SKU \u003cstrong\u003eKN-COP-DP-LS\u003c\/strong\u003e identifies this as the AC plug-in variant with digital display in the Nighthawk series — a product engineered for straightforward outlet installation combined with professional-grade monitoring capability. Powered directly from a standard 120V wall outlet, this alarm is always-on under normal power conditions, with the digital readout giving users and safety staff an at-a-glance view of CO levels without triggering a test alarm. For facilities managers, property managers, and safety coordinators who need reliable, branded CO protection with visual monitoring, the KN-COP-DP-LS delivers Nighthawk credibility in an easy plug-in form factor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel \/ SKU:\u003c\/strong\u003e KN-COP-DP-LS (Kidde Nighthawk AC plug-in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e AC plug-in (120V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e Digital CO ppm readout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Nighthawk — Kidde's field-proven CO alarm line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e UL 2034 listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Choose the Kidde KN-COP-DP-LS Nighthawk?\u003c\/h2\u003e\u003cp\u003eThe Nighthawk name has been synonymous with CO detection credibility for years. The KN-COP-DP-LS brings that reputation into a simple AC plug-in package that installs in seconds and provides continuous digital monitoring from the moment it's powered up. For safety buyers who want a trusted specification — one with a proven brand behind it and a clear digital readout that maintenance staff and building occupants can interpret without training — the KN-COP-DP-LS is a straightforward choice.\u003c\/p\u003e\u003cp\u003eThe AC plug-in form factor is ideal for locations where power is consistently available and where the convenience of outlet installation is preferred over hardwiring costs. Unlike battery-operated units that require ongoing battery replacement and monitoring, the KN-COP-DP-LS draws from a reliable AC supply, reducing maintenance overhead for property managers and building maintenance teams. The digital display means every site visit can include a quick visual CO check — replacing a reactive alarm-response model with a proactive monitoring approach.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAC plug-in power — continuous operation from standard 120V outlet\u003c\/li\u003e\n\u003cli\u003eNighthawk series — Kidde's established, field-proven CO detection line\u003c\/li\u003e\n\u003cli\u003eDigital display shows live CO concentration in parts per million\u003c\/li\u003e\n\u003cli\u003eElectrochemical CO sensor for stable, accurate detection over time\u003c\/li\u003e\n\u003cli\u003e85 dB audible alarm upon reaching CO alarm threshold\u003c\/li\u003e\n\u003cli\u003ePeak CO memory stores highest CO level recorded during an event\u003c\/li\u003e\n\u003cli\u003eEnd-of-life indicator alerts when sensor nears replacement interval\u003c\/li\u003e\n\u003cli\u003eTest\/reset button for routine monthly functional verification\u003c\/li\u003e\n\u003cli\u003eUL 2034 listed — meets most residential and light commercial CO code requirements\u003c\/li\u003e\n\u003cli\u003eOutlet plug-in installation — no tools, no electrician, no permits needed\u003c\/li\u003e\n\u003cli\u003eCompact Nighthawk housing — familiar form factor for users standardized on the brand\u003c\/li\u003e\n\u003cli\u003eNo battery replacement required under normal AC power conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReal-World Benefits\u003c\/h3\u003e\u003cp\u003eBuilding owners and property managers who specify the KN-COP-DP-LS benefit from Kidde's supply chain reliability and the brand recognition that Nighthawk carries among safety professionals. When a property is sold, inspected, or audited, having a recognized brand's UL 2034 listed CO alarm installed reads immediately as a professional safety specification — not an afterthought purchase from a discount store. The digital display reinforces that professionalism by demonstrating active monitoring rather than passive alarm presence.\u003c\/p\u003e\u003cp\u003eFacilities teams appreciate that AC-powered alarms eliminate the low-battery complaint cycle that plagues battery-only units. With the KN-COP-DP-LS, the alarm is always on, always monitoring, and always displaying CO data as long as the outlet has power. For routine safety inspection checklists, this simplifies the verification process: plug it in, confirm the display reads a value (zero or otherwise), and move on — no battery test required. The end-of-life indicator handles sensor replacement timing automatically, adding a further layer of maintenance simplicity.\u003c\/p\u003e\u003cp\u003eFor hospitality properties, senior living facilities, and educational settings where simple, reliable CO protection is needed across many rooms or units, the KN-COP-DP-LS's plug-in convenience makes large-scale deployment achievable without specialized labor. A property manager or maintenance tech can install a unit in every unit in a building in a single afternoon without electrical permits or contractor scheduling.\u003c\/p\u003e\u003ch3\u003eApplications \u0026amp; Ideal Use Cases\u003c\/h3\u003e\u003cp\u003eThe KN-COP-DP-LS excels in any setting with consistent AC power and a preference for outlet-based installation.

If protection during outages is a priority — particularly in locations where portable generators or alternate heating may be used during outages — the KN-COP-DP-B is the better choice. For locations with reliable power and a preference for simpler, lower-maintenance operation, the KN-COP-DP-LS is an excellent fit.\u003c\/p\u003e\u003ch3\u003eDoes the KN-COP-DP-LS work during a power outage?\u003c\/h3\u003e\u003cp\u003eNo. The KN-COP-DP-LS operates on AC power only and will not function during a power outage. If battery backup during outages is required, consider the KN-COP-DP-B or battery-operated models such as the KN-COPP-B-LP or KN-COPP-B-LPM. For locations where outage protection is essential, a backup battery model is recommended.\u003c\/p\u003e\u003ch3\u003eHow do I read the digital display?\u003c\/h3\u003e\u003cp\u003eThe digital display shows the current ambient CO concentration in parts per million (ppm). A reading of 0–9 ppm represents normal background conditions. The display also shows L (low) or numerical readings during alarm events, and provides status indicators for end-of-life and other conditions. During alarm conditions, follow established emergency procedures regardless of the displayed ppm value.\u003c\/p\u003e\u003ch3\u003eHow often should I test the KN-COP-DP-LS?\u003c\/h3\u003e\u003cp\u003eKidde recommends testing CO alarms at least once per month using the test\/reset button. This verifies that the alarm circuitry and audible alarm are functional. Monthly testing also confirms the digital display is operating and the unit remains properly plugged in and powered.\u003c\/p\u003e\u003ch3\u003eIs the Nighthawk series being discontinued?\u003c\/h3\u003e\u003cp\u003eKidde continues to support the Nighthawk series for existing installations and ongoing sales.
