Figure 9 - AND and OR partitions
demonstrates the use of AND and OR with the partitions, where each partition has a room in
common with another partition. The
icon visualises when the alarm is set off in case of an intrusion in the armed partitions.
Notice how the alarm signals of the room in common (Room B) are strongly influenced by the logical combination between partitions
S1 and S2, while the ones not in common behave traditionally.

3.4.5 Remote activation of commandable outputs free of charge
If the control panel is equipped with a GSM module and the GSM responder has been enabled, a valid SIM card can be used to make
activations remotely with no additional costs.
This function is based on the Caller ID of the telephones calling to carry out a quick activation of the programmed commandable
outputs. During the programming, the commandable outputs are associated with a cell phone number memorized in the control panel
(one of the ones used to send the alarms and other functions).
IMPORTANT!
The same telephone number may command multiple outputs. Just one output can be commanded by multiple
telephone numbers.
The operating principle is the following:
1. The GSM number of the control panel is called using the telephone number memorized.
2. The call is ended before 3 rings to avoid costs.
3. All the associated commandable outputs are activated: the pulsed ones for about one second (typical application of a gate
opener), commutable ones or bistable ones change status and remain active until they are deactivated by sending the relative
command via SMS.
4. To confirm reception of the command, the control panel calls the number that originally called for a few seconds. This phone call
must not be answered in order to avoid having the cost charged to the control panel SIM card.
3.4.6 Environmental listening
When there is a vocal keypad in the alarm system, it is possible to listen, via telephone, to what is going on in the room where it is
located. If the system has multiple vocal keypads, then a selection may be made, from time to time, as to which room the user wishes
to monitor.
The environmental listening remains active for about a minute and a half before being automatically interrupted. If so desired, the
listening can be interrupted sooner by pressing the “
*
“ key.
In addition to listening, it is also possible to speak through the keypad loud speaker. The communication is one-way (one either speaks
or listens), but it is possible to switch between "speak" and "listen" as desired by pressing the "0" key of the telephone each time.
