感知器。(1) The signal processing circuit is driven by a non-self-holding switching circuit that responds to the smoke output signal of the signal processing circuit that detects smoke, and is driven by a constant voltage circuit that steps down the voltage of the smoke detection line from the warning special voltage to the alarm voltage. A smoke detector that supplies and maintains a voltage capable of detecting smoke, and automatically recovers when it is below the smoke detection level.
圧を互いに異ならしめてなる実用新案登録請求の範囲第
１項記載の煙感知器。(2) The smoke detector according to claim 1, wherein a plurality of smoke detectors connected to the same line have different alarm voltages.
