Part Five – Technical Information

How the Unit Determines When to Alarm

Your Nighthawk CO alarm uses advanced technology to monitor the environment in your home and warn you of unacceptable levels of carbon monoxide. An internal microcomputer works together with the carbon monoxide sensor inside the CO alarm to determine the levels of carbon monoxide in the air and to calculate the rate that CO would be absorbed into the human body.

The microcomputer is calibrated to trigger the unit’s alarm before most people would experience any symptoms of carbon monoxide poisoning. Because carbon monoxide is a cumulative poison, long- term exposures to low levels can cause symptoms, as well as short- term exposures to high levels. Your Nighthawk CO alarm has a time weighted alarm, so the higher the level of carbon monoxide pre- sent, the sooner the alarm will be triggered.

This Nighthawk CO alarm meets the alarm response time requirements of UL Standard 2034 which are as follows:

At 70 ppm, the unit must alarm within 60-240 minutes. At 150 ppm, the unit must alarm within 10-50 minutes. At 400 ppm, the unit must alarm within 4-15 minutes.

WARNING: This device may not alarm at low carbon monoxide levels (see chart above for alarm points). This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical problems may consider using warning devices which pro- vide audible and visual signals for carbon monoxide concentrations under 30 ppm.

Accuracy of the Digital Display

Each Nighthawk CO Alarm is calibrated at a CO concentration of 150 ppm (+/- 25 ppm) in air, at 80˚ F (+/- 10˚ F) and 40% (+/- 3%) relative humidity. Depending on the ambient condition (temperature, humidity) and the condition of the sensor, the alarm readings may vary.

The digital reading tolerances are:

Ambient: 80˚ F (+/- 10˚ F), atmospheric pressure +/- 10%, 40% +/- 3% relative humidity.

Nighthawk KN-COP-HW, KN-COP-C, KN-COP-DP warranty Part Five Technical Information

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.
