Abstract

APERFEIçOAMENTO INTRODUZIDO EM DISPOSITIVO PARA DETECçãO DE FUMAçA UTILIZADO COMO COMPONENTE DE SISTEMAS DE SEGURANçA E PREVENçãO CONTRA INCêNDIOS, o qual é caracterizado pelo fato de compreender uma base (1), um transmissor de infravermelho luminoso (2) configurado como um LED, um receptor infravermelho (3), também configurado como um LED, um disco bloqueador de luz (4), uma tela tubular (5), e uma tampa (6); a base (1) apresenta uma parede contornante (7) que atua como meio delimitador do espaço interno (8), no interior do qual ocorrerá a detecção da fumaça; a parede interna (9) da base (1) incorpora dois suportes de montagem (10), sendo um destinado a receber a montagem do transmissor (2) e outro destinado a receber a montagem do receptor (3); a mesma parede interna (9) da base (1) incorpora um par de anteparos angulares (12), que atuam de modo a delimitar, de forma exata, o campo de emissão de transmissão de infravermelho (2) e de recepção de infravermelho (3), impedindo assim a percepção indevida de um pelo outro; a parede interna (9) da base (1) conta ainda com um par de orifícios (13) associados e em posicionamento relativo com cada um dos suportes de montagem (10), ditos orifícios (13) servem para permitir a passagem, para fora da base (1), dos fios de conexão do transmissor (2) e do receptor (3).IMPROVEMENT INTRODUCED IN A SMOKE DETECTION DEVICE USED AS A COMPONENT OF FIRE SAFETY AND PREVENTION SYSTEMS, which comprises a base (1), an infrared light transmitter (2) configured as an LED, an infrared receiver (3) also configured as an LED, a light blocking disc (4), a tubular screen (5), and a cap (6); the base (1) has a contour wall (7) that acts as a means of delimiting the internal space (8), within which smoke detection will occur; the inner wall (9) of the base (1) incorporates two mounting brackets (10), one for receiving transmitter mounting (2) and one for receiving receiver mounting (3); the same inner wall (9) of the base (1) incorporates a pair of angular bulkheads (12) which act to precisely delimit the infrared transmission (2) and infrared reception ( 3) thus preventing improper perception of each other; the inner wall (9) of the base (1) also has a pair of associated holes (13) and in relative positioning with each of the mounting brackets (10), said holes (13) serve to allow outwards base (1), transmitter (2) and receiver (3)
