In the embodiment, the user (not shown) speaks into the microphone device 90 a message that the user desires to be played if adverse conditions are detected by one of the detectors 103a-d. The control logic 86 stores the digital data indicative of the message as prerecorded message data 91. Further, the control logic 86, either automatically, periodically, or upon request by the user via the input device 82, transmits the prerecorded message data 91 to one or all of the detectors 103a-103d. 
FIG. 2 is a block diagram of an exemplary detector 103a of the present disclosure. Note that only 103a is described, however, the other detectors 103b-103d are configured identically.
As illustrated in FIG. 2, the detector 103a comprises one or more sensors configured to detect the presence of an adverse condition. The exemplary sensors in 103a include, but are not limited to, smoke/fire sensor 207, CO2 sensor 227, and CO sensor 225. Thus, the detector 103a is configured to detect smoke, fire, CO and CO2.
In one embodiment, the smoke/fire sensor 207 may comprise an optical sensor that is configured to detect any number of conditions, e.g., smoke, fire, presence of an individual, etc. The smoke/fire sensor 207 may comprise a potentiometric sensor (or ion sensor) that detects the presence of analytes in the air. The smoke/fire sensory 207 may perform air-sampling to detect analytes in the air. Also, the smoke/fire sensor may comprise an infrared sensor that may be used to detect flames. The afore-described sensors are merely examples of the types of sensors that may be used in the detector 103a. Any sensor technology hereafter developed suitable for sensing the presence of smoke or fire may be used in the detector 103a of the present disclosure.
The detector 103a may be powered by standard residential electricity supply (e.g., 120 VAC) 201. Additionally, the detector may comprise a rechargeable battery 203 in the event residential power fails. As depicted in the diagram, the battery 203 may be charged with the residential electricity supply 201.
Detector 103a also preferably comprises one or more visual and aural warning displays, for example, a speaker 233 through which the above-referenced voice messages are played, a buzzer 229, as well as a light display 231. In one embodiment, the light display 231 may comprise an arrow shape that points the way to egress from the building. Optionally, detector may comprise a microphone 235. So configured, any detector 103a-103d may be used as a two-way communication system, either detector-to-phone, or detector-to-detector, via the WAN 100 (FIG. 1A).
Detector 103a-103d preferably further comprises a computer-based processor system 205 which may be configured with a central processing unit (CPU) 215 connected to a communication bus 219, and a computer-readable memory 211, such as, without limitation, flash memory, read-only memory (ROM), or random access memory (RAM), and can also include a secondary memory. The memory 211 may comprises control logic 280.
Control logic 280 comprises instructions, which are executed by the processor system 205 to operate in a specific and predefined manner, as described below. Control logic 280 may be implemented as one or more modules. The modules may be configured to reside in the processor memory. The modules include, but are not limited to, software or hardware components that perform certain tasks. Thus, a module may include, by way of example, components, such as, software components, processes, functions, subroutines, procedures, attributes, class components, task components, object-oriented software components, segments of program code, drivers, firmware, micro-code, circuitry, data, and the like. Control logic 280 may be installed in the memory 211 using a computer interface coupled to the communication bus 219 which may be any suitable input/output device. The computer interface may also be configured to allow a user to vary the control logic 280, either according to pre-configured variations or customizable variations.
As will be appreciated by those skilled in the relevant art, the processor system 205 may be achieved with a specialized apparatus to perform the steps described herein by way of one or more dedicated processor systems 205 with hard-wired logic or programs stored in nonvolatile memory, such as, by way of example, read-only memory (ROM), for example, components such as ASICs, FPGAs, PCBs, microcontrollers, or multi-chip modules (MCMs).
The processor system 205 further comprises a mesh network radio frequency transceiver 217 coupled to an antenna 223. A mesh network is a network topology in which each node in the network relays data, cooperating to distribute such data. Wireless mesh networks may use any suitable wireless communications protocol, e.g., cellular, IEEE 802.11, IEEE 802.15, or the like. In one embodiment of the processor system 205, the network transceiver 217 is compatible with a wireless protocol particularly useful in local area network (LAN) applications, such as Wi-Fi® (802.11), or in personal area network (PAN) applications, such as BlueTooth® (802.15), Z-wave, wireless internet, etc. In addition, the processor system 205 may optionally comprise a frequency modulated (FM) radio receiver coupled to a compatible antenna. This allows a detector 103a to receive warnings through FM radio from EAS, providing a means to receive notifications in the event a smart phone 101 is not within the WAN 100.
Note that in one embodiment, the prerecorded message data 91 (FIG. 1B) is received by one or more detectors 103a-103b, and the control logic 280 stores the prerecorded message data 91 in memory 211. In the event that one of the sensors 207, 281, 227, or 225 detects an adverse condition, the control logic 208 may play the prerecorded message on the speaker 233 so that it is audible for those in the structure or building in which the detectors 103a-103d are installed.
FIG. 3A illustrates an exemplary housing 303 for a detector 103a-103d, a grid 301 of openings for aural messages to be emitted, and an arrow-shaped light display 231. In FIG. 3B, the arrow-shaped light 231 may include a projection lens that allows light from the arrow-shaped light 231 to be projected as an arrow shape image 302 on a floor 305 pointing in the direction toward safe egress.
