Save You Families Life.

Smoke Detectors are the most valuable asset to a home. This simple device can prevent the loss of personal possessions and can preserve life. Most fatal house fires occur at night when the family is sleeping. Toxic gasses are emitted as fires rage through homes, while the family sleeps soundly down the corridor. They wake to hear the sound of the smoke detector alerting them of a fire. The family has enough time to escape from the unforgiving clutches of a house fire. The scenario displayed does not always end in a happy way. In many cases there is no smoke alarm present and if there is it is not operational. The tenants of the dwelling have disconnected the smoke detectors, which must be installed by law, as they pose as an inconvenience.

False alarms would have to be the greatest problem associated with smoke detectors and because people are intrinsically lazy when it comes to smoke detectors, they will find and easy solution out. By removing the battery from the smoke alarm false alarms will not occur however neither will a real alarm. The Intelligent Smoke Detector (ISD) was designed to fore fill all the requirements of a life saving device and a few extra features. The ISD is designed to reduce the inconvenience of false alarms and to operate from 240Volts mains power. The ISD maybe switched off for selected periods of time and should a false alarm occur be readily muted. These extra features will hopefully reinstate the smoke detector into people daily lives.
