Alarm Functionality
The device has four independent digital inputs for alarm detection.
Alarms are triggered by connecting an alarm input to ground. The alarm input is on HIGH
potential by a pull-up resistor in open state. During an alarm, the device can send an
alarm message
The alarm inputs are buffered, i. e. it is possible that up to five events per alarm input are
temporarily saved and processed separately by the device.
The processing is done by the order of the alarm inputs, i. e. that first all events from
alarm input number one are processed, after that all events from input number two and
so on.

You can query the state of the alarm inputs via AT commands, SMS or DTMF.
AT command
Enter the command AT**IN? via a terminal program or the HSComm terminal window.
The AT command will send the following response:
Enter the command AT**IN? via a terminal program or the HSComm terminal window.
The AT command will send the following response:
OPEN
Not activated, open
CLOSE
Activated, connected to ground
SMS query
The automatic processing of SMS messages must be enabled (see Chapter 6.2.3).
DTMF query
The processing of DTMF tones must be enabled (see Chapter 6.1.2).
The automatic processing of SMS messages must be enabled (see Chapter 6.2.3).
DTMF query
The processing of DTMF tones must be enabled (see Chapter 6.1.2).
6.3.2 Alarm types
Each of the two alarm inputs can be configured either as simple alarm input or als pulse
input. This results in two different alarm inputs:
input. This results in two different alarm inputs:
Simple alarm
Pulse alarm
Pulse alarm
The characteristics and configuration of the alarms are described in the following.
