Powered by a 120V wired source with a 10-year sealed lithium battery backup, it guarantees uninterrupted protection. Its wireless interconnect feature links up to 24 devices, ensuring whole-home alerts with clear 85-decibel voice warnings. Ambient light sensing prevents false nighttime chirps, while LED indicators provide real-time status updates. UL certified with a decade-long limited warranty, this alarm is engineered for reliable, smart home safety. ## Description The Kidde Wireless Hardwired Smoke Detector, 10-Year Battery Backup, Voice Alerts, Photoelectric Sensor Wire-Free Interconnect Combination Alarm, model p4010ACSCO-W, is a wireless smoke detector that uses photoelectric sensor technology to detect visible fire particles (associated with smoldering fires) & an electrochemical sensor to detect CO gas. When smoke or fire is detected, an 85-decibel alarm will sound, the ring on the detector will turn red, & a voice alert will announce, "Fire! Fire!". The Kidde Wireless Smoke Alarm enables the extension of coverage & protection without any need for additional wiring. When one alarm sounds, they all do, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the fire starts. The Kidde Wireless Smoke Detector is powered by a 120V wired power source with a 10-year lithium battery backup, which eliminates the need for battery replacements & provides coverage during a power failure. When the smoke alarm is at the end of its life span, the detector will announce, "Replace Alarm!" A test-hush button allows you to test the battery operations as well as silence nuisance alarms that may occur from cooking or shower steam. The Kidde Smoke Detector will chirp when it's time to replace the battery, however, an Ambient Light Sensing feature helps to prevent the alarm from chirping in dark conditions. The Kidde smoke detector can be used as a single unit or interconnected with up to 24 Kidde devices (18 of which can be initiated) in a multiple-station arrangement, not exceeding the NFPA (National Fire Protection Association) limit of 18 initiating devices (smoke, heat, CO). It is possible to interconnect 6 strobe lights and or relay modules. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Certified with a 10-year limited manufacturer's warranty. ## Features - Photoelectric sensor technology senses visible fire particles, associated with smoldering fires, while an electrochemical sensor senses carbon monoxide - Smoke alarm operates on a 120V wired power source with a 10-year sealed lithium battery backup - Voice Alarm & an 85-decibel alarm announces a hazard when detected: “Fire!” = smoke or fire, "Warning! Carbon Monoxide!", or "Replace Alarm" when the alarm has reached its end-of-life span - Enables extension of coverage & protection without any need for additional wiring - Ambient Light Sensing feature establishes a day/night cycle and prevents late-night battery chirps in dark conditions - LED warning light indicators alert you to various statuses: a green light indicates the unit is in proper working operation, an amber light indicates an operating error, and a red light indicate smoke or fire - Interconnection capability: allows you to connect up to 24 Kidde smoke, heat, or CO alarms, with the possibly it interconnect 6 strobe lights or relay modules - UL listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim).

WIth the P4010 wireless alarms, that originating alarm setting off all of the others will have a green light flashing every second while all of the alarms are going off. This will be the alarm you will want to HUSH. This is done intentionally so that you will examine the area where the alarm is before you hush the alarm and the system. These alarms also have a locate feature on them. From the owner's manual: In an interconnected system (all units will be alarming together), a unit that detects smoke or CO and initiates an alarm is called the “initiating alarm unit.” Initiating alarm units will be flashing the Green LED every second during alarm. Depending on unit locations, and the location of the source of smoke or CO, it is possible to have more than one initiating unit. If you suspect a nuisance alarm situation, you can use this feature to help you locate the initiating alarm unit(s) in a wireless alarm interconnect system. Push the button on any non-initiating wireless unit, and ALL wireless units EXCEPT the initiating alarm unit(s) will silence for two minutes. You can use the LOCATE feature repeatedly until you find the initiating alarm unit(s), or the air has been cleared of the condition causing the alarm. **Q: Can it run with out being hardwired in** A: Hello. This alarm has to be hardwired in and the battery is only a backup battery. It will definitely last more than a week but will not last the whole ten years on battery alone. Probably somewhere around weeks to months, possibly years. If you want an alarm without being hardwired, you will want the P4010DCSCO-W. https://www.kidde.com/home-safety/en/us/products/fire-safety/combination-smoke-co-alarms/p4010dcsco-w/ **Q: Does this connect with p4010dcsco** A: Yes **Q: Scared of installing one of these. Any info about date of manu., etc, on bad units? The one I havw says "RevA"** A: Mine lasted 5 months and then started having false alarms at all hours of the day or night. 3 days later another unit started doing the same thing.
