French Phrase
J'ai activé l'alarme ?
Meaning
Literally, “Did I turn on the alarm?” The speaker is checking whether they have already set the alarm, often after hearing a sound or when leaving a room.
When to use
Use this sentence when you are unsure if you have already activated a security or fire alarm, a home alarm system, or even a phone alarm. It works in both formal and informal contexts, but the rising tone makes it sound conversational.

Cultural Tip
In French, both 'activer' and 'mettre en marche' are common for alarms, but 'activer' sounds a bit more technical (e.g., security systems). When speaking to older generations, you might hear 'mettre l'alarme' more often. Also, French speakers often add a confirming tag like 'non ?' at the end of statements to turn them into a question.
