Abstract

An alarm system includes a detector arranged in connection with a holster for carrying a force instrument, the detector detecting, if the force instrument is removed from the holster; information on the situation is produced on the basis of the identification and relayed to the user'"'"'s control room so that a message is relayed to the communication unit of the user of the force instrument, the communication unit relaying the message further to the control room via a base station. The detector is adapted to detect the existence of the force instrument in the holster, its missing from or its movement out of or into the holster. A detector-cpu is adapted to receive a signal or message from the detector and forms at least part of the contents of the message on the basis of the signal or message, the detector-cpu being adapted to control the communication unit to transmit the message.

Claims

1. An alarm system, comprising:

a detector (10) connectable with a holster of a force instrument, the detector being adapted to detect a removal of the force instrument from the holster;

a means of communication having am ambient listening property, and

a detector-cpu adapted to receive a signal from the detector, the detector-cpu being configured to form at least part of a content of a message on the basis of the signal and to control the means of communication to transmit the message to a control room via a base station,

wherein the control room is configured to switch on an ambient listening property of the means of communication so that conversations or shots in the vicinity of the user of the force instrument are listenable.

2. The alarm system according to claim 1, wherein the detector-cpu is programmable and/or configurable.

3. The alarm system according to claim 1, wherein the message contains information that indicates at least one of:

“

who”

, “

what”

, “

where”

, “

when”

, “

in which situation”

, and “

how the situation progresses”

.

4. The alarm system according to claim 3, wherein the message contains classification or identification information on the force instrument.

5. The alarm system according to claim 1, wherein the alarm system is configured to make use of the message properties of a data communications network used by the means of communication.

6. The alarm device according to claim 5, wherein the data communications network is any of a Tetra, Tetrapol, and a P25 network.

7. The alarm system according to claim 1, wherein the message is in text format.

8. The alarm device according to claim 7, wherein the text format is an SDS message.

9. The alarm system according to claim 1, wherein the message contains information formed by the detector-cpu and information formed by the means of communication.

10. The alarm device according to claim 1, wherein the control room is further configured to record the conversations or shots.

11. An alarm device, comprising:

a detector connectable with a holster (2) of a force instrument, the detector being adapted to detect a removal of the force instrument from the holster;

means of communication configured to transmit a message to a control room;

a detector-cpu adapted to receive a signal from the detector, the detector-cpu being adapted to form at least part of the contents of the message on the basis of the signal and to control the means of communication to transmit the message; and

means for switching, as a response to a command given via a communication network, the means for communications to a listening mode so that conversations or shots in the vicinity of a user of the force instrument are listenable in the control room.

12. The alarm device according to claim 11, wherein the connection between the detector and the detector-cpu wireless.

13. The alarm device according to claim 11, wherein the connection between the detector-cpu and the means of communication is either wired or wireless.

14. The alarm device according to claim 11, wherein the detector-cpu is fitted into one of the following:

a separate monophone, a headset, and a transmission button.

15. The alarm device according to claim 11, wherein the force instrument is one of a hand gun, and a pistol.

16. The alarm device according to claim 11, wherein the force instrument one of pepper spray, tear gas spray, and an electrical paralyzer.

17. The alarm device according to claim 11, wherein the detector-cpu is configured to request positioning data from the means of communication.

18. The alarm device according to claim 17, wherein the positioning data comprises GPS coordinates.

19. The alarm device according to claim 11, wherein the detector-cpu is programmable and/or configurable.

20. The alarm device according to claim 11, wherein the control room is further configured to record the conversations or shots.
