TECHNICAL FIELD
The present novel technology relates generally to the field of electrical devices, and, more particularly, to a device for detecting alarm sounds and initiating a visual response.
BACKGROUND OF THE INVENTION
Most home alarm system sirens, whether alerting the homeowner to fire, break-in, intruders, or other emergencies, are located inside the home. The alarm, when sounded, is intended to alert the home's occupants to an emergency situation. The alarm is typically not intended to be heard outside the home. In the rare event that the alarm may be heard outside, it is not loud enough to be heard from the street or by the neighbors. Even if an emergency alarm is sounding inside the home, there is typically no way for anyone outside the house to become aware that there is anything wrong inside. Thus, neighbors and passersby are not early given the opportunity to provide aid and assistance as the emergency situation is first developing, at a time when many emergencies can be thwarted before a potential problem develops.
While there are some alarm systems that produce external lights or noises, these inevitably require dedicated lighting that must be installed on the exterior of the home. Such systems, while helpful, are expensive to purchase and install, require their own independent lighting fixtures, and mar the outward appearance of the home. Thus, there remains a need for alerting those outside the home that an emergency situation has arisen and has triggered an alarm that does not require additional dedicated lighting installation. The present novel technology addresses this need.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles of the novel technology and presenting its currently understood best mode of operation, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the novel technology is thereby intended, with such alterations and further modifications in the illustrated device and such further applications of the principles of the novel technology as illustrated therein being contemplated as would normally occur to one skilled in the art to which the novel technology relates.
As used herein, the phrase “transceiver” is typically a transmitting and receiving device, such as a two-way radio. But may also be solely a receiver or solely a transmitter.
As illustrated in FIGS. 1-5, the present novel technology relates to a system 10 for overriding a light switch in the on or off position to energize lights on that were previously turned off, as well as to control the lights to blink in a predetermined pattern, such as a Morse code SOS signal pattern.
In one embodiment, the system includes an switch circuit portion 15, a listening circuit portion 20, and, typically, a user interface portion/remote control portion 25, which may be part of the switch circuit portion 15 or the listening portion 20, or may be a separate and independent unit. The switch circuit portion 15 includes an electric circuit 30 connectable to a switch 35. The switch 35 may be a toggle switch, such as a standard on/off light switch, a photoelectric switch, or the like. In some embodiments, the switch circuit portion 15 is integrally connected to a switch 35; in other embodiments, the switch circuit portion 15 is separate but connectible to a switch 35. The switch circuit portion 15 includes a switching circuit 30 and a transceiver 40 operationally connected thereto for radio or wireless communication with the listening circuit portion 20.
The listening circuit portion 20 typically includes a housing 50 with a listening circuit 55 disposed therein. The listening circuit 55 is operationally connected to a microphone 60, and also is operationally connected to a transceiver 65 for radio or wireless communication with the switch transceiver 40.
The remote control portion 25 includes a user interface 70, a radio circuit 75 connected thereto, and a transceiver 80 for communicating with the switch circuit portion 15 and/or the listening circuit portion 20.
The switch circuit portion 15 and the listening circuit portion 25 may include internal power supplies 85, such as batteries, operationally connected thereto to provide power to the circuit, or, alternately, may be directly connected to the respective switch 35 and/or alarm device to draw power therefrom.
The switch circuit 30 is configured to, upon receipt of an initializing signal from the listening circuit portion 25, automatically override the switch 35 to energize and deenergize the connected load 90, typically exterior or interior lighting, in a predetermined pattern.
The listening circuit 55 monitors audio alarms, and is typically configured to respond to audio alarms playing at or above a consistent and predetermined volume by transmitting an enabling signal to the switching circuit 30. The listening circuit 55 may likewise be configured to respond to alarms of predetermined frequencies and/or patterns and/or the like. The user interface/remote control portion 25 may be used to configure the listening circuit 55 as desired.
A plurality of listening portions 20 may be positioned adjacent or close to respective alarm units positioned in different locations and/or for responding to different types of emergencies. Each listening portion 20 is configured to send an enabling signal to one or more switching portions 15 connected to a switch 35 controlling a respective light fixture or lighting system.
Once enabled by receipt of the enabling signal, the switching circuit 30 overrides the manual switch 35 to alternately energize the light load 90 to flash a predetermined pattern, such as a Morse code SOS or the like, to get the attention of neighbors and/or passersby to alert them to the emergency so that help may be summoned.

In operation, the switch portion 15 is operationally connected to an existing light switch 35 (toggle type, photocell, or the like) such that when the circuit 30 is not enabled by receipt of an enabling signal, the switch functions normally. One or more listening portions 20 are positioned to monitor the audio speaker elements of one or more emergency alarms, such as smoke detectors, burglar alarms, or the like. The listening portions 20 send an enabling signal to the switch portions 15 when they detect an audio signal meeting a predetermined set of criteria. Once enabled, the circuit 30 overrides and bypasses the switch 35 and sequentially energizes and deenergizes the lights normally controlled by the switch 35 in a predetermined distress or alert pattern. The distress pattern is typically enabled until the switch portion 15 receives a reset or cancellation signal input through the user interface 70. In some embodiments, the enabling signal may be manually sent from the remote control 25.
In other embodiments, the switch portion 15 is provided already connected to a switch 35 for original installation. In some embodiments, the switch portion 15 may be connected directly to a power source, such as a standard 120V AC electrical outlet. In other embodiments, the user interface 25 may include a low battery indicator, on/off switch, signal strength indicator, and an on/off length of time feature after a signal is detected, an emergency call button, and/or a test button. In other embodiments, the user interface 25 is part of a mobile telephone app. The emergency call feature, when actuated, may signal the switch portion 15 to override the lighting to flash the predetermined emergency sequence, and may also initiate a predetermined emergency message via the 911 emergency system or the like.
While the novel technology has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character. It is understood that the embodiments have been shown and described in the foregoing specification in satisfaction of the best mode and enablement requirements. It is understood that one of ordinary skill in the art could readily make a nigh-infinite number of insubstantial changes and modifications to the above-described embodiments and that it would be impractical to attempt to describe all such embodiment variations in the present specification. Accordingly, it is understood that all changes and modifications that come within the spirit of the novel technology are desired to be protected.
