Ante la presencia de humo genera una alarma audible local autorrestablecible que no se transmite al panel ni activa el relevador; solo el sensor t\u00e9rmico puede iniciar una alarma en el panel y cambiar el estado del relevador Forma C. Est\u00e1 dise\u00f1ado para sistemas convencionales de 4 hilos (tetrafilar) y se instala sobre una base de montaje de inserci\u00f3n r\u00e1pida incluida. Se utiliza en ambientes donde se busca una alerta local temprana por humo sin generar una alarma general innecesaria en el panel.<\/p>\n<h3 style=\"color: inherit;0.3);padding-bottom: 8px;margin-top: 24px\">Caracter\u00edsticas principales<\/h3>\n<ul style=\"padding-left: 20px;margin-bottom: 24px\">\n<li>Sensor fotoel\u00e9ctrico de humo aislado del sensor t\u00e9rmico fijo a 57.2\u00b0C<\/li>\n<li>El sensor de humo genera alarma audible local autorrestablecible que no activa el panel ni el relevador<\/li>\n<li>Solo el sensor t\u00e9rmico inicia la alarma en el panel y cambia el estado del relevador<\/li>\n<li>Relevador Forma C de 2 A a 30 Vca\/Vcd<\/li>\n<li>Algoritmos de autocompensaci\u00f3n de sensibilidad por ensuciamiento y rechazo de EMI\/RFI<\/li>\n<li>Base de montaje incluida con sistema de inserci\u00f3n r\u00e1pida Stop-Drop &#8216;N Lock<\/li>\n<li>Cableado tetrafilar (4 hilos); corriente de alarma de 50 mA<\/li>\n<\/ul>\n<h3 style=\"color: inherit;0.3);padding-bottom: 8px;margin-top: 24px\">Especificaciones t\u00e9cnicas<\/h3>\n<div style=\"display: flex;flex-wrap: wrap;gap: 12px\">\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">VOLTAJE<\/strong><span>12\/24 Vcc&amp;comma; tetrafilar 10-35 V<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">CORRIENTE EN ALARMA<\/strong><span>50 mA<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">RELEVADOR<\/strong><span>Forma C&amp;comma; 2 A a 30 Vca\/Vcd<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">ALARMA AUDIBLE (HUMO)<\/strong><span>85 dB&amp;comma; autorrestablecible<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">SENSOR T\u00c9RMICO<\/strong><span>Fijo a 57.2\u00b0C (135\u00b0F)&amp;comma; aislado del sensor de humo<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">SENSIBILIDAD<\/strong><span>2.5%\/pie&amp;comma; nominal<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">DIMENSIONES<\/strong><span>134 mm de di\u00e1metro x 51 mm de altura<\/span><\/div>\n<div style=\"flex: 1 1 200px;0.3);border-radius: 6px;padding: 12px;background-color: transparent\"><strong style=\"display: block;font-size: 12px;text-transform: uppercase;color: inherit;opacity: 0.8;margin-bottom: 4px\">CERTIFICACIONES<\/strong><span>UL&amp;comma; FM&amp;comma; CSFM&amp;comma; MEA<\/span><\/div>\n<\/p><\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Marca <b>SYSTEM SENSOR<\/b> \u00b7 Modelo <b>4WITAR-B<\/b><\/p>\n<p>Producto original con garant\u00eda de f\u00e1brica.
