The present invention advantageously provides a method and system that combines arming and disarming of a security system with activation and deactivation of call forwarding, enabling a single input by an authorized user to alter the state of the security system and to activate or deactivate call forwarding. Further, when changing the state of the security system, a user authorization component determines whether call forwarding should be activated. Hence, forwarding of calls is based on both user criteria and the state of the system. Additionally, the state of call forwarding can be changed by an authorized user via the security system.

Advanced call forwarding

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 &#x2153; 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 IBdriver, 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.

A security device including a control panel for transmitting a pre-defined cadence pattern to a siren device. The siren device takes the pre-defined cadence pattern as an input and outputs an audible voice message that corresponds to the pre-defined cadence pattern. The siren device is capable of recognizing the pre-defined cadence pattern that indicates a security system armed or disarmed command from a user interface device as well as a detected alarm signal of fire, burglary and carbon monoxide from a corresponding smoke, motion and carbon monoxide detector. These signals are transmitted from either the sensors or user interface means to the control panel and then, in turn, to the siren device.
