Abstract

A two-way pager alarm system for a home or business that reports to a security monitoring center in a wireless fashion. The alarm system, when required, initiates communication with the security monitoring center through the existing base station network that supports the two-way pager'"'"'s communication, thereby transferring an alarm condition message to a distant security monitoring center with minimal transmission power. The message to the security monitoring center contains an individualized code which identifies the owner of the alarm system and also contains additional information, such as the alarm condition. The communication between the alarm system and the security monitoring center is based upon a two-way paging protocol such as ReFlex™. At the security monitoring center the message is received and translated by a computer into specific information pertaining to the alarm system. The two-way pager technology can be incorporated into new or existing alarm systems, and can replace and/or augment other alarm communication methods.

Claims

1. An alarm system which provides a two-way wireless communication link between a centralized sensing station and a remote security monitoring center, said alarm system comprising:

at least one sensor means for detecting an alarm condition event and providing an alarm condition signal;

a sensing center means for receiving and processing said alarm condition signal;

a wireless communication circuit means connected to said sensing center means for transmitting and receiving in real time alarm condition information over a two-way pager network utilizing two-way pager communication protocols wherein said wireless communication circuit means includes a logic unit connected to a read only memory (ROM) means and a random access memory (RAM) means, said ROM means storing communication protocol data and said RAM means storing an identification code unique to said alarm system, said logic unit reading said protocol data and said identification code and immediately forming a transmission message based upon said alarm condition information and said identification code to process a message and to initiate transmission;

a security monitoring center means for transmitting and receiving reported alarm condition information over the two-way pager network utilizing the two-way pager communication protocols said monitoring center replying or interrogating a specific cite using the same single bandwidth.

2. The alarm system of claim 1, wherein said wireless communication circuit means includes a modulator unit and a demodulator unit connected to said logic unit, said modulator unit modulating said transmission message for two-way pager network transmission in real time.

3. The alarm system of claim 1, wherein said logic unit includes a data port for transferring data to said wireless communication circuit before installation.

4. The alarm system of claim 1, wherein said security monitoring center means includes a computer for processing alarm condition signals and returning notification messages.
