Product Description

Size: 1-Pack

The Kidde PI2010 Battery-Operated Dual Sensor Smoke Alarm combines photoelectric and ionization sensing technologies into one unit to offer broad detection against smoldering and flaming fires. Experts recommend that for optimal protection you have both types of sensing technology in your home. This smoke alarm's trademarked Hush feature allows you to silence nuisance alarms, while an indicator LED and test feature let you easily confirm that the alarm is working.

The Kidde PI2010 Smoke Alarm:
  • Employs both photoelectric and ionization sensors.
  • Features a hush button to silence the alarm for non-emergency situations like a smoky dinner.
  • Compact design blends in seamlessly with your home decor.
  • Wire-in smoke alarm with 9V battery backup.

With two different sensors, you'll get warnings sooner no matter the kind of fire. View larger.

Dual-Sensor Technology for Improved Safety
Experts divide home fires into two groups: flaming and smoldering. Flaming fires result from flammable liquids and cooking accidents, while smoldering fires most often occur when smoking materials, such as cigarettes, are left unattended. Ionization smoke sensors may detect smaller, less visible fire particles, like those produced by flaming fires, sooner than photoelectric sensors. However, photoelectric sensors are may detect larger, more visible fire particles, such as those produced by smoldering fires, sooner than ionization sensors. Each must pass identical performance standards to obtain third-party approval and meet Underwriters Laboratories (UL) 217, the independent standard to which alarms are listed. Because you don't know what type of fire you will have in your home, experts recommend installing both types of technology for optimal protection.

Experts Recommend Protection from Both Types of Fires
Virtually every recognized fire authority recommends the installation of both ionization and photoelectric alarms in order to maximize protection from either flaming or smoldering fires. Kidde offers photoelectric smoke alarms, ionization smoke alarms, and dual sensor alarms, which combine both technologies in one unit. Regardless of the technology, the most important thing is to ensure that you have working smoke alarms on every floor of your home, inside each bedroom and outside sleeping areas. Studies show placing alarms in both bedrooms and hallways could increase a family's escape time by up to 15 minutes.

Fire Authorities recommending both smoke alarm technologies:

  • National Fire Protection Association (NFPA)
  • International Association of Fire Chiefs (IAFC)
  • U.S. Fire Administration (USFA), the National Institute of Standards and Technology (NIST)
  • Consumer Product Safety Commission (CPSC)
  • Consumer Reports
  • National Association of State Fire Marshals (NASFM)
  • Underwriters Laboratory (UL)
  • 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 feature desensitizes the alarm for approximately seven minutes. During this time, the alarm chirps every 30 to 40 seconds. If the smoke is too dense, the Hush feature is overridden and the alarm still sounds, and the alarm automatically resets at the end of the seven minutes. This convenient safety measure eliminates the temptation to remove the alarm's battery, which creates an unsafe situation.

    Wire-in Smoke Alarm with Reliable 9-Volt Battery Backup, 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 30 to 40 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm contains a test/reset button that enables you to periodically test its circuitry and horn.

    The PI2010 is a wire-in smoke alarm with 9V battery backup, which provides 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 it's time to change the battery.

    The unit measures just 5.75 inches in diameter and 1.8 inches deep, and it features a neutral, white finish. It features tamper resist features to deter vandalism or theft.

    This dual-sensor smoke alarm is UL listed, so you can be confident of its quality, and it is backed by a 10-year limited warranty.

    The install was very easy and they seem to work fine.
    6 months later, one starts throwing false alarms at random times so I have to disconnect it.
    Unless this issue is corrected, I will not purchase another Kidde product.

    I didn't know about replacing smoke alarms every decade until very recently. The units in my home were two decades old, hardwired AC with no battery backup. They tested fine but after twenty years it is certainly time to replace them by any standard. There are three in my home, one on each floor.

    After doing a bit of research and being a smart consumer, I decided the PI2010 was the best choice out there. I purchased them up at a local big box home center because the price was highly competitive with Amazon and I didn't have to wait for shipping (even free super saver shipping).

