The Kidde 0919-9999 Battery-Operated Wireless Smoke Alarm allows for the easy installation of an interconnected smoke alarm system without the high cost and hassle of rewiring your home. The alarms are wirelessly linked so that when one alarm is triggered, all alarms will sound. This alarm can also be placed in a detached workshop or shed and linked into the home’s interconnected system. Experts recommend interconnected alarms, because when one sounds, they all sound, 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. Newer homes are required by code to have interconnected alarms. Wireless technology now enables any home to have an interconnected system. This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home. Choose the Right Wireless Alarms for Your Home Kidde offers two wireless product options: a Battery Powered Smoke Alarm, and an AC Powered Smoke Alarm. These products enable you to customize your system based on your specific needs. Read below to see which Kidde wireless smoke alarms are best for your home. Why Wireless?

Getting Started with Wireless Interconnect in Three Easy Steps Step 1 – Determine the type of smoke alarms currently installed in your house. 1. Battery Powered No wires; runs only on batteries. Most older homes have battery-powered smoke alarms. These alarms have no protruding wires and are battery powered. 2. Hardwired Runs on your home’s electricity and may have battery backup. Only one alarm sounds when test button is pressed. If your home was built in the last 20 years, you probably have hardwired smoke alarms. If only the alarm that you test sounds, then you do not have an interconnected system. 3. Interconnected Runs on your home’s electricity and may have battery backup. All alarms sound when one test button is pressed. Homes built in the last 15 years may have an interconnected smoke alarm system. If all alarms sound when you test, you have an interconnected system. Step 2 – Decide how many alarms you need in your home. The NFPA recommends at least one smoke alarm on every level of the home and in every sleeping area. Step 3 – Based on your home’s current alarm set-up, decide which Kidde Wireless alarms to purchase. 1. If your home has only battery powered alarms: Purchase enough Kidde Wireless Battery Powered Smoke Alarms (0919-9999) to replace all of your current smoke alarms. You will also have the ability to add Kidde Wireless Battery Powered Alarms in additional rooms for expanded coverage. 2. If your home has only hardwired smoke alarms: Purchase enough Kidde Wireless AC Powered Smoke Alarms (1279-9999) to replace all of your current smoke alarms. You will also have the ability to add Kidde Wireless Battery Powered Alarms in additional rooms for expanded coverage. 3. If your home has interconnected smoke alarms: Purchase one Kidde Wireless AC Powered Smoke Alarms to replace one current smoke alarm. Kidde Wireless Battery Powered Alarms can then be installed in additional rooms. Interconnectable for Improved Safety Fire and consumer experts recommend interconnected alarms for added protection. According to the National Fire Protection Association (NFPA), most Americans feel they are more at risk of being a victim of a tornado than of a house fire. Actually the opposite is true. Fires are more common than any other disaster that strikes a family at home, and can become deadly in minutes. You have on average less than three minutes from the time you hear a smoke alarm to escape a fire. The sooner you hear an alarm, the sooner you can get out safely. Smoke alarms that link together so that when one goes off, they all go off, are called interconnected alarms. These alarms provide more warnings in more places, giving your family more time to escape a house fire. Houses built after 1993 are required by building codes to have interconnected alarms that are wired into their electrical system. Trademarked Hush Feature for Convenience By pressing the Hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners. This alarm’s Smart Hush feature has the capability of temporarily desensitizing the alarm circuit for up to 8 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. The red LED will illuminate for 1.5 seconds every 8 seconds while in hush. This indicates that the alarm is in a temporarily desensitized condition. The smoke alarm will automatically reset after approximately 8 minutes and sound the alarm if particles of combustion are still present. Smart Hush can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Hush button on the alarm will end the hush period. 3-AA Batteries, Indicator LED, and Test Feature Because a smoke alarm only helps protect you if it’s working, this unit features a red LED that flashes every 10 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn. The alarm’s 3-AA batteries provide continuous protection against smoke and fire hazards, even during power outages. The unit offers a low battery warning that issues a brief chirp every 30 to 40 seconds for at least seven days before losing power, letting you know that it’s time to change the battery. This alarm is UL listed, so you can be confident of its quality, and it is backed by a 10-year limited warranty that lasts the life of the alarm.

