Abstract

A system and method for monitoring a premise in case of an emergency and enabling 2-way voice communications with an individual at every possible location within the monitored premises. The system utilizes a radio frequency 2-way wireless communication link from a centrally located Base Alarm Control Unit on the premise to plurality of Remote Alarm Control Units situated throughout the premise. Remote Alarm Control Units relay the information received from the wireless remote transmitters to the Base Alarm Control Unit thereby increasing the effective useful range of the wireless communication link. The same also establishes a 2-way voice connection between the Central Station operator and the individual who may be located at any possible location within the premise, thereby providing a much more effective handling of the emergency or alarm situation.

Claims

1. Alarm system for providing audio communications between a monitored location and a central monitoring station, comprising:

a. a first control unit having a radio transceiver, a speaker connected to a D/A converter, a microphone connected to an A/D converter, and a communicator for communicating with a central monitoring station;

b. a second control unit having a radio transceiver, a speaker connected to a D/A converter, a microphone connected to a A/D converter, and a communicator for communicating with a central monitoring station;

c. wherein, upon connecting the communicator of one of the first or second control unit to said central monitoring system, the connected first or second control unit functions as a base alarm control unit (BACU) and the non-connected first or second control unit functions as a remote alarm control unit (RACU);

d. wherein, said RACU utilizes said A/D converter for converting audio received by said microphone into a first digital signal and transmits via said radio transceiver said first digital signal to said radio transceiver of said BACU; and

e. wherein, said BACU transmits via said radio transceiver a second digital signal, and said RACU receives said second digital signal with said radio transceiver of said RACU and said RACU utilizes said D/A converter for converting said second digital signal into an analog audio signal which is converted by said speaker into audible sound.

2. The alarm system of claim 1, further comprising:

a. remote initiating device (RID) having a transmitter which transmits status information; and

b. wherein said RACU includes a receiver for receiving said status information from said RID and includes said status information in said first digital signal.

3. The alarm system of claim 1 wherein said first digital signal and said second digital signal are IEEE 802.15.4 compliant.

4. The alarm system of claim 1 wherein said communicator of said BACU communicates over a PSTN network to the central monitoring station.

5. The alarm system of claim 4 wherein said BACU further comprises a second D/A converter for converting said first digital signal to an analog signal to be transmitted over the PSTN network.

6. An alarm system of claim 1, further comprising a third control unit having a radio transceiver, wherein said radio transceiver receives said first digital signal and retransmits said first digital signal.
