I may have overdone it on the translation, but here is everything explained:
TRANSLATION:
Original:
昭和９年９月
神奈川電氣株式會社
第1778號

English Translation:
September 1934
Kanagawa Electrical Co., Ltd.
Issue No. 1778

Literal translation:
9th month of the 9th year of the reign of Shouwa
Kanagawa Electrical Stock Company
The 1778 Issue

BREAK DOWN:

Japanese: 昭和９年９月
Romaji: Shouwa kyunen kugatsu
English: Shouwa 9th Year 9th Month (September) {By the regular calendar that's September 1934}

Japanese: 神奈川電氣株式會社
Romaji: Kanagawa Denki Kabushikigaisha
English: Kanagawa Electrical Co., Ltd.

Japanese: 第1778號
Romaji: Dai ichi nana nana hachi gou
English: Issue No. 1778

NOTES:
- 'Shouwa' denotes the era of Emperor Shouwa, Hirohito. It says the '9th Year', Hirohito reigned from 1926, meaning the 9th year of his reign was 1934.
- 電氣 meaning 'electricity' is written simplified as 電気 today, 會社 meaning 'company' is written as 会社 today, and 號 meaning 'issue' is written as 号 today. These old forms of kanji stopped being used in 1949 after the Japanese language reform of that year - my friend who also speaks Taiwanese helped me to figure out what these kanji were as Taiwan still uses the traditional Chinese kanji. Most Japanese don't write these old kanji anymore.
- 第 translates as 'the' and only comes before a number, to say 'this object is the (number) of this type'
- 株式會社 literally translates to 'Stock company', but in English it's the same as 'Company Limited'.

So, what is written isn't extremely interesting, but I hope this was interesting for you to read and learn more!

The ID tag on the air raid siren says it was made in September 1934, serial number 1778. And my pre-WWII kanji understanding may be a bit off, but it looks like it was made by Kanagawa Electric Company.

1 life = 1 poor air raid siren saved from abusive owners

Don’t destroy the World War Two airhorn, my great grandpa fought in World War Two, he made it back home but many did not. Those horns were used to warn people. Many people died and those horns were the last thing they heard. Keep the horn safe or donate it to a museum. Thank you 🙂

[kickedgaming]

Goodness, these neighbors must think an actual air raid is going on...
