Abstract

The proposed invention finds particular use in homes which do not have and/or in which the occupants cannot reach a telephone for phoning the police when an emergency condition exists, but which rely on neighbors, who do have telephones, observing the existence of an emergency condition and telephoning it in to the appropriate agency. The system includes an audio signal generator, either alone or packaged with a visual alarm, signal generator. Typically, the system includes a wall plate switch plate mounted on the interior of the dwelling with the system controls including a circuit board with a power supply, electronic delay and relay circuitry mounted in a convenient location. Alternately, a remote control unit can be used for alarm actuation. Under a potential alarm condition, such as when an unknown person comes to the door, the person within the dwelling can press a first SET switch which begins to time out a predetermined time delay or time interval. The person can then go to the door, and if there is no trouble, he can return and activate a RESET switch to prevent actuation of the alarm at the end of the delay period and return the system to it'"'"' s initial condition. If, however, an emergency condition exists, he can press an emergency switch button to immediately bypass or override the delay and actuate the audio-visual alarm enunciator.

Claims

1. An alarm system for protecting a dwelling comprising:

a source of electrical energy;

means for generating an audible alarm signal;

means for generating a visual alarm signal;

means for supplying said electrical energy to said signal-generating means;

manually-operable means located within a dwelling to be protected for generating a trigger signal;

relay means operatively coupling said source of electrical energy to said alarm signal-generating means, said relay means being normally open to disconnect said source of electrical energy from said alarm signal-generating means and being responsive to the generation of said trigger signal for closing to connect said source of electrical energy to said alarm signal-generating means for turning on both said audio and visual alarm signals;

said manually-operable means including a manually-operable switch panel operatively disposed on an interior surface of the dwelling;

said switch panel including a first manually-operable switching means for initiating a predetermined time delay;

means responsive to the expiration of said predetermined time delay for generating said trigger signal;

reset switch means for resetting said first switch means to its initial condition and resetting said predetermined time delay period to zero; and

an emergency switch means for immediately generating said trigger signal without waiting for said predetermined time delay to elapse;

said alarm signal-generating means including;

a means for operatively engaging an electrical receptacle;

means for supplying electrical energy thereto;

means for generating an audible signal, said audible signal-generating means including a housing being integral with said means for engaging an electrical receptacle;

said housing including an electrical light receptacle; and

illumination means adapted to be operatively received within said electric light receptacle of said housing for supplying said electrical energy to said illumination means, said illumination means further including a protective covering for operatively shielding said illumination means from breakage.

2. The alarm system of claim 1 wherein said means for generating alarm signals are operatively disposed on an out-of-the-way yet readily visible portion of the exterior of the dwelling.

3. The alarm system of claim 1 wherein said alarm signal-generating means is operatively mounted on the roof of said dwelling.

4. The alarm system of claim 1 wherein the alarm signal-generating means is operatively coupled to an upper portion of the exterior wall of the building substantially out of the reach of the potential intruder.

5. The alarm system of claim 1 wherein said manually-operable means further includes a remote control system including a remote control transmitter unit adapted to be at least one of carried by and positioned near the person occupying the dwelling, a remote receiver located proximate said alarm signal-generating means, said receiver being responsive to signals transmitted by said remote control transmitter unit for receiving said signals and generating said trigger signal in response thereto.

6. The alarm system of claim 1 further including protective means operably disposed over said emergency switching means to prevent the inadvertent actuation thereof, said protection means being manually positionable to expose said emergency switch means for operation thereof.

7. The alarm system of claim 1 further including flasher means adapted to be operatively disposed within said means for supplying electrical energy thereto for enabling at least one of said audible alarm means and said illumination means to be intermittently actuated to better attract the attention of neighbors thereto.

8. The alarm system of claim 1 wherein said protective covering includes an optically transmissive material.

9. The alarm system of claim 8 wherein said protective covering further includes means for readily transmitting sound therefrom.

10. The alarm system of claim 1 wherein said means for generating an audible alarm signal includes at least one of a siren, horn, bell, buzzer, warbler, an oscillating tone generator, and a whistle.

11. The alarm system of claim 1 wherein said means for generating a visual alarm signal includes at least one of a rotating police light, a strobe light, flashing lights, flashing colored lights, and alternating bi-colored flashing lights.

12. In an alarm system for a dwelling, said dwelling including electrical receptacle means on an exterior surface of said dwelling, an AC source of potential, an AC circuit coupled between said source of potential and said electrical receptacle means, and on-off switching means operatively disposed on an inner wall of said dwelling in said AC circuit for activating said exterior electrical receptacle means, an improved audio-visual alarm annunciator comprising:

audible alarm-generating means including an audible alarm housing, means operatively disposed within said housing for generating an audible alarm signal, and means for enabling the generated audible signal to be heard at relatively great distances therefrom, said audio alarm housing including an electrical connector means adapted to be readily connected to and removed from a conventional electrical receptacle on the exterior of said dwelling and a light socket operably disposed on an opposite surface thereof, an illumination means adapted to be operatively coupled to said light socket receptacle and a protective shield operatively covering said illumination means to prevent damage thereto.

13. The alarm system of claim 12 further including flasher means operatively insertable within the AC electrical circuit between said exterior electrical receptacle and said illumination means for intermittently operating at least one of said audible alarm signal-generating means and said illumination means.

14. The alarm system of claim 12 wherein said protective shield includes an optically transmissive material.

15. The alarm system of claim 14 wherein said protective shield further includes means for enabling sound to be emitted therefrom.
