Definitions
- the invention pertains to fire alarm systems. More particularly, the invention pertains to apparatus and methods of locating fire extinguishers in the event of a fire.
- Background for the Invention During the occurrence of a fire, the occupants of the involved dwelling may need to quickly access a fire extinguisher to extinguish the fire. The occupants may not know or remember the location of an available fire extinguisher, particularly in an emotionally stressful situation with an alarming smoke or fire detector and the presence of smoke and flames.
- an audible location identifier a distinctive audible alarm or recorded verbal location identifier
- US Patent No. 5,153,567 (Expired) describes a hardwired system whereby a fire extinguisher housing contains a smoke alarm and flashing light.
- Other related prior art known to the inventor is the US Patent Number 5 ,587,705 solely owned by the present inventor, and which describes radio frequency links between environmental condition detectors and remote, emergency lighting systems.
- 5,793,280 describes a beacon that is located on a fire extinguisher bracket such that the beacon is activated by the presence of motion in close proximity to the bracket.
- the invention described herein is a fire safety system whereby the occupants of a building are immediately notified of the location of fire extinguishers in close proximity.
- An audible alarm or verbal location identifier is activated by a remotely located, displaced, environmental condition detector (smoke detector, fire detector or heat detector).
- a fire detector is wirelessly coupled to a local extinguisher.
- the detector senses an environmental condition such as smoke, fire, or heat it sounds its conventional audible alarm and also sends a signal to cause a remotely located fire extinguished s) to sound an audible alarm or verbal location identifier (for example a verbal "Fire Extinguisher") or both.
- Occupants can as a result, quickly locate the fire extinguisher.
- the communication link between the detector and the remotely located fire extinguished s can be wireless (radio frequency, audio frequency or infrared).
- the link can be hardwired. In yet another embodiment, both types of links can be used.
- the audible tone/voice emitter electronic circuitry located at the fire extinguisher may be mounted directly to the fire extinguisher or the mounting hardware for the extinguisher.
- the circuitry may be positioned adjacent to the extinguisher.
- a battery-powered light may be included along with the local alarm or verbal location identifier to facilitate finding the fire extinguisher in the dark.
- the battery powered light component activates along with the fire extinguisher alarm locator and/or verbal location identifier.
- the wireless communication receiver located on the fire extinguisher or mounting hardware can be battery operated to afford portability or may be 120V AC powered in another embodiment.
- the detector, a smoke, flame or heat detector can be battery powered or powered by 120 VAC. The detector need only have the capability to detect one environmental condition (smoke or fire or excessive heat) within an adjacent region.
- FIG. 1 is an overall view of an extinguisher locator system in accordance with the present invention .
- Fig. 2 is a more detailed drawing of the extinguisher locator system of Fig. 1. Detailed Description of the Preferred Embodiment
- a system 10 includes an environmental condition detector (smoke detector, fire detector or heat detector, as separate embodiments) 14 and a fire extinguisher 16.
- An output unit 18 can be attached to or associated with extinguisher 16.
- the detector 14 includes a smoke, fire, or heat detection module 20, a wireless transmitter 22, and a power supply 24.
- the detection module 20 Upon detection of smoke, fire, or heat in the immediate area, the detection module 20 sounds its included audible alarm and activates the wireless transmitter 22.
- a wireless signal (radio frequency, audio frequency or optical) S is transmitted from the detector 14.
- the detector power supply 24 includes battery(s) and/or 120 VAC power as are well known in the art.
- the fire extinguisher receiver module 18 receives, decodes, and validates the wireless signal S. Upon validation of a transmitted wireless signal S, the receiver module 18 activates an audible alarm and/or a periodic audible verbal location circuit 30.
- the circuit 30 includes stored digital phrases, such as "Fire Extinguisher”.
- circuit 30 When circuit 30 is activated, a stored phrase such as "Fire Extinguisher" is audibly stated such that the location of fire extinguisher unit 16 may be quickly identified.
- a lamp 32 can optionally be included and illuminated to further assist in the location of the fire extinguisher unit 16, especially in a dark environment.
- the wireless signal S is transmitted for the duration of the environmental condition detected by the detector module 20.
- the fire extinguisher receiver unit 18, and all of its electrical components can be battery operated. This provides flexibility in locating the fire extinguisher unit 18. Alternately, unit 18 may be 120 VAC powered with or without battery backup.
- Unit 18 can be attached to extinguisher 16. Alternately, unit 18 can be placed on the floor or wall adjacent to extinguisher 16. In an alternate embodiment, detector 14 and extinguisher 18 can be hardwired to one another. In yet another embodiment, detector 14 can wirelessly transmit to a plug- in module 40, illustrated in phantom. Module 40 can in turn be coupled to unit 18 using a wired medium, for example the local electrical wiring.
