Q:How do I deactivate the alarm. It is beeping and there is no smoke. Alarm is just a few months installed
by|Nov 7, 2023
1 Answer
Answer This Question

A:  Hello. The alarm can be deactivated on the back. To Permanently Disable Alarm / Discharge Battery, push in the dashed area with a screwdriver to completely break tab. After the tab is broken, use the screwdriver to break through the label and turn the slotted arrow counter clockwise to the “PERMANENTLY DISABLE and DISCHARGE alarm” location. This will disable the alarm, stop the low battery or end of unit life "chirps" and render the alarm safe for disposal by draining the battery. If you have issues with our alarms again, please call us at 1-800-880-6788 while onsite with the alarms before you replace them. We do stand behind our products and we are happy to troubleshoot and figure out what is going on and get an issue resolved. False alarms are most commonly caused by something interfering with the sensor. To clean the alarm, hold the unit by its edge and thoroughly blow through the gap on the side of the unit with compressed air (like keyboard cleaner). We recommend cleaning out all of your smoke alarms at least every 6 months to a year and at this point we would recommend cleaning out all of your other alarms as well as a preventative. Some of your alarms may be in one the locations to avoid listed in the owner's manuals. This would especially include alarms being installed within 3 ft (.9m) of a forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. We recommend that alarms not be installed near vents, flues, chimneys, or fans. We recommend that alarms not be installed near doors or windows near areas directly exposed to the weather. We strongly recommend not to install these alarms in garages, attics, and crawl spaces as you will get temperatures, dust, insects, and chemicals that can cause nuisance alarms. Try cleaning out the alarms. If you have the issue again, find the alarm setting off all of the others and call us with that alarm in hand at 1-800-880-6788 so we can get this resolved for you. •

      Q:What makes this version “Ideal for Kitchens”?

      Answer This Question

      A:  Hello. The Kidde P3010K-CO is a 10-year, sealed battery, smoke and carbon monoxide alarm that features photoelectric and electrochemical sensing technology with Smart Hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with that of an electrochemical sensor, which is used to detect CO. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm’s overall performance and significantly reduces the potential for a nuisance alarm.

        Answer This Question

        A:  Hello. This unit has a photoelectric sensor that uses light to detect smoke and is less likely to be affected by steam, heat, and humidity although enough steam directly into the alarm or enough moisture to condense in the alarm will set it off. In addition, the Kidde P3010K-CO is a 10-year, sealed battery, smoke and carbon monoxide alarm that features photoelectric and electrochemical sensing technology with Smart Hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with that of an electrochemical sensor, which is used to detect CO.

                      Q:Where should hang dis one close to the kitchen r wut ?

                      1 Answer
                      Answer This Question

                      A:  Actually, no, not if it is your only alarm. We recommend that smoke alarms go in the immediate area of the sleeping rooms or bedrooms or any rooms where anyone sleeps. We recommend monitoring the exit path from the sleeping rooms to outside. Additional alarms can be put in the sleeping rooms themselves. We recommend at least one alarm on every floor level. If you only have one alarm, it should go near the bedrooms.
