FIELD OF THE INVENTION
RELATED APPLICATIONS
[0001] This application is related to United States Patent Application No.
16/425,151, titled SYSTEM AND METHOD TO IMPROVE EMERGENCY RESPONSE TIME, filed on May 29, 2019.
FIELD OF THE INVENTION
[0002] Aspects of the present invention generally relate to fire detection and/or notification systems for buildings and, more particularly, a fire detection/notification system and method for detecting and responding to emergencies and other related incidents within a building environment.
BACKGROUND
BACKGROUND
[0003] In the event of any emergency, response time is critical. Emergency response time is especially important for systems that detect weapons discharge, such as gunshot detection, because the majority of shooting events end within 12 minutes. Delays in notifying emergency responders may have a substantial impact on the victims of the events. Thus, emergency response time must be minimized in order to save lives, and building occupants must be notified as quickly as possible.
[0004] Generally, fire detection and/or notification systems provide fire-related monitoring and protection services for a building. Modern fire detection/notification systems may be automated and include various components distributed throughout the building for detecting fire-related hazards, such as fire, smoke, or combustion, and alerting occupants of the building.
Components of the fire detection/notification system may include heat detectors, smoke detectors, CO
detectors, CO2 detectors, motion detectors, alarms, sirens, annunciators, power supplies, displays, monitors, Date Recue/Date Received 2023-03-01 control panels, air samplers, extinguishers, valves, actuators, call switches and/or other devices used for detecting hazards within the building. The system may report a hazard by sounding an alarm and/or notifying a fire detection/notification agent, such as a local fire detection/notification organization and/or trigger an appropriate corrective action, such as activating an extinguishing system.
Components of the fire detection/notification system may include heat detectors, smoke detectors, CO
detectors, CO2 detectors, motion detectors, alarms, sirens, annunciators, power supplies, displays, monitors, Date Recue/Date Received 2023-03-01 control panels, air samplers, extinguishers, valves, actuators, call switches and/or other devices used for detecting hazards within the building. The system may report a hazard by sounding an alarm and/or notifying a fire detection/notification agent, such as a local fire detection/notification organization and/or trigger an appropriate corrective action, such as activating an extinguishing system.
[0005] A security system may be integrated with the fire detection/notification system to provide security-related services for the building, in addition to the fire-related services. The security system may include components different from the fire detection/notification system to provide access control, intrusion detection, and video surveillance of selected areas of the building. Even so, the security system is similar to the fire detection/notification system in that the security system may report a hazard by sounding an alarm and/or notifying a security agent, such as a home security service. Since the security system reports the hazard in a manner similar to the fire detection/notification system, the integration of the security system with the fire detection/notification system results in operational synergies and efficiencies. On the other hand, the integration of the two systems is challenging due to the differences between the systems, i.e., detection of fire-related hazards vs. detection of security-related hazards.
[0006] Existing systems for detecting weapons discharge do not integrate well with fire detection/notification systems. Most buildings already have some form of fire detection/notification system and, for those buildings that do not include any type of system, an existing fire detection/notification system may be easily installed efficiently and economically. There may be an undue financial and timing burden in installing a second system to detect other emergencies, such as a weapons discharge detecting system.
SUMMARY
SUMMARY
[0007] Briefly described, a fire detection and/or notification system of a commercial or residential facility may be enhanced to detect other emergencies, such as detecting a weapons discharge. The fire detection/notification system and method combine fire detection/notification with weapons Date Recue/Date Received 2023-03-01 discharge protection. The fire detection/notification system and method may also provide services for other emergency indicators such as break-ins, occupant falling and calling for help, water left running, vehicle starting in garage/lot (indicating theft), and other acoustic abnormalities. The fire detection/notification and the weapons discharge system may share common functions such as, but not limited to, common circuitry for communicating with emergency responders.
These functions of fire detection/notification and weapons discharge are combined in a single fire detection/notification system to provide greater visibility and ease of use as well as to minimize costs and implementation time.