FIG. 4 is a diagram of a user interface that is displayed by control logic 86 (FIG. 1B) to a display device 84. simply illustrates a smart phone, known in the art or hereafter developed, that is configured with control logic 86 (FIG. 1B) and that facilitates a user to control the system 98 (FIG. 1A).
In this regard, the control logic 86 displays a list of options to a user (not shown). In the exemplary user interface the user has the following options: “DETECTOR INTERFACE,” “RELAY EAS/WEA ALERT MESSAGES,” “USER-DEFINED ALERTS,” “DETECTOR STATUS,” and “SILENCE ALERT.”
When the detector interface selection is selected by the user, the control logic 86 displays options for testing the detectors 103a-103d. In this regard, the control logic 86 is configured to transmit data indicative of a status query to at least one of the detectors 103a-103d. In response, each of the detectors self-tests for operational errors, e.g., a dead battery or inoperative connection through the WAN 100 to one or more other detectors 103a-103d. 
When the relay eas/wea alert messages selection is selected by the user, the control logic 86 displays one or more options for forwarding alerts to the detectors 103a-103d. For example, there may be a tornado warning, and upon selection by the user, the control logic 86 transmits data indicative of the warning to the detectors 103a-103d. Upon receipt, the detectors 103a-103d are configured to initiate aural or visual alerts to alert occupants of the structure.
When the user-defined alerts selection is selected by the user, the control logic 86 provides a graphical user interface (GUI) that enables the user to define an alert that the control logic 86 transmits to the detectors 103a-103d. Upon definition, the user may elect to transmit data indicative of the user-defined alert to the detectors 103a-103d. 
When the silence alert selection is selected by the user, this indicates that the alert message previously sent to the detectors 103a-103d isn't or is no longer valid. In response, the detectors 103a-103d silence some or all the aural or visual alerts that were previously initiated.
FIG. 5A is a flowchart depicting exemplary functionality and architecture of the control logic 86 (FIG. 1B) of the smart device 101. In step 501, the control logic 86 is launched by the smart device 101, and the control logic 86 displays a home graphical user interface (not shown) that may include displaying the options hereinabove outlined. Note that in one embodiment, the control logic 86 may automatically launch in order to provide alerts to the user of the status of the warning system 98. In another embodiment, the user may click on an icon (not shown) to affirmatively launch the control logic 86.
Upon launching the control logic 86 in step 501, the control logic 86 may request user login credentials in step 502. Note that in one embodiment, the control logic 86 may be launched selection by a user (not shown) of an icon displayed on the smart device 101 (FIG. 1). However, in other embodiments, the control logic 86 may be launched in other ways. In response to the request for user login credentials, the user enters the appropriate information via the input device 82 (FIG. 1B).
Once activated, the control logic 86 automatically issues a system check query in step 503 to the detector 103a-103d (FIG. 1A) via the WAN 100 (FIG. 1A) or the cellular network 92 (FIG. 1A). Note that the system check query may be issued by the control logic 86 in the form of a message or data packet that is transmitted to one or more detectors 103a-103d. 
One or more of the detectors 103a-103d receive the status check query. In step 504, the one or more detectors 103a-103d respond either via the WAN 100 or the cellular network 92 by providing an indication of the status of the network in step 504. Additionally, in step 505 the one or more detectors transmit data indicative of the status of the detector 103a-103d in step 505. In step 506, the control logic 86 displays data indicative of the status of the WAN 100 and of each detector 103a-103 to the display device 84 (FIG. 1B).
FIG. 5B is a flowchart depicting architecture and functionality of the control logic 86 when data indicative of an emergency (“emergency message”) is received by the smart device 101 in step 807. Note that the emergency message may contain data indicative of the particular detector that is not operating appropriately or indicative of the network 100.
When an emergency message is received in step 507 through the WAN 100 and the cellular network 92 by the smart device 101, the control logic 86 is configured to launch automatically in step 508. The message is converted to from cellular network protocol to WAN protocol in step 509 then transmitted to the WAN 100 at step 509.
FIGS. 6A through 6C provide exemplary architecture and functionality of control logic 280 (FIG. 2) by the CPU 215 (FIG. 2) resident on the detectors 103a-103d. Periodically, any one detectors 103a-103d may initiate a network check in step 601 querying the other detectors 103a-103d. In response, the detectors 103a-103d answer the query 602 through the WAN 100. The control logic 280 transmits data indicative of the network health of other detectors 103a-103b in step 603. Additionally, the control logic 280 transmits the data indicative of a report status to the smart device 101.
Note that if a detector 103a-103d does not respond, the smart device 101 may flag the detector 103a-103d as inoperative. In one embodiment, each detector 103a-103d periodically executes a self-check in step 604 and automatically reports its status to the network at step 603. In this embodiment, the detectors 103a-103d transmits the data to the smart device 101 at step 605.
In the event an alert message is received by a detector 103a-103d via the smart device 101 in step 606, the detectors 103a-103d aurally and/or visually alert residents of the structure in step 607. Further, the data indicative of the alert message is transmitted to the other detectors 103a-103d in the WAN 100 in step 608. Similarly, if any detector 103a-103d detects fire, smoke, CO or CO2 in step 609, the detectors 103a-103d aurally and/or visually alert residents in the structure at step 610. Further, data indicative of the alert is transmitted to the WAN 100 in step 611. It should be noted that data indicative of the alert can also be transmitted to the smart device 101 via the WAN 100 and the cellular network 92.
