Residential fires kill and injure thousands of Americans and cause billions of dollars in property damage each year. More than 428,000 home fires occurred in 1996, which resulted in a residential fire every 74 seconds, according to the National Fire Protection Association (NFPA). By the mid 1980s, laws that required alarms in all new and existing residences existed in 38 states and thousands of municipalities. Systems wired throughout the house are expensive to install and provide only a general alert, while standard smoke alarms are not interconnected. This E-Team's Location Specific Alarm Relay (LSAR) system is designed to be installed in individual rooms, but has the ability to transmit data and can relate the location of smoke in the event of a fire. For example, the existence of smoke in the basement will be relayed to the second floor bedroom through a combined horn and voice alarm.
