GSM/GPRS module
The Alpha Vision ML can be extended with a GSM/GPRS module. The GSM/GPRS module is a plug-on board
that is powered directly from the main board. The power consumption of the GSM/GPRS is highly
dependent on the GSM network strength. Once the signal strength decreases the GSM/GPRS module will
automatically increase its transmission power and this has implications for power consumption. Under
normal circumstances the power consumption is approx. 30mA but can increase up to 500mA.
Battery test and mains failure
The automatic battery test is done in two ways. A light battery test is carried out every 3 seconds. A heavy
battery test is done every day at 12:00 hours.
Both the AlphaVision ML itself and any existing I/O modules, including power supply perform a battery test.
If during the battery test a battery is defective, the user will be alerted during arming. In the keypad the
text "Information available" will appear on the display. Also, the information (i) LED on the right of the
keyboard will blink to indicate "Information present". Arming with a low battery voltage is possible,
however arming with a mains failure is not.
By pressing the key and entering a user code level 3 or higher the information can be read by pressing
the key and then deleting it at the end by pressing the <#/OK> button. If an I/O module with power
supply is connected, the "Information present" message must be read and erased twice. Once the first
message is read and erased, the AlphaVision ML will send a command to the I/O module to perform an
automatic battery test. If the battery voltage is sufficient, the second time reading and deleting the
message will ensure the message does not appear again.
From firmware v3.60 it is possible to disable the battery monitoring / low battery sensing of the battery
installed in the AlphaVision ML control panel. In the system settings menu option 22 'battery guard' has
been added. If the battery monitoring is disabled, then low battery messages will not be displayed on the
keypad and no alarm event will be transmitted. The system can now also be armed with a low battery of the
control panel. A low battery of connected I/O modules is not included in this option and will always be
displayed and transmitted.
Depending on the selected programming option reporting of a low battery voltage of the Alpha Vision ML
control may or may not not take place immediately. A low battery voltage of the connected I/O modules are
always reported immediately.
Both the AlphaVision ML and the I/O module with power supply mains failure will be detected. Mains
failure is detected within 10 seconds. Reporting a mains failure will occur after 30 minutes.
Telephone line test
If the PSTN dialer is placed and the programming option "Tel-line monitoring" is enabled in the PSTN/GSM
dialer programming then during the light battery test every 3 seconds also the line voltage of the connected
analog telephone line is measured. If the line voltage is below 3 VDC this will be reported directly by the
information (i) LED and flashing phone LED. Using the key the information can be read using a user
code with level 3,5 or 7.
STARTING UP THE ALPHAVISION ML
If all components are installed and connected correctly the AlphaVision ML can be powered up and
programmed. The AlphaVision ML is freely programmable via a LCD or LCD/PROX keypad. See chapter
PROGRAMMING.
Programming the AlphaVision ML with a computer
The AlphaVision ML can also be programmed using a computer or laptop. To program with a
computer/laptop the AlphaTool software (art.nr. 004255) a LAN cable is required. Optionally a
