For the past 6+ months I thought a flat nearby had a low battery smoke alarm, finally tracked it down to this device on a lamp post. It beeps really loudly every 30 seconds, 24/7.

  1. 30 seconds – it’s fine – if it starts beeping every 25 seconds – run

  2. Ffs. I think there is be near my house too. It’s insanely loud and I thought it’s someone’s car.

  3. Think it is something to do with busses? When a buss passes it updates its live location and updates all the expected times on bus stops. Why the beep? I don’t know.

  4. Impromptu Bleep Test generator. When you hear the bleep, run a short distance.
