Operation during transmission
AF921 can transmit the following messages to the telephone numbers set in the list:
6 vocal messages that can be directly recorded by the user.
6 SMS 24-alphanumerics messages that can be directly made by the user.
10 SMS pre-programmed technical alarms (control panel low battery; power failure; GSM range failure for over
15 minutes; no successful call on the PSTN line; periodical call, SIM expiry).
As soon as the control panel enters the alarm status, it enables the set of calls by dialling the first number
associated to the related alarm message.
Depending on the vocal messages, it behaves as follows:
If the called person answers, the message is repeated twice (4 times if the number was stored by placing *
before). At the end, a 60s-pause is introduced; during this time the called person can send the following
command by using the keypad of his/her DTMF telephone.
Keys pressed on the
telephone of the called

Table 1
If the called person does not answer, the control panel calls the following number and so on. The numbers
with negative result (8 rings without any answer) are called three times again.
Note: The transmission is made on the line selected as the priority line (GSM or PSTN); if this is not available, the
transmission is made on the secondary line.
Concerning the SMS messages programmed by the user, each command makes the related message to be sent
immediately; whereas, the SMS technical messages (stored by default) are sent automatically upon occurring the
proper conditions.
