私はあなたの煙探知器をテストするためにここにいます

Hello sir, I've come to check the fire alarms in the area.

I thought I'd check your flat. Is that ok? I just need to do a quick test of the fire alarms.

God, safety is paramount. Smoke is a killer.

I need to make sure you are ok. You've just got one up here. Do you mind if I just reach up and get it for you?

My back, that is what some serious size.
