Abstract

A smoke detector, a carbon monoxide detector, and a cellphone are combined into a single device in providing an alarm to a user upon the detection of smoke and/or carbon monoxide in a closed environment.

Claims

1. A mobile warning system comprising:

first means for detecting a smoke condition in a closed environment beyond a first predetermined threshold;

second means for detecting a carbon monoxide condition in a closed environment beyond a second predetermined threshold; and

a cellular phone incorporating said first and second means, programmed to provide at least one of a ringtone or voice alert upon detection by said first or second means of either or both of said thresholds being exceeded.

2. The mobile warning system of claim 1 wherein said cellular phone is programmed to a standby mode of operation.

3. The mobile warning system of claim 2 wherein said voice alert sounds a warning to immediately vacate from the closed environment.

4. The mobile warning system of claim 3 wherein said cellular phone is also programmed to alert a central monitoring station upon detection of either or both of said smoke or carbon monoxide threshold conditions being exceeded.

5. The mobile warning system of claim 4 wherein said cellular phone is additionally programmed to sound a warning to immediately vacate from the closed environment upon receipt of a radio communication from the central monitoring station that either or both of said smoke or carbon monoxide detection thresholds have been exceeded.

6. The mobile warning system of claim 5 wherein said cellular phone is further programmed to display a recommended travel path to vacate from the closed circuit environment upon receipt of the radio communication from the central monitoring station.
