Tips For Troubleshooting Your Home Alarm System In St. Louis

System glitches and false alarms can be frustrating, and even worse, may prevent your home’s security from working how it should. Luckily, most issues, from dead batteries to false alarms, are straightforward to remedy. Explore our suggestions for troubleshooting your home alarm system in St. Louis. We’ll help you keep your family members safeguarded and your system operating smoothly.

Test Your Home Security System In St. Louis

One great way to troubleshoot your property’s security is to test it yourself! Modern systems let you put them in test mode to prevent you from initiating an emergency response from monitoring agents. After switching to test mode, take these steps:

  • Arm your system as you would when you leave.
  • Open a door or window that uses a contact sensor, or try to set off another device. Shut the door or window once you’re finished so it doesn’t trip the alarm when you switch the system back on.
  • Permit the alarm to sound for 60 seconds to ensure communications with the security company and to create an entry in the alarm activity log.
  • Proceed to test equipment as you wish
  • Inspect the alarm’s activity log to verify functionality.

No need to worry, monitoring professionals will know that your system is involved in a test. Just be sure to switch off test mode when done. It’s wise to test monthly or anytime you adjust your home’s phone or internet provider.

Evaluate The Positioning And Condition Of Motion Detectors

Although an integral aspect of your alarm system, motion detectors are notorious for false alarms. You can help prevent them with a few basic troubleshooting steps.

  • Conduct a visual check. Is there something that could shift within range of the sensor, like a window treatment blown in a breeze?
  • Is the sensor clean? Dirt, cobwebs, and debris can result in issues. Make sure the sensor is clean.
  • Does the motion detector have pet immunity you can activate? Some sensors can be set to ignore pets weighing up to 100 pounds.
  • When was the battery last replaced? A low battery can affect performance or cause false alarms.
  • Is a heat source impairing the sensor? Too much heat from direct sun or a fireplace can trigger an alarm.

Keep Batteries Ready And Watch Out For Low Battery Signals

One helpful benefit of new home security systems is that they’ll tell you when batteries are dying. If your system is equipped with a control panel or app, you’ll typically find messages there. Depending on your system, you may hear an intermittent beep when batteries are low. 

Contact sensors, smoke detectors, motion sensors, and other wireless tools have batteries that should be replaced every so often. It’s best to keep batteries ready and set a replacement schedule. Some systems also come with a backup battery for the primary control panel. This backup battery keeps your system operating if your power goes out and should recharge once the electricity is working again. If it doesn’t, you will need to replace it.
