Question About Nighthawk Carbon Monoxide Alarm 900-0014-01
intermittent audible alarm every 25 seconds...

I lost the manual, but on the back of the unit, it says that intermittent audible alarms every 25 seconds is a unit error. It seems to have stopped, there is no battery backup inside the unit. What is the type of unit error?