[0018] To facilitate an understanding of embodiments, principles, and features of the present invention, they are explained hereinafter with reference to implementation in illustrative embodiments. In particular, they are described in the context of a weapons discharge detection system integrated with a fire detection and/or notification system.
Embodiments of the present invention, however, are not limited to use in the described devices or methods.
Embodiments of the present invention, however, are not limited to use in the described devices or methods.
[0019] The components and materials described hereinafter as making up the various embodiments are intended to be illustrative and not restrictive. Many suitable components and materials that would perform the same or a similar function as the materials described herein are intended to be embraced within the scope of embodiments of the present invention.
[0020] The fire detection and/or notification system (also known as fire detection/notification system and fire alatin system) and method described herein combines fire detection/notification with one or more other emergency related features, such as weapons discharge protection. Since fire detection/notification systems are common and readily available, some embodiments of the system and method are directed to a fire detection/notification system including, or retrofitting existing systems with, weapons discharge detection features and utilize existing functions of fire detection/notification systems. For example, fire detection/notification systems may already include fire-related sensors, such as smoke detectors, so a fire detection/notification system may include audio sensors and a weapons discharge detection circuit to integrate weapons discharge protection feature. Also, the system may further include additional sensors, such as infrared ("IR") sensors, thermal sensors, pressure/shock sensors, fiber optics sensors, or additional audio sensors, to reduce false positives and/or false negatives. Thus, the fire detection/notification system is an enhancement of existing systems, which may include smoke detectors, duct detectors, pull stations, horn/speaker strobes, and the like, by including the additional features of detecting weapons discharge, alerting occupants of the discharge, and notify emergency responders. For some embodiments, the fire detection/notification portion of the system and the weapons discharge portion of the system may share common functions, such as a common output circuit for communicating with emergency Date Recue/Date Received 2023-03-01 responders, and the use of the one fire detection/notification system for these functions provides greater visibility and ease of use than separate systems. In addition, integration of weapons detection with existing systems may minimize costs and implementation time. Further advantages of the fire detection/notification system described herein may be realized via service upgrades, product updates, and migrations as well as test and inspection opportunities.
[0021] In addition, some embodiments of the fire detection/notification system and method may include, or retrofit existing systems with, wireless mesh networks. In particular, wireless devices may be positioned throughout a commercial or residential facility and communicate with each other to form the wireless mesh network. Each wireless device may transmit information associated with itself and serve as a relay for other wireless devices of the wireless mesh network, as well as the remainder of the fire detection/notification system. Since each wireless device utilizes the wireless mesh network, the wireless device may be positioned anywhere within a facility where a wired, wireless, or portable power source is available.
[0022] The fire detection/notification system, particularly the weapons discharge feature, may detect various types of threats or safety issues such as, but not limited to, glass breakage, forced portal entries, accident detection, calls for assistance, extended operation of short duration appliances, initiation of vehicles at unusual times or locations, acoustic detection of emergency events (such as fire and explosions), and the like. The weapons discharge feature of the fire detection/notification system may further collect other information that may be useful for evaluating threats or safety issues such as, but not limited to, machine failures (e.g., unexpected noise), occupancy of the facility, or other abnormalities at the facility.
[0023] The fire detection/notification system can eventually also integrate with other systems of the building management system, such as access control, surveillance and building automation. The fire detection/notification system operates in conjunction with one or more other systems to create a response from the facility, such as closing and potentially locking doors in areas that do not contain the threat. The fire detection/notification system may also be accessible to facility occupants for improved situation awareness and simplified mass notification in order to save lives.

[0024] The fire detection/notification system and method described herein combines fire detection/notification with weapons discharge protection. In particular, the fire detection/notification system performs the function of multiple systems by combining a system of fire detection/notification and mass notification with a weapons discharge detection system. For some embodiments, the fire detection/notification system allows for leveraging some components of existing infrastructure, such as alert notification devices and circuitry for communicating with emergency responders, without the need for separate systems for fire detection/notification and weapons discharge detection.
[0025] Referring to FIG. 1, there is shown a fire detection/notification system 100 for detecting a weapons discharge. The fire detection/notification system 100 includes a communication bus 102 to facilitate communications among various components, such as a control panel 104 and a management device 106. The control panel 104 is a device that identifies a fire-related hazards based on data received from fire-related input devices and manages fire-related output devices based on the identified fire-related hazard. As explained in detail below, the control panel 104 also identifies the weapons discharge based on data generated by weapons discharge sensors and manages weapons discharge output devices based on the identified weapons discharge hazard. The management device 106, such as a workstation and/or server, sets and/or changes the functions of the various components communicating via the communication bus 102, such as control panel 104.
[0026] The other components, such as outside device 108, may communicate indirectly with components of the fire detection/notification system 100 via a communication network 110.
Examples of the outside devices include, but are not limited to, remote terminals for receiving, provide, or exchanging data as well as other building management systems for controlling comfort functions, such as temperature, humidity, ventilation, lighting, security, and the like. Other examples of outside devices include, but are not limited to, building functions such as alerts, alarms, door opening/closing, and the like. While a brief description of the fire detection/notification system 100 is provided below, it is to be understood that the fire detection/notification system described herein is only one example of a particular form or configuration for the fire detection/notification system and the system may be implemented in any other suitable manner without departing from the scope of this disclosure.

