Abstract

Procedimiento para la evaluación de una tensión de línea constante que alimenta una línea de aviso con n avisadores (n >= 1) de una instalación de aviso de peligro en estado de reposo respecto de una resistencia inadmisiblemente elevada, con: limitación de una tensión en un extremo de la línea de aviso mediante un módulo terminal a un valor que es mayor que una tensión de trabajo mínima de un avisador; ajuste de una corriente de reposo de la línea de aviso mediante el módulo terminal a un valor que es mayor que la suma de corrientes de reposo de los n avisadores (n >= 1) y menor que una corriente de alarma de un avisador individual con su tensión de trabajo mínima; siendo realizados para la detección de una resistencia inadmisiblemente alta los pasos siguientes: medición de la corriente de reposo de la línea de aviso terminada mediante un módulo terminal, comparación de la corriente de reposo medida con un valor nominal y generación de un aviso de fallo al caer por debajo del valor nominal.Procedure for the evaluation of a constant line voltage that feeds a warning line with n warning devices (n> = 1) of a danger warning installation in rest state with respect to an inadmissibly high resistance, with: limitation of a voltage in one end of the warning line through a terminal module at a value that is greater than a minimum working voltage of a warning device; adjustment of a standby current of the warning line by means of the terminal module to a value that is greater than the sum of standby currents of the n warning devices (n> = 1) and less than an alarm current of an individual alarm with its minimum working tension; the following steps being carried out for the detection of an unacceptably high resistance: measurement of the quiescent current of the warning line terminated by a terminal module, comparison of the measured quiescent current with a nominal value and generation of a fault warning to the fall below the nominal value.
