    Abstract: Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided. The dongle may be configured to alternate between drawing first and second amounts of power from the control panel system in response to the hazard detection device alternating between operating in a normal mode when no hazard is detected and an alarm mode when a hazard is detected. The hazard detection device may operate independently of any characteristics of the control panel system. For example, the hazard detection device may operate without drawing any power from the control panel system. Therefore, the dongle may allow for various types of hazard detection devices to interface with a common two-line power control system.
