i f t h i s o p t i o n i s
selected. If it is not selected then the GSM
will permit the line to ring for a few seconds

OUTGOING SMS
In case of an outgoing SMS, it will contain
the type of event, the source, the description
of the event and the date and time of the

OUTGOING CALLS
During an outgoing call, when the call is
a n s w e r e d f i r s t t h e w e l c o m e m e s s a g e i s
reproduced, then there is a beep sound and
finally the message concerning the state of
t h e s y s t e m i s p l a y e d f o r 4 t i m e s .
I f , f o r
example the system is disarmed and there is
a f a u l t t h e n t h e m e s s a g e
“
FA U LT
,
D I S A R M E D
”
w i l l b e h e a r d f o r 4 t i m e s
whereas if there is an alarm and the system
is armed the message “
ALARM
,
ARMED
”
will
b e h e a r d f o r 4 t i m e s
.
A t t h e e n d o f t h e
message a beep will be heard and after 5
seconds the line will be closed.
If during the
message period any key apart from the
“#”
key is pressed, on the receiving telephone
,
then 3 beeps are heard and the line is closed
without any other action. If the
“#”
key is
pressed then 2 beeps are heard, the line is
closed and the GSM dialer does not dial any
other numbers since one number has

prevent spending credit from the SIM card
and to prevent disturbing the other numbers.
It is stressed that if the call is dismissed by
the user or the user does not pick up the
phone the call might still be answered by the
automatic telephone answering service, if it
is enabled by the service provider. In this
case the call will still be credited.
For this not
to happen, the telephone forwarding to the
t e l e p h o n e a n s w e r i n g s e r v i c e m u s t b e
disabled. This is the main reason why it is
suggested to use SMS instead of calling.
Also the use of SMS is more simple than
using calls.
INCOMING CALLS
Regarding calls toward the GSM module it is
require to enter one of the 2 codes (user or
technician) in order to retrieve the status of
the system. If an action is required (system
arming) e.t.c) then an additional code is also
required. When a call is placed to the GSM
and the GSM module picks up the line is will
issue one beep. After the beep is heard we
must enter the user or technician code using
our handset keyboard.
If the code is wrong
t h e n 3 b e e p s a r e h e a r d a n d t h e l i n e i s
terminated. If the code is correct then the
system status message is replayed 4 times.
When the messages finish a beep is heard
and the GSM waits for another code entry.
N o w w e c a n e n t e r t h e u s e r c o d e , t h e
technician code or one of the 50 general
purpose codes.
If the code is wrong then 3
beeps are heard and the line is terminated. If
t h e

t h e n
t h e
action(depending on the code) is executed, 2
beeps are heard and the new system status
message will be replayed 4 times after which
the line will be terminated.
INCOMING SMS
A command can also be sent by using SMS.
Each command must have a specific format
to be accepted by the GSM system.
In any
case, the command must also contain a valid
code.
SMS commands can be used to do

activation/diactivation of specific
outputs of the BS-468 panel) or used to get
retrieve status information of the system.
For

command also contains the main user code.
Also an SMS can be used to request the
status of the system. In this case just send
the code of the main user and nothing else.
Finally, the SMS can also contain one of the
50 general purpose codes. In this case no
