Bosch Security Systems I 7/05 I F.01U.522.651A
Function
Outgoing calls and reports
(A)
are transmitted over the analog phone network
(4)
by default.
If the voltage on the phone line is too low (static supervision) or after 3 unsuccessful redial
attempts from the control panel
(2)
(dynamic supervision), the ITS-300GSM
(3)
switches to
transmission via the GSM mobile network
(5)
. The information from the control panel is either
transmitted transparently as tones
(A1)
to the dialed number
(6)
or is sent as an SMS
message
(A2)
to an SMS receiver
(7)
if this has been programmed. Phone calls from the house
phone
(1)
can be transmitted via GSM
(A2)
if the analog phone line fails (see Parameters,
digit 4). If necessary, the ITS-300GSM can also transmit own events
,
such as test calls and
fault/restoration of the phone line in the form of an SMS
message
(B)
. Remote programming
(C)
is possible with a cell phone
(8)
.
Initial Set-Up
1) Set jumper (A1=transparent transmission, A2=SMS transmission)
2) Connect antenna
3) Adjust SIM card for ITS-300GSM with cell phone:
3.1) Test GSM field strength via cell phone display at antenna location
3.2) Remove PIN code from SIM card or change to "0000"
3.3) Programming via SIM card if necessary (see Programming)
3.4) Remove SIM card and insert in ITS-300GSM
4) Mount ITS-300GSM in control panel housing
5) Connect cable to control panel:
5.1) red/black cable parallel to battery in control panel (special terminals)
5.2) gray cable to an alarm line
(optionally to transmit phone line fault via GSM)
5.3) yellow cable to house phone connection - Important: Required for full functionality.
5.4) green cable to phone line connection
6) Connect ITS-300GSM to the analog phone network - use screw terminals or phone socket
7) Connect cable plug to ITS-300GSM
8) LED display:
8.1) LED flashes in sequence:
- once: Voltage has been applied
- twice: Device is booked in GSM network
- three times: ITS-300GSM is ready
8.2) LED flashes every 12 seconds: GSM field strength is displayed
once= low field strength to five times= high field strength. If the GSM field strength
is low, improve the antenna location.
8.3) LED lights up during transmission via the GSM mobile network
