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.
A dongle for interfacing a control panel system with a hazard detection device, the control panel system comprising a control panel and at least one wired detection string, wherein the control panel monitors a current level provided to each wired detection string to determine whether an alarm condition exists on the at least one wired detection string, and wherein the hazard detection device would cause a false alarm condition to exist for the wired detection string if it were directly electrically coupled to that wired detection string, the dongle comprising:

This disclosure relates to systems and methods for interfacing a hazard detection device with a control panel system and, more particularly, to systems and methods for interfacing a hazard detection device with a control panel system via a dongle.
Hazard safety systems, which may include one or more hazard detection devices (e.g., smoke detectors, carbon monoxide detectors, motion detectors, etc.) electrically coupled to a control panel via one or more wires of a control panel system, can be used in residential, commercial, and industrial settings to detect and warn of hazardous conditions for safety considerations. Sometimes, such control panel systems may be referred to as security panel systems or central panel systems. One known control panel system may be configured to be interfaced with each hazard detection device of a hazard safety system in such a way that each hazard detection device is powered by power provided over the wires of the control panel system from the control panel, and may further be configured to be interfaced with each hazard detection device in such a way that the hazard detection device pulls more power from the control panel system when the device changes from a normal mode of operation to an alarm mode of operation in response to detecting a hazardous condition. This increase in power drawn by the hazard detection device alerts the control panel of the control panel system that a hazardous condition exists in the hazard safety system.
As hazard detection devices advance to perform features in addition to sensing for hazards (e.g., to wirelessly communicate with remote devices), additional demands for power are needed by the advanced hazard detection devices. Issues may arise in the interfacing of such advanced hazard detection devices with control panel systems such as those described above in which increased power draw serves as an alerting mechanism. In particular, issues may arise in that an increased power draw by an advanced hazard detection device may be incorrectly interpreted by the control panel as an existing hazardous condition. Other issues arise as would be apparent to a person skilled in the art in view of the instant disclosure.
The above and other aspects of the disclosure, its nature, and various features will become more apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
FIG. 1 is a diagram of an enclosure equipped with a hazard safety system, according to some embodiments;
FIG. 2 is a schematic view of a portion of the hazard safety system of FIG. 1, according to some embodiments:
In the following detailed description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the various embodiments. Those of ordinary skill in the art will realize that these various embodiments are illustrative only and are not intended to be limiting in any way. Other embodiments will readily suggest themselves to such skilled persons having the benefit of this disclosure.
In addition, for clarity purposes, not all of the routine features of the embodiments described herein are shown or described. One of ordinary skill in the art would readily appreciate that in the development of any such actual embodiment, numerous embodiment-specific decisions may be required to achieve specific design objectives. These design objectives will vary from one embodiment to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would nevertheless be a routine engineering undertaking for those of ordinary skill in the art having the benefit of this disclosure.
Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided and described with reference to FIGS. 1-5.