Protect your family from the dangers of carbon monoxide (CO), methane, and propane exposure with the Kidde KN-COEG-3 Nighthawk Plug-In Carbon Monoxide and Explosive Gas Alarm. The Nighthawk is an easy-to-install unit that provides reliable protection against the dangers of CO and explosive gas. The digital display shows if gas is present indicates CO levels in parts per million, allowing you to see if, how, and when levels change.

Advanced Technology in an Easy-to-Install, Plug-In Design
Designed for home use, the Kidde KN-COEG-3 Nighthawk is a UL-listed, A/C-powered, plug-in alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO, methane, and propane exposure. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring–even during power outages.

The Dangers of Carbon Monoxide, Methane, and Propane Exposure
The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it’s odorless, tasteless, and invisible. Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed.

Likewise, methane and propane gases are commonly used in homes for cooking, heating, and water heating. Although it happens rarely, gas leaks can sometimes occur inside the home, increasing the risk of fire or explosion.

Audible Alarm Pattern Alerts you to Elevated CO and Gas Levels
When placed on every level of your home, alarms like the KN-COEG-3 Nighthawk can help protect everyone in the house by giving you an unmistakable signal when gas levels have reached an unhealthy point. If unhealthy levels of CO are detected, the alarm will emit four quick audible beeps every five seconds until either levels decrease or the reset button is pressed. If methane gas or propane gas is detected, the alarm will emit beeps every other second with “GAS” shown in the display.

Easy-to-Read Digital Display Shows CO Levels
The KN-COEG-3 Nighthawk is preferred among traditional CO and explosive gas alarms because of its digital display. This display clearly shows levels of CO that the unit has detected and stored– from 30 to 999 ppm–and it updates every 15 seconds to indicate any abrupt changes or alarming trends. The display also shows the peak CO level recorded by the alarm since it was last reset or unplugged. The continuous display also shows if gas is present.

LED Shows Sensor Status
With the KN-COEG-3 Nighthawk, you never have to wonder if the sensor is functioning properly. A blinking dot in the lower right-hand corner of the display denotes normal operation, so you can trust that it’s working. In addition, you can test alarm function by pressing the test/reset button at any time to verify that the horn and electric circuitry are operating properly.

Convenient Mounting Options
The KN-COEG-3 Nighthawk has a low-profile design that makes it suitable for any room in your home. The detector can be plugged into any standard A/C outlet; it’s plug can be snapped into the back of the unit and can be rotated so the alarm remains vertical, independent of whether the electrical socket is mounted vertically or horizontally. In addition, the alarm comes with a 6-foot extension cord, so the unit can be plugged into the wall outlet and then placed on a table or shelf. For the most thorough protection, place an alarm on every level of your home.

The UL-listed Kidde KN-COEG-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

From the Manufacturer

In the event of a fire every second counts. If a fire were to begin in your basement and the alarm there sounded, you may not hear it right away if you’re sound asleep two floors up. With traditional battery-operated alarms, you lose valuable time waiting for the smoke to rise to another alarm, on another level, before the alarm on your floor sounds. But with First Alert ONELINK alarms, if one detects danger, they all sound. This can alert you sooner, and it increases your chances of getting out safely. Until now, alarms that could signal each other were only available in homes with hardwired alarms requiring installation from an electrician. But First Alert ONELINK alarms communicate without wires. ONE Link-with Voice Location Smoke alarm is programmable with up to 11 locations in your home – when alarm sounds it will tell you the location of the smoke. The wireless feature allows multiple alarms to talk to each other – when one alarm sounds, they all sound. The wireless network operates on 914 MHZ 3 channels and will not interfere with other electronics. The ONELINK smoke alarms uses photoelectric sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. A low battery signal alerts you to replace the battery. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit’s functionality. The AA batteries are easy to install in the convenient pullout battery drawer. Two AA batteries included.

This easy-to-install First Alert Z-Wave ZCOMBO-G Smoke and Carbon Monoxide Alarm is designed for compatibility with certified First Alert enabled Z-Wave Devices.
