Abstract

Monitoring and mass notification systems, such as fire alarm systems, for use in occupied structures, and more particularly to wireless monitoring and mass notification systems include wireless base units that can be modular in design. This allows horns, mini horns, strobes, and audio messaging modules (e.g., speakers) to be physically plugged into the wireless base unit creating a unit with the appearance of a single physical unit. Preferably standardized plugs are used. In some cases, visual and audio modules (i.e., notification devices) have their own battery pack or external power interface. Each wireless base unit can optionally function as a repeater if it has dual transceivers (master transceiver and slave transceiver).

Claims

1. A monitoring and mass notification system, comprising:

a control unit for broadcasting alert messages via addressable wireless links;

a wireless base unit having a notification interface, a slave transceiver for receiving the alert messages from the control unit, and an identification address for distinguishing the wireless base unit from other wireless base units; and

a notification device having a base interface for plugging into the notification interface of the wireless base unit and sending notification device information to the wireless base unit indicating a type of the notification device;

wherein the notification device receives a notification command from the wireless base unit and the notification device generates an alarm notification in response to receiving the notification command from the wireless base unit based on the broadcasted alert messages associated with the identification address;

wherein the wireless base unit reports the notification device information received from the notification device to the control unit.

2. The system of claim 1, wherein the notification device is a horn, a strobe, or a speaker.

3. The system of claim 1, wherein the wireless base unit comprises a rechargeable battery or a non-rechargeable battery.

4. The system of claim 1, wherein the notification device is independently powered from the wireless base unit.

5. The system of claim 1, wherein the notification device is powered by a battery, an external power source, or an energy harvesting unit.

6. The system of claim 1, wherein the wireless base unit is configured to receive the notification device information for the notification device when the notification device is plugged into the wireless base unit.

7. The system of claim 6, wherein the wireless base unit is configured to report the notification device information to an alarm panel via the control unit for programming the notification device.

8. The system of claim 6, wherein the wireless base unit is configured to send a notification status check to the notification device in order to monitor the notification device information of the notification device on a periodic basis.

9. The system of claim 6, wherein the notification device information comprises trouble device issues.

10. The system of claim 1, wherein the wireless base unit is configured to send a tamper message when the notification device is unplugged from the wireless base unit.

11. The system of claim 1, wherein the notification command comprises activation information, deactivation information, sync protocol information, and/or battery load testing information of a load circuit on the notification device.

12. The system of claim 1, wherein the wireless base unit is a repeater having a master transceiver for wirelessly rebroadcasting the alert messages to another wireless base unit.

13. A monitoring and mass notification method, comprising:

plugging a notification device into a base interface of a wireless base unit;

the notification device sending notification device information to the wireless base unit indicating a type of the notification device; and

the wireless base unit reporting the notification device information to the control unit;

broadcasting alert messages from a control unit on addressable wireless links;

receiving the alert messages at a slave transceiver of the wireless base unit based on an identification address;

the wireless base unit sending the notification device a notification command; and

the notification device generating an alarm notification in response to receiving the notification command from the wireless base unit.

14. The method of claim 13, wherein the notification device is a horn, a strobe, or a speaker.

15. The method of claim 13, wherein the notification device is powered by a battery, an external power source, or an energy harvesting unit.

16. The method of claim 13, further comprising the wireless base unit receiving the notification device information for the notification device when the notification device is plugged into the wireless base unit.

17. The method of claim 16, further comprising the wireless base unit reporting the notification device information to an alarm panel via the control unit for programming the notification device.

18. The method of claim 16, further comprising the wireless base unit sending a notification status check to the notification device in order to monitor the notification device information of the notification device on a periodic basis.

19. The method of claim 13, further comprising the wireless base unit sending a tamper message when the notification device is unplugged from the wireless base unit.

20. A monitoring and mass notification system, comprising:

a control unit for broadcasting alert messages via addressable wireless links;

a wireless base unit having a notification interface, a slave transceiver for receiving the alert messages from the control unit, and an identification address for distinguishing the wireless base unit from other wireless base units; and

a notification device having a base interface for plugging into the notification interface of the wireless base unit;

wherein the wireless base unit is configured to receive notification device information for the notification device when the notification device is plugged into the wireless base unit; and

the wireless base unit is configured to report the notification device information to an alarm panel via the control unit for programming the notification device;

wherein the notification device receives a notification command from the wireless base unit and the notification device generates an alarm notification in response to receiving the notification command from the wireless base unit based on the broadcasted alert messages associated with the identification address.
