Description:


Combination Smoke and Carbon Monoxide Alarm 3-Pack
If you want to build an integrated smoke and carbon monoxide alarm system, but without the cost and hassle of retrofit wiring in your home, these combination smoke and carbon conoxide alarms are an ideal choice. These alarms provide ultimate protection from two deadly threats and they are packed with innovative features that give you precious time in the event of an emergency. And because they are able to wirelessly communicate with other, these alarms can help you create a whole-home safety network.
This model is battery operated, and batteries are included.


Faster Notification for Faster Escape
In the event of a fire or carbon monoxide (CO) emergency, every second counts. Unfortunately, traditional battery-operated alarms can often cost you precious time. For example, if a fire starts in your basement while you're asleep upstairs, you may not hear the smoke alarm, and it may take several minutes before the heat and smoke reaches an alarm that's close enough for you to hear its siren. Thankfully, wireless interconnect combination smoke and carbon monoxide alarms are designed to provide you the earliest warning in an emergency. When these clever alarms detect smoke or carbon monoxide, all integrated wireless interconnect alarms in your home will sound together, increasing your chances of getting out safely.

Interconnectivity Without the Wires
Until now, alarms that could signal each other were only available in homes with hardwired systems. All wireless interconnect alarms, however, communicate with each other wirelessly through integrated radio frequency. This means that when one sounds, they all sound, providing a whole-home safety network.


These Alarms Talk

First Alert voice smoke and carbon monoxide alarms tell you where the danger is to help your family make a safe escape. Indpendent studies show that children wake up to a voice alarm more than the standard beeping alarm.

I love how vague the negative reviewer is- "Instructions are not very clear and contradicted the First Alert help person. Never could get them set up properly, even with support help."

What would seal the deal for me is if these were dual sensors- photoelectric and ionization smoke sensors. This is only photoelectric.

Apparently these are First Alert SCO501CN-3ST [amazon.com]

what is better to have these days - photoelectric or ionization? or is the general consensus to have both so you are covered against slow smolders and aggressive flames? tia

Indeed both or a dual.

For others' knowledge-

Smoke Detector Sensors

Smoke alarms typically have three types of sensors: ionization, photoelectric, and dual. Here are the main differences between the three:

Photoelectric Sensors
Photoelectric sensors are better at detecting smoldering fires that generate lots of smoke. These sensors use a light to detect smoke and sound an alarm.

Ionization Sensors
Ionization sensors are designed to recognize fast-burning, flaming fires through the small amounts of smoke they produce. They're equipped with two metal plates and a small amount of radioactive material to ionize air. When smoke passes through the device, it interrupts the ionization and triggers the alarm.

Dual Sensors
Dual sensors include both photoelectric and ionization sensors. These are considered to be the safest smoke alarms because they detect both smoldering and flaming fires.

Something happened today that made me recall the placement of CO2 is important [sterlinghomeinspections.com] and why I'm not keen on combo units that are meant to be placed on the ceiling. I perfer to have around breathing level of adults and children. I had a new renter who called the gas company last week without informing me of her CO2 alarming sounding off from the water heater supposedly not venting properly. As it turned out it there was a bird's nest in the outside vent and also her stacked dryer which she had just venting lint into a waste basket. The previous renters only washed and air dried due to the utility room of this dated duplex being able to accommodate just a washer and the water heater.