Date Recue/Date Received 2023-03-01
[0027] For the embodiment represented by FIG. 1, the fire detection/notification system 100 provides connectivity to subsystems for various fire safety parameters. For example, control panel 104 may be communicating via wired or wireless link with various advanced devices 112 or basic devices, such as Notification Appliance Circuit ("NAC") devices 114 and other basic devices 116, for monitoring and controlling fire detection/notification for areas within a commercial or residential facility or a group of facilities. Examples of advanced devices include, but are not limited to, smart detectors 118, conventional detectors 120, air duct devices 122, input/output modules 124, and pull stations 126. NAC devices 114 notify occupants of a facility about a fire or other life-threatening emergency. The NAC is a physical wire loop that provides power to NAC devices 114, so the NAC
supervises the wires that make up the circuit as opposed to the devices themselves. The circuit extends from the control panel 104 to the NAC devices 114 located within the facility as connected by the physical wire loop. Examples of the notification appliances includes, but are not limited to, strobes 128, horns 130, chimes, bells 132, klaxons, and speakers. Other basic devices 116 are similar to the NAC devices 114 but require more management than mere power control, such as speakers that require audio signals for providing dynamic sounds and announcements. It is to be understood that the fire detection/notification system 100 may comprise any suitable number of any of components 112-138 based on particular configurations for each facility or group of facilities.

[0028] The fire detection/notification system 100 further includes devices and components for integration of weapons discharge features. In particular, the advanced devices 112 may include wired or wireless devices having fire-related detection sensors and weapons discharge sensors and the control panel 104 may include one or more weapons discharge circuits to communicate with the wired or wireless devices, respond by managing other devices and components of the fire detection/notification system, and communicate with an emergency responder device external to the fire detection/notification system.
[0029] The fire detection/notification system 100 may include security to protect communications among devices and components as well as communications with outside devices.
For example, the communications may be encrypted, and each device may be identified by signed credentials. The security may facilitate prevention of spoofing of signals by a perpetrator and suppression of detection of events or eavesdropping on signals by the perpetrator.

[0030] Referring to FIG. 2, there is shown another fire detection/notification system for detecting a weapons discharge. The fire detection/notification system includes a network 202, a control panel 204, and an output device 206. Examples of networks 202 include wired networks, wireless mesh networks, or a combination of wired and wireless networks). The network 202 includes multiple wired or wireless devices 208 having capabilities for communication with each other via wired or wireless intra-network links 210. Examples of devices 208 include, but are not limited to, weapons discharge detection devices and smoke detection devices. The wireless communications may include multi-band wireless communication to hinder an external party, such as a perpetrator, from blocking frequencies and to offer greater resilience to outside interference. Each device 208 may include a wireless communication module configured to communicate via the network. 202.
Examples of the wireless communication capabilities include, but are not limited to, satellite-based communications, cellular-based communications and their variants, and wireless local area network (WLAN) communication and their variants. Examples of WLAN communications include, but are not limited to, IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), Bluetoothmi, BLE, and ZigBeeTm.
Wireless communications may further include other forms of communication such as microwave or infrared technology (IR). One or more of the devices may also utilize, in addition to or in the alternative, wired technology for communication, such as transmission of data over a physical conduit, e.g., an electrical cable or optical fiber cable. Each device 208 transmits information detected by one or more of its sensors and serves as a relay for other devices of the network 202. If any device fails to function, the network is not compromised; the network will continue to function irrespective of the non-working device or devices.

[0031] Each device 208 also requires a power source for enabling sensor operation, wireless communication (and wired communication, if applicable), and other functions of the device. The power source for each device 208 may be a wired electrical connection, a wireless power transfer ("WPT"), or a portable connection (such as a battery).
[0032] Each device 208 further includes wired or wireless communication capabilities, via the wired or wireless communication module or another component of the device, for communication via inter-device links 212 with the control panel 204. The examples of communication capabilities for Date Recue/Date Received 2023-03-01 intra-network links 210, described above, may also apply for communications via the inter-device links 212 with the control panel 204.

Examples of inputs to the control panel 204 include, but are not limited to, a smoke detector input 214, a pull input 216, a heat input 218, and a tamper input 220. The inputs 214-220 received by the control panel 204 may be processed by various components of the control panel. For example, the control panel 204 includes one or more line cards or module cards 222 that process the inputs 214-220 by themselves or in conjunction with other circuits of the control panel.
[0034] The control panel 204 may include a module card 222 configured to receive input relating to the weapons discharge.

[0036] For some embodiments, processing of a weapons discharge hazard may be performed, in part or entirely, at a device of the network of devices. In addition to the control panel 204, processing may be executed at the detection unit; at the smart base; at the detection unit and the smart base; at the detection unit and the control panel; at the smart base and the control panel; or at the detection unit, the smart base, and the control panel.
