3-Pack Battery-Powered Smoke and Carbon Monoxide Detectors with Digital Display and Dual Alarm Sensors, Easy Installation, Black

Product Description: Enhancing Security with Smoke and Carbon Monoxide Detector

The JNHCD brand smoke alarm sensor utilizes a photoelectric smoke alarm sensor, also known as an optical maze, which is a technologically advanced, stable, and reliable sensor. For carbon monoxide detection, the JNHCD employs an electrochemical sensor, recognized as the most accurate CO sensor available. Electrochemical technology, used in this sensor, offers high accuracy, low power consumption, and extended lifespan compared to other common techniques. When the JNHCD sensor detects high CO levels, it triggers a loud 85-decibel alarm, providing ample time for ventilation or evacuation.

This battery-operated dual CO smoke alarm can be easily installed within minutes without the need for an electrician. It operates on 3*1.5v AA batteries and includes a chirp and indicator light to signal when battery replacement is necessary. Suitable for various locations where people spend extended periods, such as living rooms, bedrooms, hallways, basements, and cars, this alarm system is simple to install in any area of the home.

To install, twist the alarm body counterclockwise to detach it from the bracket. Position the bracket as per the recommended locations, mark the installation holes with a pencil, drill the holes using a 3/16 inch (5mm) drill bit, insert the plastic grommets with a hammer, secure the bracket to the ceiling with screws, and finally, attach the alarm to the bracket by twisting it clockwise until fully secured.

For optimal safety, install the alarm in living rooms, ceilings, cars, or other areas where people spend significant time. Ideal locations include bedrooms, hallways, basements, cars, or living rooms.

Sound and light alarms from the smoke and carbon monoxide detectors ensure you stay informed of any potential danger, keeping you and your family safe. Common sources of CO in homes include fuel-burning appliances like clothes dryers, water heaters, furnaces, fireplaces, gas stoves, and more.

Featuring an information LCD display with switch buttons, this detector shows gas concentration levels, allowing continuous monitoring of CO and smoke levels. The loud 85-decibel siren alerts occupants when gas levels exceed safety thresholds, with a single button for silencing alarms and testing device functionality.

In summary, the Smoke and Carbon Monoxide Detector offers top-notch security by emitting a loud 85 dB alarm upon detecting smoke or CO buildup, equipped with an accurate electrochemical sensor and infrared photoelectric sensor to minimize false alarms. Providing round-the-clock protection, this battery-powered unit can be swiftly installed without professional assistance, backed by a 5-year manufacturer's warranty.
