I suspect it hovered until it ran out of batteries before landing on a man that was not too happy.http://blog.al.com/wire/2013/10/drone_falls_out_of_the_sky_in.html

We installed hard wired smoke detectors so that you don’t rely on tenants to replace batteries, fire extinguishers, CO2.

Some people go detector crazy which gives the tenants more batteries to take and during inspections all detectors most work so we keep it to the min.

I can see supplying batteries for smoke detectors.

Another city near me requires a permit for battery operated smoke detectors.

When I do the move in, tenants sign a condition statement that includes "smoke detector batteries were replaced on 9/1/12 and all smoke and carbon monoxide detectors were tested and found to be in working order".

You just need a battery for your calculator!

I'll go get new batteries for both.

They've been in the house for 11 months...batteries don't run down after 11 months...plus..they aren't that consiencious.
