Tips For Troubleshooting Your Home Alarm System In Nashville

False alarms and system hiccups can be frustrating, and even worse, might prevent your home security system from doing its job effectively. Thankfully, most problems, from false alarms to dead batteries, are straightforward to fix. Take a look at our suggestions for troubleshooting your home alarm system in Nashville. We’ll help you keep your household protected and your system operating smoothly.

Test Your Home Security System In Nashville

One of the most effective ways to troubleshoot your property’s security is to test it! The latest systems have a test mode so you don’t by accident initiate an emergency response. Once you’re in test mode, follow these steps:

  • Arm your system as you typically would when you head out.
  • Open a window or door that has a contact sensor, or test other devices. Shut the window or door once you’re done so it doesn’t prompt the alarm as you switch the system back on.
  • Allow the alarm to sound for 60 seconds to ensure communications with the security company and to make an entry in the alarm activity log.
  • Continue testing equipment as needed
  • Inspect the alarm’s activity log to verify functionality.

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

Evaluate The Positioning And State Of Motion Detectors

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

  • Perform a physical check. Are there things that could shift within the sensor’s detection range, like a curtain caught in a breeze?
  • Is the sensor covered in dust? Cobwebs, dirt, and debris can cause issues. Ensure the sensor is clean.
  • Does the motion detector offer pet immunity you can enable? Some can be set to disregard pets weighing up to 100 pounds.
  • When was the battery last replaced? A nearly depleted battery may affect performance or result in false alarms.
  • Is a heat source impairing the sensor? Excessive heat from a fireplace, direct sun, or something else can cause an alarm.

Keep Batteries On Hand And Pay Attention To Low Battery Notifications

One of the great aspects of the latest home security systems is that they’ll let you know when batteries are running low. If your system is equipped with a smartphone app or control panel, you’ll often discover alerts there. Depending on your system, you might hear an occasional beep when batteries are low. 

Motion sensors, contact sensors, smoke detectors, and other wireless tools have batteries that need to be replaced every 1 to 2 years. It’s a good idea to keep batteries around and create a replacement schedule. Some systems also include a backup battery for the main control panel. This battery keeps your system running if you lose power and should recharge itself once the electricity is working again. If it fails to recharge, you will have to replace it.
