        The product claims to meet meet UL 217 and UL 2034 standards. However, the manual shows only the ETL report number. The UL numbers are not printed on the device, which is required in Pennsylvania. Are these certified, and why is that not on the label?

          Answer This Question

          The alarm does not beep periodically during normal standby. It only beeps when testing, in alarm, or if there is a low battery or fault condition. If you hear occasional beeps, please check the LED light indicate low battery or sensor error. You can press the TEST/SILENCE button once to temporarily silence the beep.

            good dual alarm detector
            This detector is slightly larger than usual. It has both smoke and carbon monoxide alarm. The alarm is fairly loud, for both detected. It takes a little while to find the battery compartment and how to open it. I used a small flat screwdriver to gently pry the cover outward. Connecting is fairly straightforward. One side has a tail that plugs into the body and the other one three color-coded wires that connect to the hardwired wires. It attached with regular connectors. I am still trying to figure out how to add additional detectors to connect them.

            Quality dual detectors with a fashionable look
            This is a four pack of quality brand name smoke and carbon monoxide detectors that are hard-wired with a battery backup. It is recommended that a licensed electrician install the detectors. They come with two-wire set up, with a third wire option. The battery installation was exceedingly difficult, it was hard to open the latch, but once the battery is put in the latch closed in a normal operation.

            Good Quality Smoke And Carbon Monoxide Detectors
            My existing smoke alarms were in need of replacement so I was very happy to get these. As a bonus they detect carbon monoxide as well which my existing ones did not. They were packed well and included dust covers and six AA batteries. There should have been eight however. Installation was easy and took about ten minutes. They have hush buttons too.

            Smoke and Carbon Monoxide Detector
            Replacing all my old smoke detector with these. Love the upgrade from just smoke to carbon monoxide AND smoke! Big step up for safety! They are slightly deeper than our old ones but once installed it is not really noticeable .Very nice sleek design looks clean. Most of our appliances/heater/water heater are gas which we love but this gives us that extra layer of security!

            They work and are simple to install
            This 4 pack of hardwired, connected smoke and carbon monoxide detectors are nicely packaged and come with everything needed to install to your existing wiring. Each unit was individually wrapped and even comes with a plastic dust cover, similar to a shower cap. These are a nice accessary to have for times you may have a dusty project, such as drywall or tile work that creates dust. These covers will help protect the detectors. Another nice feature is the battery backup are 2 AA batteries compared to 9 volt batteries. We always have AA on hand but many times we found we were out of 9 volts when the unit started chirping in the middle of the night. These install quickly and smoothly utilizing the included wiring harness which then connects into the unit. After you connect all the wires in the electrical box, pull the connector that will attach to the smoke alarm through the mounting bracket hole, then attach the mounting ring to the electrical box with 2 screws. Align the smoke alarm on the mounting bracket and twist about a quarter of a turn and they are set. A steady green light displays the unit has power. Press the test button to ensure all go off (if you interconnected with other units), and you are done.

            Low quality sensors
            We installed 4 of these detectors. 3 of them started malfunctioning within a few weeks of installation. Would not reset, kept on going. HD had an "oh yeah??" attitude. Didn't believe the level of malfunction. Funny enough they still kept on going as I drove them to Home Depot (wrapped in bubble wrap so my ear drums wouldn't pop), and they STILL didn't quite believe me!! They wouldn't accept a return because it was outside the 90 days. As I left they were still going as the employee plopped them in the return bin.

              Purchased because I was looking for Smoke, Fire, and Carbon Monoxide detection included in one unit with voice alert. The fact I could buy 4 in bulk also saved me quite a bit if money. Simple installation.
