Tips For Troubleshooting Your Home Alarm System In Long Beach

System glitches and false alarms can be exasperating, and more importantly, may prevent your security system from working how it should. Thankfully, most issues, from false alarms to dead batteries, are easy to remedy. Explore our recommendations for troubleshooting your home alarm system in Long Beach. We’ll help keep your family shielded and your system operating properly.

Test Your Home Security System In Long Beach

One sensible way to troubleshoot your property’s defense is to test it! The latest systems let you place them in test mode to keep you from triggering an emergency response from monitoring agents. Once in test mode, do the following:

  • Arm your system as you would when leaving.
  • Open a door or window protected by a contact sensor, or test other devices. Shut the window or door once you’re finished so it doesn’t prompt the alarm as you reactivate the system.
  • Let the alarm go off for 60 seconds to make sure a message is sent to the security provider and an entry is made in the alarm system log.
  • Continue testing sensors as needed
  • Review the systems’s activity log to validate proper function.

Don’t worry, monitoring professionals will be able to see that your alarm system is involved in a test. Just be sure to switch out of test mode when complete. It’s wise to test monthly or anytime you change your home’s phone or internet provider.

Evaluate The Positioning And Condition Of Motion Detectors

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

  • Conduct a physical check. Are there objects that could shift within the sensor’s detection range, like drapery caught in a breeze?
  • Is the sensor clean? Dirt, cobwebs, and debris can result in poor performance. Ensure the face is clean.
  • Does the motion detector offer pet immunity you can activate? Some can be set to ignore pets weighing up to 100 pounds.
  • When was the battery changed? Low batteries might affect performance or result in false alarms.
  • Is the sensor facing a heat source? Excess heat from sunlight or a fireplace can cause an alarm.

Keep Batteries On Hand And Watch Out For Low Battery Signals

One of the great aspects of new home security systems is that they’ll alert you when batteries are dying. If your system has a mobile app or control panel, you’ll typically see alerts there. Depending on your alarm, you could hear an occasional beep when batteries are low. 

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