        Answer This Question

        A:  Hello. It could be the unit is going into an error mode either due to an issue with the alarm or because it has debris in the smoke chamber. Try blowing out the alarm very well with compressed air around the back side edges of the alarm. If that doesn't resolve the issue, please call us with the alarm in hand at 1-800-880-6788 so we can get that resolved for you.

                  Q:Does this type of alarm/detector have to be hardwired or would battery operated be sufficient?
                  by|Nov 18, 2023
                  1 Answer
                  Answer This Question

                  A:  Hello. This alarm is battery only and can not be wired in. Check with your local authority requiring smoke alarms to find out exactly what kind of smoke alarms you are required to have and where you are required to have them. This is usually your local fire department, local fire marshal's office, or local town government.

                    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. •
