Step 2: To adjust the smoke detector sensitivity, first of all, remove the screw from the smoke alarm system using a screwdriver. The detector's on-board microprocessor measures and analyzes these signals. This threshold is at a sensitivity level This pre-emptive warning provides the time necessary to take corrective action and avoid the danger that a fire can cause. If a smoke detector is not as sensitive as it should be, then it may not react as quickly as it should to a fire. The same detector showed the sensitivity value of 3.2%/m by the filter paper of the Japanese standard.
