Tips For Troubleshooting Your Home Alarm System In Louisville

System glitches and false alarms can be aggravating, and more importantly, could prevent your home’s security from doing its job effectively. Thankfully, most problems, from dead batteries to false alarms, are straightforward to fix. Check out our recommendations for troubleshooting your home alarm system in Louisville. We’ll help you keep your family safe and your system operating properly.

Test Your Home Security System In Louisville

One sensible way to troubleshoot your property’s defense is to test it yourself! Modern systems let you place them in test mode to prevent you from initiating an emergency call. After moving to test mode, follow these steps:

  • Activate your system as you normally would when you head out.
  • Open a door or window that has a contact sensor, or try to trigger another device. Close the window or door once you’re finished so it doesn’t trigger the alarm when you reactivate the system.
  • Let the alarm resonate for 60 seconds to ensure communications with the security provider and to produce an entry in the alarm system log.
  • Proceed to test sensors as needed
  • Check the system activity log to verify proper function.

Rest assured, monitoring specialists can see that your alarm system is involved in a test. Be sure to switch off test mode when you’re done. It’s a good idea to test once a month or anytime you make changes to your home’s internet or phone service.

Check The Positioning And State Of Motion Detectors

Although an crucial part of your alarm system, motion sensors are prone to false alarms. Prevent them with some easy troubleshooting.

  • Do a visual check. Are there items that could shift within the sensor’s detection range, like drapery taken by a breeze?
  • Is the sensor dirty? Grime, dirt, and cobwebs can result in poor performance. Make sure the face is clean.
  • Does the motion detector have pet immunity you can enable? Some models can be configured to ignore pets weighing up to 100 pounds.
  • When was the battery replaced? Low batteries might impact performance or cause false alarms.
  • Is the sensor aimed toward a source of heat? Too much heat from a fireplace, direct sun, or something else can trigger an alarm.

Keep Batteries Ready And Watch Out For Low Battery Warnings

One of the great things about modern home security systems is that they’ll alert you when batteries are dying. If your system uses a control panel or mobile app, you’ll typically discover messages there. Depending on your alarm, you might detect an intermittent beep when batteries are low. 

Motion detectors, smoke detectors, contact sensors, and other wireless components have batteries that should be replaced every so often. It’s a good idea to keep batteries around and set a replacement schedule. Some systems also have a backup battery for the primary control panel. This backup battery keeps your system functioning if you lose power and should recharge once the electricity is working again. If it doesn’t, you will have to replace it.
