Gentex GN-503F Combination Photoelectric Smoke & Carbon Monoxide Alarm
Also known as: GN503F, GN-GN503F
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.
With Dual Link tones, a self test push button, a low-battery indicator, and a 5 year service life, the Gentex GN-503F is a beacon of high-performance smoke and carbon monoxide detection. It comes with a fast disconnect wiring harness, a non-latching alarm, and is able to connect to 12 other Gentex combination smoke and carbon monoxide alarms.
