The Gentex GN-503F is a hard-wired, photoelectric smoke/carbon monoxide alarm designed to replace unreliable nuissance alarms.

This device is backed by a one year warranty, as well as a five year limited warranty on the carbon monoxide sensor. It features an 85dBA alarm horn at 10 feet, operates at 120 VAC, and has a 9V backup battery that provides power to the unit even after a power outage.
