Tips For Troubleshooting Your Home Alarm System In Fresno

System malfunctions and false alarms can be frustrating, and even more concerning, could prevent your home security system from working how it should. Luckily, most issues, from false alarms to dead batteries, are straightforward to correct. Check out our tips for troubleshooting your home alarm system in Fresno. We’ll help keep your family members protected and your system operating smoothly.

Test Your Home Security System In Fresno

One of the best ways to troubleshoot your property’s security is to test it! Modern systems let you place them in test mode to keep you from triggering an emergency response from monitoring agents. After moving to test mode, take these steps:

  • Turn on your system as you normally would when you exit your home.
  • Open a door or window that has a contact sensor, or test other equipment. Shut the window or door so it doesn’t trip the alarm as you leave test mode.
  • Allow the alarm to go off for 60 seconds to make sure a signal is delivered to the security provider and an entry is made in the alarm system log.
  • Proceed to test devices as needed
  • Review the alarm’s activity log to validate functionality.

Rest assured, monitoring specialists will be aware that your alarm system is involved in a test. Just be sure to switch out of test mode when you’re done. It’s smart to test once a month or whenever you make changes to your home’s internet or phone service.

Evaluate The Positioning And Condition Of Motion Sensors

Although an crucial element of your alarm system, motion detectors are well known for false alarms. Prevent them with a few straightforward troubleshooting steps.

  • Do a visual check. Are there objects that could move within the sensor’s detection area, like a window treatment taken by a breeze?
  • Is the sensor dirty? Grime, dirt, and cobwebs can lead to malfunctions. Make sure the sensor is clean.
  • Does the motion detector offer pet immunity you can enable? Some sensors can be programmed to ignore pets weighing up to 100 pounds.
  • When was the battery changed? Low batteries can affect performance or cause false alarms.
  • Is the sensor facing a source of heat? Too much heat from sunlight or a fireplace can cause an alarm.

Keep Batteries Ready And Look Out For Low Battery Signals

One of the great aspects of modern home security systems is that they’ll tell you when batteries are running low. If your system has a control panel or app, you’ll typically find messages there. Depending on the alarm, you could notice an intermittent beep when batteries are running out. 

Motion detectors, smoke detectors, contact sensors, and other wireless components have batteries that need to be replaced every 1 to 2 years. It’s best to keep batteries ready and establish a replacement schedule. Many systems also have a rechargeable backup battery for the central control panel. This backup keeps your system running if your power goes out and should recharge itself once the electricity is working again. If it doesn’t recharge, you will have to replace it.
