Part Three – What You Should Know Before the Alarms Sounds

Learn the difference between dangerous levels, high levels, mid levels and low levels:

Dangerous levels, when someone is experiencing symptoms of CO poisoning and CO readings are generally above 100 ppm. Anytime someone is experiencing the symptoms of carbon monoxide poisoning this should be treated as an EMERGENCY. Follow the instruc- tions on page 4-2.

High levels, generally above 100 ppm, with no one experiencing symptoms. This should be treated as an URGENT situation. Follow the instructions on page 4-2.

Mid levels, generally between 50 ppm to 100 ppm. This should be cause for CONCERN and should not be ignored or dismissed. Follow the instructions on page 4-2.

Low levels, generally below 50 ppm. This indicates a need to watch the situation closely to see if it resolves itself or worsens. Follow the instructions on page 4-3.

Determine if anyone in the household is at high risk for CO poisoning:

Many cases of reported carbon monoxide poisoning indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance.

You should take extra precautions to protect high risk persons from CO exposure because they may experience ill effects from carbon monox- ide at levels that would not ordinarily affect a healthy adult. Are there any infants or small children in the home? Be sure to check them for signs of possible CO poisoning because they might have trouble explaining their symptoms. Infants and children are more susceptible to CO poisoning than a healthy adult.

Pregnant women should be aware that their unborn fetus could be harmed by exposure to carbon monoxide, even when the mother suffers no ill effect herself. Any pregnant woman who suspects she may have been exposed to carbon monoxide should immediately contact her physician.

Is there anyone in the household who is elderly, or who has anemia, heart disease or respiratory problems, emphysema or chronic bronchitis? These individuals are at higher risk for CO poisoning and for health problems from exposure to low levels of carbon monoxide.

Part Three – What You Should Know Before the Alarms Sounds

If anyone in the household is at high risk for CO poisoning, we urge you to take extra precaution to prevent possible poisoning. If the unit alarms or if CO readings are shown on the digital display, remove the at-risk person from the premises, if possible. Ventilate the area. The high-risk person(s) should not re-enter the residence until the source of the CO problem has been identified and corrected.

KN-COP-HW, KN-COP-DP, KN-COP-C specifications

The Nighthawk KN-COP series, which includes the KN-COP-HW, KN-COP-DP, and KN-COP-C models, represents a significant advancement in the realm of smoke and carbon monoxide detection technology. Designed with user safety and convenience in mind, these models integrate innovative features to ensure reliable performance in residential and commercial spaces.

One of the standout characteristics of the KN-COP series is their dual-sensor technology. This feature enhances detection capabilities by incorporating both photoelectric and ionization sensors. The photoelectric sensor is particularly effective in detecting smoldering fires, while the ionization sensor quickly identifies flaming fires. This combination allows the devices to respond accurately to a variety of fire scenarios, thereby increasing overall safety.

The KN-COP-HW model also boasts a sleek, modern design that fits seamlessly into any decor while being functional. It features a voice alarm system that clearly announces the type of danger detected, whether it's smoke or carbon monoxide, ensuring that users can react appropriately without confusion. Additionally, an LCD display provides real-time updates about CO levels, temperature, and battery status.

Another notable feature across the KN-COP lineup is the ease of installation and maintenance. Each unit is equipped with a battery backup, ensuring continuous operation even during power outages. The user-friendly design includes a simple test/silence button, making periodic checks and silencing false alarms hassle-free.

The KN-COP-DP variant elevates safety with advanced connectivity options. This model can be interconnected wirelessly with other Nighthawk units, allowing for synchronized alerts throughout larger spaces. This interconnected network provides comprehensive coverage, ensuring that everyone within the building is alerted in case of a potential emergency.

For users looking for a compact solution, the KN-COP-C model is engineered for optimal performance within smaller spaces. It retains the essential features of its counterparts but in a form factor that is easier to integrate into compact living environments.

Overall, the Nighthawk KN-COP series exemplifies a commitment to quality, safety, and innovative technology. Whether it's the homeowner seeking peace of mind or a business aiming to protect its assets, these detectors serve as a formidable first line of defense against the dual threats of smoke and carbon monoxide, ensuring that safety always comes first.
