Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     This device and integrated system relates to alarm warning devices in residential homes for the detection of smoke and associated elements of fire by emitting an audible alarm to warn the occupants and neighbors of the fire hazard or potential problems by activation of the device. 
     2. Description of Prior Art 
     Prior art devices of this type have been directed to a number of different smoke alarms; see for example U.S. Pat. Nos. 4,300,133, 4,788,530, 5,659,292, 5,745,040 and Patent Publications 2001/0038337 A1. 
     In U.S. Pat. No. 4,300,133, a smoke detector is disclosed having a modulation technique for smoke energy source and detector parameter changes to distinguish a fire source as opposed to a tobacco source. 
     U.S. Pat. No. 4,788,530 illustrates a remote switching device for smoke detection so upon a false alarm the user can activate a holding relay to disconnect the detector, stopping the alarm. 
     U.S. Pat. No. 5,659,292 claims an apparatus with a fire sensor and non-fire sensor such as a temperature and humidity device. This will provide an alert as to the potential of fire conditions to exist. 
     U.S. Pat. No. 5,745,040 shows an outdoor alerting device for smoke alarms in which an audible alarm and flashing light are activated on an outdoor location by an indoor smoke alarm by use of a microphone and amplifier for the audio outdoor speaker. 
     U.S. Patent Publication 2001/0038337 discloses a smoke alarm with time out feature using a remote transmitter activator and timer disabling the audio and visual alarm. 
     SUMMARY OF THE INVENTION 
     A smoke and fire alarm system providing for user selectable alarm activation delay and reset feature once the alarm has been initially activated. Interior and exterior structure alarms employ visual and audio alarm elements with integrated activation delay allowing the user to respond before the outside alarms to be activated. The alarm system provides an actuation interface with fuel supply cut-offs with multiple controls and command options for delay, reset or cancel the alarms prior post activated.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1  of the drawings, a fire alert warning system device  10  of the invention can be seen having a main control input panel  11  with an integrated programmable activation control circuit  12  indicated by broken inclusion lines thereabout. The activation control circuit  12  has a main power source P with a back-up battery  13  emergency power for activation when needed. The system  10  provides multiple fire detection sensors  14  as illustrated in the primary preferred embodiment has a smoke detector  15 A and  15 B, a fire detector (ionization sensing)  16 A and a heat sensor detector  16 B. This will provide the system  10  with multiple modes of detection and alert fire source application. The command and control circuit  12  is in communication with the detection sensors  14  and multiple system alarm components  17  positioned on the outside of the structure S indicated by perimeter broken lines as seen in  FIG. 1  of the drawings. 
     The alarm components  17  are comprised of both audio output device  18  such as a speaker and a visual illumination device  19  such as a strobe light. An interior audible alarm  20  of the detection sensors  14  and indicator light  21  on the control panel inside the structure as will be disclosed in detail hereinafter to confirm the system activation for the user during an alert. 
     The interior alarm indicator  21  of the alarm circuit  12  is activated when smoke, heat or fire is detected by the respective sensors  15 A,  15 B,  16 A and  16 B and will then initiate a pre-programmed alarm activation count down delay time T before the outside alarms  18  and  19  are activated. The countdown delay T is indicated on the main control panel  11  in LCD display  24 . 
     The effective time delay T “countdown timer” can be user programmed as illustrated in  FIG. 2  of the drawings as in this example from fifteen seconds to up to forty-five seconds for effective activation delay. This is achieved by fixed pre-programmed time delay input selection buttons  23 A,  23 B, and  23 C or alternately as a sequential selection indicated by a visual time indicator in the LCD display  24  in the control panel  11  as will be understood by those skilled in the art. 
     A primary user activation delay recess button  25  on the control panel  11  will preferably be larger than the other control access user inputs and in this example illuminated with a flashing sequence to help draw the user&#39;s attention thereto. 
     The reset button  25  is central to the primary mission of the alarm control system  10  of the invention since by activation it will cancel the outside alarms  18  and  19  before activation as hereinbefore described. As noted, the select user activation sequence of the system  10  can thus be reset if activation inadvertently occurs by extraneous smoke or heat sources such as cooking, for example. 
     Additionally, a portable hand held emergency remote control device  26  is provided shown in  FIG. 1  of the drawings which can be carried by the user and provides by digitally encoded command transmission to a receiver  26 A activation access to the central controller  11  for system operational access for emergencies such as medical accident, for example. 
     The fire alert warning system  10  of the invention has additional activation circuit elements indicated generally at  27  for additional multiple detection sensors  14  as may be required in different operational venue parameters beyond that of the primary sensors described. Additionally an emergency gas shut-off valve  28  which, in this example, is controlled by a direct circuit interface and relay in response to direct control input, as noted. A sound source (fire/smoke detectors when activated) will signal the control panel  11  which will in turn after program delay time has expired activate the outside audible and light alarms  18  and  19 . A switching element  29  may also trip the gas shut-off valve  28  upon detection of the outside audible alarm as hereinbefore described and understood by those skilled in the art. 
     The system  10  of the invention may be fitted with heat resistant wires within the structure and emergency control panel lighting upon activation in the event that power is not available through its primary power source and the system must rely on the back-up battery  13  as hereinbefore described. 
     Secondary user control activation is provided allowing for independent activation for non-fire related emergencies, such as health emergencies wherein the outside alarm elements  17  can be activated by the user by the remote control emergency device transmitter  26  which will alert the neighbors for help. The control panel  11  also has a number of system control input buttons beyond the primary flashing reset button  25  and delay timing buttons  23 A,  23 B and  23 C. In this example, an “away” activation button  31  would provide an instance outside alarm  17  activation upon fire detection sensor initiation with a slow beeping tone for alerting the user upon return that an event has occurred and that the system needs to be reset, also viewable in the LCD display screen  24 . Additionally, a large sleep button  32  is provided which is preferably green in color with interior illumination. Once selected, the sleep button would stay illuminated so as to be visible upon awakening with a “need to program” message in the LCD controller panel display  24  reminding the user that the operational system needs to be addressed before proceeding with the activities of the day. 
     It will thus be seen that a new and novel fire alert warning and delay system device  10  of the invention has been illustrated and described and that the system will provide the user while within the structure to effectively deactivate the alarm once initiated by the input of a pre-programmed time delay before the primary outside alarms  17  are activated. This control basis panel  11  institutes a number of different sequential alarm sequence action including an away button, sleep button, independent pre-programmed time delay alarm as well as auxiliary lighting, automatic source ignition shut-off valves, all within the parameters of a single independent inclusive alarm system which provides the user additional security and control. 
     It will be apparent to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
