                Frequently Asked Questions

                hide show

                What causes the smoke alarm to continuously beep ?

                The dust inside the smoke alarms can cause a continuous beep.
                Please follow the regular maintenance check to avoid this.

                Vacuum the smoke alarms using a soft brush attachment-
                Keeping your smoke alarm free of dust particles, dirt, kitchen grease or cobwebs will help you reduce false alarms and ensure any smoke can easily reach the internal sensing chamber.

                Clean and wipe down around unit-
                Clean around the smoke alarm unit and remove any insects or other contamination which may have occurred. Spray bug repellent on a cloth and wipe the ceiling around the smoke alarm to act as a future bug deterrent. Clean every 3-6 months to mitigate insect ingress.
