Follow these steps to work out what&#8217;s going on.<\/p><p><b>First, check there&#8217;s no smoke or fire in your property.<\/b><\/p><p>If there&#8217;s no fire, look into these common causes:<\/p><p><b>Could it be another alarm?<\/b> Make sure the beeping is definitely coming from your smoke alarm. Other alarms in your home, such as a carbon monoxide alarm or burglar alarm, could be making the noise.<\/p><p><b>Is dust or dirt setting it off?<\/b> Give the alarm a clean if it&#8217;s dusty or dirty. Vacuum around the alarm or use a hairdryer on a cool setting to blow out any dust from the sensor chamber.<\/p><p><b>Has your smoke alarm reached its expiry date?<\/b> Check the &#8220;replace by&#8221; or manufacture date on the back of your alarm. Smoke alarms last a maximum of 10 years. If the manufacturing date is approaching or past 10 years, it&#8217;s time for a new one. The sensors inside deteriorate after this point, making the alarm less effective at detecting fires.<\/p><p><b>Is your alarm in the wrong spot?<\/b> Different sensor types work best in different locations. An optical smoke alarm in a kitchen, for example, may go off from cooking fumes.<\/p><p><b>Could the alarm be damaged or faulty?<\/b> Water, fire, grease and certain paints can all cause faults. If you think there&#8217;s damage,<a href=\"https:\/\/www.safelincs.co.uk\/replacement-smoke-and-heat-alarms\/\"> replace your smoke alarm<\/a> straight away to keep your home and family safe.&nbsp;&nbsp;<\/p>\n      <\/div>\n    <\/div>\n  <\/div>\n  <!-- Close Image + Text Block -->\n\n  <!-- Open Rich Text Block -->\n  <div style=\"padding: 0px; margin: 10px 0; border-width: 0px; border-color: #000000; border-style: solid; border-radius: 0px; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; text-align: left\"><h2>Why Is My Battery Smoke Alarm Chirping Intermittently?<\/h2><p>An intermittent chirp or beep (typically once every 30 to 60 seconds) almost always means a low battery. Here&#8217;s what to do.<\/p><p><b>Replace the battery.<\/b> Make sure you&#8217;re using the right battery type and inserting it the right way round. A low battery is more likely to sound at night because a drop in room temperature reduces its ability to power the alarm.<\/p><p><b>Check how old your alarm is.<\/b> Smoke alarms last a maximum of 10 years. If the manufacturing date on yours is approaching or past 10 years, it&#8217;s time for a replacement. Even with a fresh battery, an old alarm may chirp because the sensors are wearing out.<\/p><p><b>Look for signs of damage.<\/b> Water, fire, grease and certain paints can cause faults.
