My dream talk recorder app picked up my smoke alarm which went off for some unknown reason at 4 am. There was no emergency but thought someone might want to use the sound.
Three regular beeps of a smoke alarm, followed by one final slowly dying beep. Warning, this is super loud and ear-piercing compared to other sounds, turn your volume waaay down before testing out this sound.
Smoke detector test noise, recorded roughly 20cm from mic without room reflections. Fundamental frequency: ca. 3373 hzovertones: ca. 6743 hz; 10111 hz, 13482 hz.

I recorded a beep that is coming from outside my flat, don't know what it is, perhaps a smoke alarm or a light sensor is in distress. Applied some noise reduction and effects to produce this sound.
