Home alarms have one important job: to alert you of possible trouble. While you’re glad to have peace of mind, those shrill, beeping alarms can also become a nuisance. If you have alarms that seem to go off for no reason, here are four steps to track down what’s going on:

Note: If your fire alarm keeps going off please replace the batteries or the unit.

Locate Pets or Small Children

Your toddler or family dog may have wandered somewhere he shouldn’t have and tripped one of your alarm features. This can be annoying, but it also creates an excellent opportunity for you to update your home security. You can teach your kids about home safety or set up barriers to keep pets from crossing the sensors and wandering away.

Pet-Friendly Motion Detectors

Pet owners will be happy to know there are pet-friendly motion detectors available on the market. This security equipment can disregard movement from animals weighing less than 40 pounds.

If you’re ready to bring the irritating false alarms to an end, then it’s time to look into pet-friendly detectors. It’s too risky to avoid setting your alarm altogether just to avoid the loud beeping sound. This makes it easier for unwanted guests to enter your home undetected. Instead, seek guidance from security experts on navigating the right pet-friendly motion detector for your home. Protect America’s award-winning home security equipment includes wireless and intelligent motion sensors that provide up to 25 feet of horizontal coverage. These sensors are easy to self-install with mounting adhesives… and the best part is-they’re pet immune to most animals weighing under 40 pounds.

Check For Dead Batteries

A dead battery in one of your components creates a gap in your home security system. Some systems will react to that by setting off an alarm, alerting you to potential problems. Other home security components may sound an alarm when the battery gets low. This is the case for some fire alarms, for example. Working fire alarms are one of the most important investments you can make for your family’s safety.

Smoke alarms, properly installed and maintained, play a vital role in reducing fire deaths and injuries. If there’s a fire in your home, smoke spreads fast and you need smoke alarms to give you time to get out.

Tips for Changing Batteries in a Smoke Alarm

If a dead battery is the main culprit behind why your home alarm goes off for no reason, you’re going to want to know how to change the batteries. Most importantly, you’re going to want to know how to change the batteries safely and efficiently. Here are some easy-to-follow steps for getting the job done:

  1. Find a ladder that is stable enough to reach your smoke alarm
  2. Twist or pull open your smoke alarm. In some cases, you will need a screwdriver to pry open your detector
    Remove the old battery
  3. Place in the new battery. Make sure the negative and positive connections are matching the connections in the smoke alarm
  4. Locate and press the test button to make sure the new batteries work

Keep in mind that the most common smoke alarms are battery smoke detectors and hardwired smoke detectors. Battery smoke detectors run on batteries. Hardwired smoke detectors, on the other hand, run on electricity and have constant power unless there is an outage. This is when a backup battery comes into play.

It’s vital to replace the batteries in your security system components regularly. Not sure where to find replacements? Some batteries can’t just be picked up at the local hardware store, so we’ve created a guide to buying home alarm batteries.

Have Your Sensors Checked

If your sensors were installed incorrectly or in a poor location, or if you’ve made major changes to landscaping and household decoration, then they may trigger ‘for no reason’ now. For instance, sensors installed near a furnace in the summer may act normally, but in the winter sophisticated and highly sensitive products may be triggered by the heat and moving air. A security expert can assess what is happening and why and make adjustments.

Home Alarm Goes Off For No Reason: Search for Signs of Wear and Tear

Even a quality, properly installed security system can start to fail if components become weathered and worn out. This can happen for both indoor and outdoor security systems. Take a look around your house and keep an eye out for:

  • cracked or rusted component housing
  • charred or frayed wiring
  • signs of leaking batteries
  • a unit dangling from its mounting
  • dust and leaf buildup
