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

摘要

The internal resistance of a battery emergency moli gate of a danger alarm system with a charging circuit for these to monitor emergency accumulator, is provided between the emergency connection of the danger alarm system (1) and the accumulator (6) connected in a circuit, which periodically checks the internal resistance, and in the case of a value which lies outside a permissible range, an error signal is delivered to the danger signalling system. In terms of circuit engineering, this can be through a module (10) can be realized, the between the emergency connection (5a, 5b) of the danger alarm system and the storage battery terminals is inserted and periodically the internal resistance of the accumulator (6) measures.
