1. Siri notifies me on my decides if a smoke alarm goes off. Thanks, Siri. 2. I can hear the smoke alarm throughout the house. Great. 3. Smoke alarms sounding is an excellent way to wake up the cat. 4. The cat evacuates the house efficiently when the smoke sounds. Also great. <more>

5. Drawing the curtains at night is an excellent idea in case I stand stark naked in the living room staring at the smoke alarm with all the light on early in the morning, startling the neighbours and passengers in passing buses. I still don’t know what set off the smoke alarm.
