A wall plate adapter for coupling home network control signals to AC power wiring, where the wall plate adapter includes built-in signaling circuitry. The wall plate adapter includes a plate with a receptacle face with slots that are aligned with slots of an underlying AC receptacle. When prongs of a plug are inserted into the slots of the wall plate adapter, they touch contacts that are located in the slots of the receptacle face. The contacts are, in turn, coupled to the signaling circuitry, which may be located in an enlarged region of the wall plate. The signaling circuitry is only coupled to the AC power when a plug is inserted. The plug may be coupled to a transformer and a network device.

A virtual receiver having multiple communication ports for connecting a link to a plurality of local security systems. The virtual receiver is programmed with a virtual receiver number and a virtual line number for each physical communication port on the receiver. The virtual receiver has a master/slave operational mode such that the data received from the plurality of local security systems by each receiver is transmitted from at least one selected slave receiver to a selected master receiver. The virtual receiver number and virtual line number is used to create a part of a subscriber number. In master/slave operation mode, M number of receivers are linked together and the possible number of virtual receiver lines in a virtual receiver is M times the number in a normal mode of operation.

A security central station monitors a plurality of individual subscriber security systems installed in residential or commercial accounts. Each security system at an account is programmed to periodically place a telephone call to the security central station receiver, and then to send a signal to the security central station receiver over the placed telephone call. The ten digit telephone number of the account is programmed into the security central station as the ten digit account number of record. When the signal sent by the security system is received by the security central station receiver, the security central station compares the ten digit caller telephone number with the ten digit account number of record. Normally, the ten digit caller telephone number will match the ten digit account number. However, a mismatch between the two ten digit numbers indicates to the security central station that the telephone number of the account premises protected by the security system has been changed, and alerts the security central station to investigate the matter further.

Line load compensation and reflection reduction in a signal transmitting circuit is provided using feedback capacitors. The feedback capacitor serially coupled with a resistance generates an RC rise/fall time that is independent of the line load. Additionally, by selecting a capacitor that yields a rise/fall time of approximately ⅓ of the maximum bit transmission time, signal reflection on the signal line can be reduced. Accordingly, by incorporating the feedback capacitor with a differential drive circuit, such as the IB 485 driver, variations in line load can be compensated for while also reducing signal reflection due to un-terminated or improperly terminated signal lines, thus allowing a free topology implementation.

The present invention relates to a method and system for automatically uploading the configuration of a security system to a central station automation system via telephonic lines, long-range radio (e.g., cellular), or Internet. The end result is that the automation system has sufficient information regarding the type and configuration of the system installed at the protected premises to properly handle alarms reports from that system.

A security system, such as in a home or other building, includes a broadcast band RF transmitter for transmitting an audio message that can be received by a user on a common home or car radio, for example. The audio message may be provided in response to a command that is transmitted to the security system by a user from a wireless key fob or the like. The user command may instruct the security system to arm or disarm itself, for instance. The audio message, which can be received on a selected channel on a car's radio receiver, informs the user that the command has been executed. The audio message may include a voice message such as “system armed” or“system disarmed”, a musical passage, a beep, chirp, or the like.
摘要:
A method is disclosed of automatically configuring security system control panels by using calling number information that is provided by a telephone call made to a specified telephone number, such as Calling Number Delivery (CND) information that is provided by a telephone call made to a toll free (800) telephone number. After an initial installation of a security system at an installation site, the security system control panel dials the specified telephone number to establish a telephone connection to a security company database center. The security company database center receives the calling number information that includes the telephone number of the installation site, and utilizes the telephone number of the installation site to look up in a database the security system control panel configuration information. This control panel configuration information is then automatically transferred and downloaded over the telephone connection to the security system control panel to configure and program the control panel for operation. The method of establishing a connection to a specified telephone number can also be utilized to reconfigure an already-installed security system, and also to configure many other devices and systems unrelated to security systems that need to be customized or configured.
摘要:
A system and method to assist the user of a wired phone that includes a security panel that includes means for connection to an associated phone line, a caller ID receiver and an RF transmitter. The caller ID receiver cooperates with the associated phone line and the RF transmitter cooperates with the caller ID receiver to transmit caller ID information. The system further includes a bracelet to be worn by an associated user that includes an RF receiver. The RF receiver cooperates with the RF transmitter to access information provided by the RF transmitter. The bracelet further includes a display cooperating with the RF receiver to indicate to the user information regarding an incoming call on the associated phone line.
摘要:
A system and a method for processing an incoming telephone call to an alarm system central monitoring station using call source identification data such as caller ID. The alarm system central monitoring station can use the caller ID information transmitted by the telephone company to make decisions as to how to process a call prior to the central monitoring station receiver answering the call. The central monitoring station will process the call by checking if the caller ID information matches caller ID information stored in memory and it will check status information associated with the caller ID information to determine if the call should be disconnected, transferred, or connected. In order to accomplish this the central monitoring station comprises receiving circuits for detecting an incoming telephone call on the telephone line and reading caller ID information associated with the call, switching circuits coupled to the receiving circuitry for transferring the call if necessary, memory for storing status information comprising the caller ID information, and processing circuitry for determining if caller ID information has been stored in the memory, and if it has, then accessing the status information and processing the call as a function of the status information. The central monitoring station may process the call by 1) transferring the call to an invalid alarm call station, 2) connecting the call to a central monitoring station receiver, a second central monitoring station receiver, or a second line of a central monitoring station receiver, or 3) disconnecting the call.
