Method and circuit for monitoring a emergency accumulator moli gate of a danger alarm system

摘要

A method for operating a danger alarm system (gma) with a emergency accumulator (6) which adjoins a emergency connection (5a, 5b) of the danger signalling system (gma) is connected, and a controlled charging circuit (5), wherein the danger signalling system (gma) comprises the following operating states:Loading of this emergency accumulator moli gate (6),periodic monitoring of the voltage of the battery emergency moli gate (6) by means of voltage measurement and comparison with a setpoint value,the danger alarm system (gma) generates an error message, if the measured voltage falls below the predetermined value,the method comprising:Grinding of a circuit (10) between the emergency connection (5a, 5b) and the emergency accumulator (6), the the internal resistance (r_i) of the battery emergency moli gate (6) periodically checks and in the case of a value which lies outside a permissible range, an error signal in the form of a. Voltage at the emergency connection (5a, 5b) is generated, which is smaller than the reference value of the voltage of the battery emergency moli gate (6) is.
