Abstract: Security systems, such as in a home or other building, periodically transmit status data to a remote facility so that the remote facility is continuously informed of the security systems' status. A user interface device at one security system, or a web browser at a personal computer, can obtain information regarding, or provide commands to, one or more other security systems at remote locations by communicating with the remote facility. The remote facility also reports specified events, such as alarms, that occur at a security system to one or more other security systems. Other information, such as video and audio data from a security system, can also be provided to the remote facility for sharing with other security systems. An intercom feature can also be established via the remote facility.

Abstract: A safety light is activated by a wireless signal from a control panel in a home security system is response to detection of a fire by the system. The safety light alerts rescuers of rooms in a home in which children may be located. The light may be window, door or wall-mounted, and have a single, or dual opposing, backlit faces. The backlit face includes a logo and/or text that is quickly recognized by rescuers. For example, a logo of a firefighter carrying a baby may be used with the text “tot rescue”. The safety light may communicate status information to the control panel, such as a low battery condition or a tamper alert. A tamper alert switch detects tampering with the housing of the safety light or its installation. Additional safety lights provide ambient illumination and directional information to an exit.

Abstract: Security systems, such as in a home or other building, are interfaced with one another so that alarm messages and other information regarding a first security system are communicated to a second security system. In response, a user at the second system can send commands to the first system, such as for arming or disarming the first system. A user interface device at the second system includes an output component, such as a display screen, for displaying alarm messages from both the first and second systems. Other information, such as video and audio data from the first system, can also be provided at the second system. An input component, such as a keypad, allows the user to enter commands for controlling both the first and second systems. Communication between the security systems may be realized via an RF link, telephone link, and/or computer network.

A plurality of line cards are designed to serve and interface with the large number of telephone lines. The auto test diagnostic mode tests the operation of the central station receiver, and is programmed to automatically dial into each of the plurality of line cards and to send to each line card a number of preformatted test signals using standard reporting formats that are generated by the auto test diagnostic mode. The auto test diagnostic mode is preferably provided on a test line card that generates the preformatted test signals.