    In the box was a mounting bracket, three-wire harness, instructions, screws, and the smoke alarm.

    Installation was a breeze - shut off the power at the circuit breaker first, removed the old alarms and harnesses next. The instructions with the PI2010 made it clear to not pull out the battery shipping tab until the units all had AC power applied. The mounting bracket was able to use the existing screws so I didn't have to even remove them from the ceiling box. The harness wired up easily and after plugging it into the alarm it only took a small twist to secure it to the mounting mounting bracket. After turning the power back on, I pulled the battery tabs out of each alarm. I tested each one, and had a friend make sure the units on the other floors sounded also.

    The alarms in this model are about twice as loud as my old smoke alarms, almost ear splitting loud so I believe there's no chance to sleep through it. A green LED tells you it has AC power and there is a red LED that flashes every so often to say it's working. I may find the 'hush' feature useful for my occasional kitchen disaster, but fanning a cookie sheet is my usual move when I burn something too crispy.

    The battery replacement is not nearly as bad as others have described. Just twist the unit off from the mounting bracket, pull off the wired plug, and flip open the battery case. I was also happy to learn that if your house has the red wire, all the smoke alarms are interconnected. That is, if one smoke alarm detects smoke, all the alarms in the house will signal an alert. HOWEVER, all the smoke alarms must be the same! That is, when I initially installed my first PI2010, it kept beeping 3 times every few seconds. I later found it's because I hadn't disconnected my old smoke alarm in the second area. Once I installed both PI2010s in my house, everything worked fine.

    Just bought a house and the smoke detector was over 20 years old. After looking at the various smoke detectors on the web, realized that I needed a dual alarm with both photoelectric and ionization sensors for best coverage. Most of the cheaper alarms are only ionization. This unit met my needs perfectly...

    Dual sensor
    Hard Wired (previous detector was hard wired)
    Battery Backup
    Hush button (for false alarms)

    Got the alarm a few days before the estimated arrival date. Pulled the pieces out of the box (instructions, bracket, unit, and wiring harness), did a quick look through the instructions and went to work. It really only took me about fifteen minutes to install...most of that time taking the old units bracket down and putting up the new one. The wiring harness has three, white and red...but the red one has a plastic cover over the end in case you don't need to wire multiple alarms together.

    After attaching the needed wires to the house electric with wirenuts and electrical tape, just attach the bracket to the wall, make the sure the included battery is isntalled in the unit, plug the wiring harness into the back of the unit and attach to bracket. Piece o' cake.

    If your home already has a certain wiring harness, and you don't want to mess with electrical, I believe there are adaptors available for the back of this unit as well that can accept other shaped harnesses. Very convenient, if you need them. For me, it was pretty simple to cut the power and hook it up myself.

    I bought two of these units when they first came out in early 2010. They replaced the origninal builder units which were way past the 10 year point that marks the lifespan of a smoke alarm (those builder installed units were not dual sensor models). The manufacture date on the back is Feb 2010 and they are the PI2010 model. This morning they both went off - they are interconnected of course - but no fire. There seems to be a pattern of failure on these Kidde units with dual sensors. I thought the PI2010 would be different - but in the end, they have failed as well as the non wired versions of these that I have also placed throughout my home where the builder did not wire for detectors (e.g. the bedrooms). Typically failure occurs within 1-2 years. At that point - you can try and dust them off with compressed air and reinstall them - but once they fail, they will false alarm over and over again. They are just trash at that point unless you want to work with Kidde customer service for replacements (which they will do for you - but you have to wait for them to come while unprotected).

    Kidde makes an excellent performing unit - the problem is that just don't last. As I said, they will send you replacement units (they have sent me 10+ units over the last few years and they all fail eventually). I want to be clear - I have the PI2010 which is this model and those are the ones that just failed today. However, I have come to the conclusion that the entire Kidde dual sensor line-up is junk due to the other models that have failed on me as well. I would not say this except for the fact I have had SO many failures over the past 5 years. I will be looking at other brands now - hopefully someone else makes a similar product that lasts. I expect to get the full 10 years out of these units.
