First Alert's series of Wireless Battery Operated Smoke Alarms effectively eliminates the need for a wired connection and operates entirely on batteries. The latest advancement in a series celebrated for its intuitive use of technology, the First Alert Wireless Interconnect collection offers an abundance of options when it comes to creating the ideal safety network. Wireless inter-connectivity allows you to connect up to 16 alarms within your home! Should one First Alert Wireless Interconnect alarm sound off, the remainder of your Wireless Interconnect alarms will also trigger simultaneously and alert you and your home to any potential dangers. The communication distance (range) between any two First Alert Wireless Interconnect Alarms is typically 50 ft. (15 meters) inside of a home. Some features of a home, such as the number of floors, number/size of rooms, furniture and types of building materials used may reduce the range of wireless interconnect alarms. This feature allows for the maximum in whole home protection.
The realization of Photoelectric Smoke Sensing Technology will effectively reduce the number of nuisance alarms triggered by cooking smoke and shower steam. This alarm comes equipped with a Mute Button that serves the dual purpose of quickly silencing your alarm as well as testing its function. First Alert Wireless Interconnect Battery Operated Smoke Alarms also come equipped with an EZ access battery door that removes the hassle and burden of collecting your alarm from the ceiling and replacing its batteries. The combination of an optional theft-prevention lock and an increased emphasis on the unit's 85db sound output establishes peace of mind, while the inclusion of an anti-theft prevention lock all but guarantees the safest of experiences. This alarm comes with a 10-year limited warranty and meets UL217 Standards.

Actual battery service life depends on the particular design of your smoke or carbon monoxide alarm and the environment in which it is installed. All kinds of alarm batteries specified in the user's manual are acceptable replacement batteries. Regardless of the manufacturer's suggested battery life, you MUST replace the batteries immediately once the unit starts "chirping" (the "low battery warning"). It is recommended that you change the batteries in your alarms when you change your clocks for daylight saving time. Also consider replacing your current alarms with 10-Year Life Alarms that never require a costly battery replacement for the ten year life of the alarm. This 10-Year series is available in smoke, carbon monoxide and combination alarms.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
Smoke alarms have a limited life. Although each smoke alarm and all of its parts have passed many stringent tests and are designed to be as reliable as possible, any of these parts could fail over time. Therefore, you must test the devices weekly. The unit should be replaced immediately if it is not operating properly. The performance of smoke alarms older than 10 years is simply not reliable. To ensure your family's safety, all carbon monoxide and smoke/CO combination alarms need to be replaced every 5-7 years. All smoke alarms need to be replaced every 10 years.
If it's time to replace your alarms, consider the NEW 10-Year Life series and never have to worry about a battery replacement for the life of the alarm.10-Year alarms are available in smoke, carbon monoxide and combination alarms.

We've been installing these in houses we rent, and this past December one of our tenants awoke in the middle of the night to these smoke alarms all going off at once. Long story short, our tenant made it out of the house in time. These worked as described when it mattered.

All Alarms are linked!
Just installed 6 of the First Alert Wireless Interconnect Smoke Alarms. Tested them and they work great. When one alarm is triggered, they all start sounding.
