First Alert Combination Smoke and Carbon Monoxide Alarms work exceptionally well in detecting smoldering fires. Leaps in ingenuity and technology have allowed this alarm to successfully decipher between nonhazardous and potentially life threatening smoke patterns. 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.
Combination Smoke and Carbon Monoxide Alarms utilize an Electrochemical Sensor that allows for optimal efficiency in detecting carbon monoxide. This alarm also comes 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 End of Life Timer and an increased emphasis on the unit's 85db sound output establish peace of mind, while the inclusion of Dual Smoke and Carbon Monoxide Sensing all but guarantees the safest of experiences. This alarm carries a 7 year limited warranty and complies with UL217 and UL2034 Standards.

* California and New York Residents - Please note this alarm is not compliant with your state's 10 Year Sealed Battery Alarm Legislation Requirements.
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.

The package came blazingly fast! and I hadn't paid for expedited delivery, either!... The alarm was exactly what I was looking for just like the old one that died, so I'm very pleased.

Good Service and Product
The alarm went out the same day it was ordered and works properly so far. The only downside is a small box would have been better for shipping than the plastic envelope it came in, in order to prevent shipping damage. The small piece of plastic with the batteries was crushed.

These are great overall, my one small complaints is that when testing them, it's sometimes hard to press the button. But overall highly recommended.
