## Abstract

The disclosure relates to an alarm system with a portable identification device and a portable alarm device, wherein the identification device is configured to receive an enquiry signal and in reaction thereto to emit an identification signal, and the alarm device comprises: a touch-sensitive sensor device, an enquiry device, which is configured to emit the enquiry signal and to receive the identification signal, and a control device, the control device being configured: in reaction to the touch signal to emit the enquiry signal by way of the enquiry device, to compare the identification signal received as a reaction to the enquiry signal with a predefined identification in order to carry out an identity check, and to emit an alarm signal if the identity check is negative. The disclosure also relates to a method for triggering an alarm signal.

## Claims

### Claim 1

An alarm system comprising:
a portable identification device and a portable alarm device, wherein
the identification device is configured to receive an enquiry signal and to emit an identification signal in reaction thereto, and
the alarm device includes:
a touch-sensitive sensor device, which is configured to record a touch and convert it into an electrical touch signal,
an enquiry device, which is configured to emit the enquiry signal and to receive the identification signal, and
a control system, which is connected to the sensor system and enquiry system through data technology
wherein the control device is configured to
emit the enquiry signal by the enquiry device in reaction to the touch signal,
compare the identification signal received in reaction to the enquiry signal with a predefined identification,
perform an identity check, wherein the identity check is positive if the received identification signal corresponds with the predefined identification and wherein the identity check is negative if the received identification signal does not correspond with the predefined identification or if an identification signal is not received within a predetermined period of time, and
emit an alarm signal if the identity check is negative.

### Claim 2 (depends on 1)

The alarm system according to claim 1 wherein the predetermined period of time is less than 0.5 seconds.

### Claim 3 (depends on 1)

The alarm system according to claim 1 wherein the sensor device is designed as a capacitive sensor device and has a sensor element that is connected to a voltage source.

### Claim 4 (depends on 3)

The alarm system according to claim 3 wherein the sensor element is flat.

### Claim 5 (depends on 1)

The alarm system according to claim 1 wherein the enquiry device is an RFID enquiry device and the identification device is an RFID transponder.

### Claim 6 (depends on 1)

The alarm system according to claim 1 wherein the identification device and the enquiry device are configured to communicate with each other in an encrypted manner.

### Claim 7 (depends on 1)

The alarm system according to claim 1 wherein the control unit is further configured to emit a trigger signal if the identity check is positive.

### Claim 8 (depends on 1)

The alarm system according to claim 1 wherein the control device is configured to emit the alarm signal in the form of an acoustic signal, an optical signal and/or a haptic signal.

### Claim 9 (depends on 1)

The alarm system according to claim 1 wherein the control device is configured to stop emitting the alarm signal when an identification signal is received and the identity check is positive.

### Claim 10

A method for triggering an alarm signal comprising the steps of:
providing a portable identification device and a portable alarm device,
recording a touch by a touch-sensitive sensor device which is provided in the alarm device, and
emitting an enquiry signal by an enquiry device provided in the alarm device,
performing an identity check by a control device provided in the alarm device, wherein the identity check is positive if the received identification signal corresponds with a predefined identification and wherein the identity check is negative if the received identification signal does not correspond with a predefined identification or if an identification signal is not received within a predetermined period of time, and
emitting an alarm signal by the control device if the identity check is negative.
