Tips For Troubleshooting Your Home Alarm System In Elizabethtown

System hiccups and false alarms can be frustrating, and more importantly, may prevent your security system from working how it should. Fortunately, most troubles, from false alarms to dead batteries, are simple to fix. Explore our recommendations for troubleshooting your home alarm system in Elizabethtown. We’ll help keep your family protected and your system running the way it should.

Test Your Home Security System In Elizabethtown

One of the best ways to troubleshoot your property’s defense is to test it yourself! Newer systems have a test mode so you don’t accidentally prompt an emergency call. Once you’re in test mode, take these steps:

  • Arm your system as you typically would when heading out.
  • Open a window or door protected by a contact sensor, or test other devices. Shut the door or window so it doesn’t prompt the alarm when you switch out of test mode.
  • Allow the alarm to go off for 60 seconds to make sure a transmission is sent to the security provider and an entry is made in the alarm activity log.
  • Continue testing equipment as you wish
  • Check the systems’s activity log to confirm proper function.

Rest assured, monitoring specialists will be able to see that your system is involved in a test. Just be sure to switch off test mode when you’re done. It’s smart to test every other month or anytime you adjust your home’s internet or phone connectivity.

Check The Positioning And Condition Of Motion Sensors

Although an crucial part of your alarm system, motion detectors are notorious for false alarms. Do your part to prevent them with a few straightforward troubleshooting steps.

  • Conduct a physical check. Are there things that could move within the sensor’s detection area, like a window treatment taken by a breeze?
  • Is the sensor dirty? Cobwebs, dirt, and debris can cause poor performance. Check to confirm the face is clean.
  • Does the motion detector have pet immunity you can turn on? Some sensors can be programmed to disregard pets weighing up to 100 pounds.
  • When was the battery changed? A low battery might impact performance or result in false alarms.
  • Is a heat source impacting the sensor? Excessive heat from sunlight or a fireplace can trigger an alarm.

Keep Batteries On Hand And Pay Attention To Low Battery Signals

One helpful benefit of modern home security systems is that they’ll tell you when batteries are getting low. If your system has a control panel or mobile app, you’ll usually discover messages there. Depending on your system, you might detect an occasional beep when batteries are low. 

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