Tips For Troubleshooting Your Home Alarm System In San Bernadino

False alarms and system hiccups can be exasperating, and more importantly, could prevent your home’s security from doing its job effectively. Fortunately, most problems, from false alarms to dead batteries, are simple to fix. Take a look at our suggestions for troubleshooting your home alarm system in San Bernadino. We’ll help you keep your family members safeguarded and your system operating smoothly.

Test Your Home Security System In San Bernadino

One of the most sensible ways to troubleshoot your property’s security is to test it! The latest systems have a test mode so you don’t mistakenly prompt an emergency response. Once in test mode, take these steps:

  • Arm your system as you would when you exit your home.
  • Open a door or window protected by a contact sensor, or try to trip another sensor. Close the door or window once you’re finished so it doesn’t trigger the alarm when you switch the system back on.
  • Permit the alarm to go off for 60 seconds to make sure a signal is sent to the security provider and an entry is made in the alarm activity log.
  • Continue testing sensors as needed
  • Review the systems’s activity log to confirm that everything’s working.

Rest assured, monitoring agents will be aware that your system is being tested. Just make sure to switch out of test mode when complete. It’s wise to test once a month or whenever you make changes to your home’s internet or phone provider.

Inspect The Position And State Of Motion Detectors

Although an crucial part of your alarm system, motion sensors are notorious for false alarms. Prevent them with a few basic troubleshooting steps.

  • Perform a visual inspection. Are there items that could shift within the sensor’s detection range, like a window treatment taken by a breeze?
  • Is the sensor covered in dust? Dirt, cobwebs, and debris can result in issues. Make sure the sensor is clean.
  • Does the motion detector have pet immunity you can enable? Some models can be programmed to disregard pets up to 100 pounds.
  • When was the battery changed? Low batteries might impact performance or result in false alarms.
  • Is the sensor pointing toward a heat source? Too much heat from a fireplace, direct sun, or something else can trigger an alarm.

Keep Batteries Ready And Pay Attention To Low Battery Warnings

One of the great things about new home security systems is that they’ll alert you when batteries are running low. If your system has a control panel or mobile app, you’ll usually see notifications there. Depending on your alarm, you might hear an occasional beep when batteries are low. 

Contact sensors, smoke detectors, motion sensors, and other wireless tools have batteries that need to be replaced every 1 to 2 years. It’s wise to keep batteries on hand and create a replacement schedule. Some systems also include a backup battery for the primary control panel. This backup battery keeps your system functioning if you lose power and should recharge once power is restored. If it doesn’t recharge, you will need to replace it.
