quadrant 6

ok, so....when i arrived at work the fire/security alarm by the front door was beeping loudly....and though we have the key to disarm it we called the fire department to come on over and heck out the building just in case. It seems the alarm is tied to neither the police or fire departments, nor the upstairs in our building for that matter.....and the conundrum alarm kept going off....and we stopped calling the fire department....when we figured out that the message that was blinking was not quadrant 6 but trouble b...as in battery...it was nothing more than the battery in a smoke alarm that has started the whole thing chirping......omg.....i live and learn.....
