Gentex Hard-Wired Combination Smoke Alarm and Carbon Monoxide Detector

The Gentex GN503F operates by continuously monitoring the air in your environment. The device uses a photoelectric sensor to detect the presence of smoke, a common indicator of a fire. If smoke levels rise above a certain threshold, the alarm sounds, alerting inhabitants to the potential danger. Similarly, it also includes an electrochemical sensor to detect carbon monoxide, a deadly gas that is odorless, colorless, and tasteless. If the carbon monoxide level becomes hazardous, the unit will sound an alarm, providing a crucial warning of this invisible threat.

The Gentex GN503F is hard-wired, meaning it draws power from your building's electrical system. This ensures that the detector remains operational even in the event of power outages, thanks to its battery backup feature. The device also includes a Horn and Temporal 3 (T3) evacuation beeper for smoke detection and a Temporal 4 (T4) evacuation beeper for carbon monoxide detection, which are distinct, audible alerts that help you identify the type of threat detected.

One of the key features of the Gentex GN503F is its interconnected capability. This means that if one detector is in a series of alarms, all interconnected alarms will sound. This interconnection capability can be particularly useful in large homes or buildings where a problem in one area might not be immediately noticeable in another.

The Gentex GN503F also includes a quick-disconnect wiring harness that makes it easy to remove the alarm for cleaning or servicing. Additionally, the device comes with a push-button test feature that allows you to verify its operation easily. The alarm also includes a low or missing battery indicator, ensuring you're never caught off guard by a non-functioning detector.
