て継電器２のｂ接点を開いておき同時に並列に入
つている継電器８のａ接点９も火災報知器の７接
点が動作して継電器８を動作しない限り開いてい
るので、５接点と９接点の並列回路により動作す
るランプ６は消灯しているが、単相低圧交流電源
１が何等かの原因で停電した際２の励磁が解かれ
て５接点が閉じ、ランプ６の回路が閉じてランプ
６が点灯する。又火災報知器が動作して接点７が
閉じ、継電器８が動作する。継電器８の３つのａ
接点９，１０，１１が閉じて直流電源回路−１が
閉じ、ランプ６が点灯すると同時に直流電源回路
−２の火災報知器警報ブザーも鳴り、継電器８は
自己保持されて、スイツチを開くまでランプ６は
点灯し、警報ブザー１３は鳴る。 Normally, the relay 2 is excited by the single-phase low-voltage AC power supply 1 to open the B contact of the relay 2, and at the same time, the A contact 9 of the relay 8 connected in parallel also activates the 7 contacts of the fire alarm, and the relay 8 is activated. Since it is open as long as it is not operating, the lamp 6, which is operated by a parallel circuit of 5 contacts and 9 contacts, is off, but when the single-phase low-voltage AC power supply 1 loses power for some reason, the excitation of 2 is released. Contact 5 closes, the circuit of lamp 6 closes, and lamp 6 lights up. Also, the fire alarm operates, contacts 7 close, and relay 8 operates. Three a's of relay 8
Contacts 9, 10, and 11 close, DC power supply circuit-1 closes, lamp 6 lights up, and at the same time the fire alarm alarm buzzer of DC power supply circuit-2 also sounds, relay 8 is self-held, and the lamp remains on until the switch is opened. 6 lights up and the alarm buzzer 13 sounds.
