To stably confirm the presence/absence of abnormality between an emergency indicator lamp and a lighting device without lighting the emergency indicator lamp.SOLUTION: A line confirmation device 1 for emergency indicator lamp has a measurement state s1 where an alternating current for measurement is outputted to a line 4 between an emergency indicator lamp 2 and a lighting device 3, a disconnection state s2 of disconnection from the line 4, and a demagnetization state s3 where an alternating current for demagnetization for demagnetizing a transformer inside of the emergency indicator lamp 2 is outputted to the line 4. In the measurement state s1, abnormality of the circuit 4 is detected on the basis of the alternating current for measurement flowing to the line 4. When an alternating current for lighting is sensed in the line 4, the state is shifted to the disconnection state s2. When the alternating current for lighting is not sensed any more in the line 4, the state is shifted to the demagnetization state s3. After a predetermined time elapses in the demagnetization state s3, the state is shifted to the measurement state s1. The alternating current for measurement and the alternating current for demagnetization are set to voltage not to light the emergency indicator lamp 2.SELECTED DRAWING: Figure 2

    【課題】非常報知灯を点灯せずに、非常報知灯と点灯装置との間の回線の異常の有無を安定的に確認する。【解決手段】非常報知灯用回線確認装置1は、非常報知灯2と点灯装置3との間の回線4に測定用交流を出力する測定状態s1と、回線4から遮断された遮断状態s2と、回線4に非常報知灯2の内部のトランスを消磁するための消磁用交流を出力する消磁状態s3とを有する。測定状態s1において、回線4に流れる測定用交流に基づいて回線4の異常を検知する。回線4に点灯用交流を感知したとき、遮断状態s2に遷移する。回線4に点灯用交流を感知しなくなったとき、消磁状態s3に遷移する。消磁状態s3が所定時間経過したとき、測定状態s1に遷移する。測定用交流及び消磁用交流は、非常報知灯2を点灯しない電圧に設定される。【選択図】図2
