Abstract

"MéTODO E APARELHO PARA INDICAR ATIVAçãO DE UM ALARME DE DETECTOR DE FUMAçA". Trata-se de um método para detectar alarmes de detector de fumaça que compreende analisar pelo menos dois parâmetros de som ambiente durante um período de tempo para detectar um padrão temporal do alarme. Em uma modalidade, uma série de amostras são pegas durante um período de tempo suficientemente longo para incluir pelo menos um período total de um padrão de som que se repete e os dois parâmetros são freq³ência e amplitude do soma mais alto em cada amostra. A análise algorítmica pode ser ativada por um algoritmo de detecção que utiliza uma quantidade inferior de energia do que a análise algorítmica. Em outras modalidades, o aparelho de detecção é incorporado em um detector de fumaça convencional que irá detectar tanto fumaça como um alarme a partir de outro detector. Em outra modalidade, um detector de fumaça inclui um transreceptor para transmitir um sinal de ativação para detectores de fumaça adjacentes quando um incêndio é detectado e para receber um sinal de ativação a partir de detectores adjacentes.
