Was designed an alarms central and access controller that has digital and analogical inputs for sensors and outputs for buzzer, telephonic dialing and electronic lock. The system is supervised by software that makes solicitations of information to the alarms central through the one computer's serial port (RS-232). The supervisory software was developed in platform LabVIEW with displays the received data on a graphical interface informing the sensors' current states distributed in the building and system events as alarns occurrences. This system also can be viewed through the Internet for people registered by the land security's system administrator / Este trabalho apresenta uma proposta de um sistema de seguran?a para automa??o predial, tendo como objetivo principal ? cria??o de um sistema que seja capaz de uma forma simples, monitorar as instala??es de um pr?dio a fim de atender as necessidades de prote??o patrimonial e pessoal, visando portabilidade, baixo custo e facilidade de uso. Foi projetada uma central de alarmes e controlador de acesso com entradas anal?gicas e digitais para sensores e sa?das para sirene, discadora telef?nica e fechadura eletr?nica. O sistema ? supervisionado por um software de monitoramento que f?z requisi??es de informa??es ? central de alarmes atrav?s da porta serial do computador (RS-232). O software supervis?rio foi desenvolvido na plataforma de desenvolvimento LabVIEW o qual disponibiliza os dados recebidos numa interface gr?fica informando os estados atuais dos sensores distribu?dos no interior do pr?dio e eventos do sistema como ocorr?ncias de alarmes. Este sistema tamb?m pode ser visualizado atrav?s da lnternet por pessoas cadastradas pelo administrador do sistema de seguran?a predial
