Abstract

The invention concerns a method of controlling a hazard alert system with a control device and multiple release mechanisms connected to the control device, wherein the release mechanisms are each connected to at least one alarm device. The initialisation step consists of identification data being assigned to the release mechanisms, and then a control signal is transmitted by the control device to activate or deactivate the alarm devices to all the release mechanisms, wherein the control signal transmits identification data from one or more release mechanisms, and the identification data transmitted by the control device is compared, by the release mechanisms, to the identification data assigned to them. If the release mechanisms determine that the identification data compared with one another matches, they send a control signal to activate or deactivate the alarm devices connected with them, so that the alarm devices are activated or deactivated synchronously. In addition, the invention relates to a corresponding hazard alert system.

Claims

1. A method for controlling a hazard alert system involving a control device (10) and multiple release mechanisms (12) connected to the control device (10), wherein the release mechanisms (12) are each connected to at least one alarm device (18), comprising the steps of:

as an initialisation step, identification data is assigned to the release mechanisms (12);

a control signal for activating or deactivating the alarm devices (18) is transmitted by the control device (10) to all the release mechanisms (12), wherein identification data of one or more release mechanisms (12) is transmitted by means of the control signal;

and the identification data transmitted by the control device (10) is compared by the release mechanisms (12) with the respective identification data assigned to them;

if the release mechanisms (12) determine that the sets of identification data compared with one another match, they transmit a control signal for activating or deactivating the alarm devices (18) connected to them, so that the alarm devices (18) to be activated or deactivated are activated or deactivated synchronously.

2. The method according to claim 1, characterised in that the acoustic signal for activating or deactivating the alarm devices (18) can be transmitted by the control device (10) to all the release mechanisms (12) periodically.

3. The method according to claim 1, characterised in that the control signal for activating or deactivating the alarm devices (18) is transmitted to the release mechanisms (12) by the control device (10), if at least one release mechanism (12) has previously sent out a danger signal to the control device (10).

4. The method according to claim 1, characterised in that the control device (10) transmits the identification data to at least those release mechanisms (12) that have previously sent out a danger signal to the control device (10) by means of the control signal for activating or deactivating the alarm devices (18).

5. The method according to claim 1, characterised in that a communication address clearly identifying each of the respective release mechanisms (12) is assigned to the release mechanisms (12) as identification data.

6. The method according to claim 1, characterised in that multiple groups of release mechanisms (12) are formed, wherein a common respective communication address is assigned to the release mechanisms (12) in a group as identification data.

7. The method according to claim 1, characterised in that the release mechanisms (12) are connected in series to a control line (14) of the control device (10).

8. The method according to claim 1, characterised in that electric power is also supplied to the release mechanisms (12) via the control line.

9. The method according to claim 1, characterised in that the release mechanisms (12) are hazard warning devices (12).

10. The method according to claim 9, characterised in that the hazard warning devices (12) are fire alarms, in particular smoke detectors.

11. The method according to claim 1, characterised in that the alarm devices (18) are visual and/or acoustic alarm devices (18).

12. The method according to claim 1, characterised in that the control device (10) is a fire alarm system control panel (10).

13. A hazard alert system comprising:

a control device (10) and multiple release mechanisms (12) connected to the control device (10) via a control line (14), which, in turn, are each connected to at least one alarm device (18), wherein the release mechanisms (12) each have a storage device, in which the identification data assigned to the respective release mechanisms (12) is stored, wherein the control device (10) has a transmitter, via which a control signal for activating or deactivating the alarm devices (18) can be transmitted to all the release mechanisms (12), wherein identification data of one or more release mechanisms can be transmitted with the control signal, and wherein the release mechanisms (12) each have a comparing device, which is designed to compare the identification data sent out by the control device (10) with the respective identification data deposited in the storage device, and wherein, if the identification data compared by the latter matches, the release mechanisms (12) are designed to transmit a control signal to activate or deactivate the alarm devices (18) to which they are connected, so that the alarm devices (18) to be activated or deactivated are activated or deactivated synchronously.

14. The hazard alert system according to claim 13, characterised in that the control device (10) includes a receiver, which is designed to receive a danger signal emitted by the release mechanisms (12).

15. The hazard alert system according to claim 13, characterised in that a communication address clearly identifying each of the respective release mechanisms (12) is assigned to the release mechanisms (12) as identification data.

16. The hazard alert system according to claim 13, characterised in that multiple groups of release mechanisms (12) are formed, wherein a common respective communication address is assigned to the release mechanisms (12) in a group as identification data.

17. The hazard alert system according to claim 13, characterised in that the release mechanisms (12) are connected in series with the control line (14).

18. The hazard alert system according to claim 13, characterised in that electric power is also supplied to the release mechanisms (12) via the control line (14).

19. The hazard alert system according to claim 13, characterised in that the release mechanisms (12) are hazard warning devices (12).

20. The hazard alert system according to claim 19, characterised in that the hazard warning devices (12) are fire alarms, in particular smoke detectors.

21. The hazard alert system according to claim 13, characterised in that the alarm devices (18) are visual and/or acoustic alarm devices (18).

22. The hazard alert system according to claim 13, characterised in that the control device (10) is a fire alarm system control panel (10).
