Yes the fire alarm works.

Fire Alarm. Woke me up so I could deliriously try to turn the TV off to stop the awful sound even though it was not my tv. Search for pants in panic when I realized it was the fire alarm. Grab phone. grab keys. run out. Don't know what I'm doing. Scared to go down stairs. But finally saw other people and went. Saw neighbors all outside. all delierous. all awoken from sleep. all grumpy. all have doggies. Fire truck comes. Hot firemen. find out some idiot burnt toast. Thank you idiot on 3rd floor for testing out the fire alarms for us.
