Abstract: The Modem Locator is specifically designed to be used in vacant properties, businesses or residential homes when no one is at home or at night when they are asleeep. The Modem Locator can be plugged into the wall and in the event that the locator detects smoke or heat it will automatically dial the fire department giving the owners address, and also his phone number. The Locator can also pre-record the test sound of already existing and installed smoke detectors. If the locator picks up the sound of the smoke detector it can then distinguish it and again will automatically call the fire department. The address and phone number will be prompted during set up installation instructions and recorded by the locator. It can then be played back to make certain it is clear and accurate. The fire department number will also be coded in either at the manufacturers or retail outlet or by the purchasers.    In the event that the owners are not in the house or building or are injured when a fire breaks out the Locator will automatically respond dialing the fire department via the modem. This will reduce the amount of time the fire will have to expand thus saving people from being hurt or killed.    A Locator would be ideal for commercial or residential use or for cabins or garages or storage facilities.    I would also design this system with the capacity to use batteries for portability as well as plug in adapters. Another item which I would install as an option would be a call forwarding system so that in the event no phone lines are available for the modem then via microwaves a system could be developed to call forward through to any phone lines within a given radius.    This would make it even more mobile and versatile. The Locator would have a sensitive sound system to pick up the beep of original smoke detectors if they went off within the Locators vicinity.    The Locator will also emit its own beep at a very loud tone like smoke detectors.    This system is well within our capabilities to build and would save countless lives if installed in hotels, high rises and old age homes.    It will also reduce the amount of property damage individuals will incur which would be a benefit to the owner and the insurance companies.    Finally, it will reduce the amount of time a fire has to expand thus reducing the risk to firefighters lives if they arrive even minutes earlier and they have to enter a burning building.   To prevent any false alarms from occuring the primary detectors would be placed on the ceiling like regular smoke detectors on each floor and in specific areas. The detectors would be designed to not only emit a warning beep but also to send an electromagnetic signal from the primary locator to the modem locator activating it. In the event that no one is in the building the fire department will still be called.  The locator will be designed to only go off when it absorbs sufficient smoke to ensure that there is a smoke danger building as outlined by government regulations and requirements.   This system would be a supplement to smoke detectors and because of there technological ingenuity will be purchased by many people and companies who might not purchase smoke detectors and would otherwise suffer potential losses.   A less expensive B model would be a modem with a built in smoke detector attached directly to the phone line. In this case you would only require one Modem Locator however it would not cover as great an area as the first option.
