15. Alarm transmission by telephone
In addition to alarms from sirens and signalling devices, the wireless alarm
system can also transmit an alarm via telephone (PSTN, ISDN, GSM). There
are two types of alarm transmission by telephone:
•
Alarm transmission of a digital protocol to a security centre
•
Alarm transmission of a voice message to any telephone
If a connection to a security centre has been established, the centre reception
confirms the alarm transmission. If the alarm is transmitted to a normal
telephone, the called party must acknowledge the alarm transmission to
prevent further dial attempts.
This is the made as follows:
1. The call is received on the telephone and is displayed like any other call.
2. Accept the call.
3. Listen to the complete voice message. A distinction is made here between
different alarm causes.
4. The recorded voice message is repeated
three times
. After the third
announcement, the microphone on the wireless alarm centre is activated
and you can listen in to the monitored room. The following tone dialling
commands are also available.

5. If you are able to take action yourself, acknowledge the alarm
transmission by pressing “5” or “9” on your telephone (DTMF telephones).
6. If you are not able to take action, then end the call or press “5”. The alarm
transmission is continued and other parties are informed.
16. Remote control by telephone
The alarm centre can call you in the event of an alarm. After listening to the
message, you can send commands to the system by pressing your telephone
keypad. The system informs you of the command status by playing short
tones through the telephone. Hang up the telephone when you are finished.
You can also call the wireless centre when no alarms are present in
order to check the system:
1. Dial the number of the alarm system:
You should then hear:
“beep, beep, beep”
2. Enter your user code.
You should then hear:
“beep, beep”
Each of the following commands can be used. Hang up the phone to end the
call.
