What Does The Yellow Triangle Mean On My ADT DSC Impassa Alarm system

Do you own an ADT DSC Impassa alarm system, and have you noticed a yellow triangle symbol on your DSC ADT Alarm system? Is your system beeping twice every 10 seconds?

You may be wondering what it exactly means. No worries, we have the answers! 

Let’s quickly discuss what the appearance of this yellow shape means and what you need to do.

What It Means & How to Fix It-

Let’s get straight to it!

A yellow triangle on your DSC ADT Alarm system is also known as a “trouble light.” That means if you see this symbol, your system has an issue that you need to resolve. 

A trouble light could mean 1 of 8 problems. To find out what the problem is, you can simply press *2 on your keypad. After pressing this on the keypad, your zone lights should light up, communicating any trouble areas. Pushing # will silence the trouble sound. Then here’s a quick look at what your yellow triangle could be telling you:

  1. AC Power Loss – You’ve lost power. You’ll know this because the keypad will not make a beeping sound, but it will be lit up. Check the outlet where you plugged in your system. 
  2. Low Battery – One of your zones is currently running on a low battery. (If you’re looking for a replacement battery, search no further. Go ahead and click here.)
  3. Phone Connection – There could be a problem with the telephone line.
  4. Communication Fault – The panel and central station aren’t communicating properly. (Call and perform a test at 1-800-238-2727.)
  5. Zone is open – There is an issue with a zone. You can press 5 on the keypad to see which zone is currently experiencing an issue.
  6. Zone Tamper – One of your zones has been meddled with. You can press 6 on the keypad to figure out which zones you need to address.
  7. Time and Date – Your system clock is messed up. Just update to the correct time and date. 
  8. You might need to call ADT Customer Service to resolve the issue. 1-800-238-2727

As you can see, you’ll be able to fix a majority of these problems without help, but if you need ADT Customer Service, call them at 1-800-238-2727. If they didn’t answer your question, or you need extra help, feel free to give us a call here: 1-800-871-2119.

      I recommend you test your system with the monitoring station if the communication trouble is still on there.

      To change the time on the clock on the DSC Impassa you just need to press *6-Mastercode-1. Then enter HH:MM and MM/DD/YY. Then press # when you are done. You need to enter military time (example 8pm = 20:00 hours)

      I would check and make sure you know where it is and make sure it has new batteries. If those are ok, then I would replace it.

      It should clear on its own if you solved the issue, if you are seem to be running into a wall with the issue please call the monitoring station and see if they can provide additional insight as to what it could be.

    After i click *2 to read the message, there is no message present. It just says to hit # to exit the screen. After I do that, the trouble light stays yellow so I dont know what the exact issue is.

      If it is not showing you what is causing the trouble light I recommend you call the monitoring station so they can help you troubleshoot it.

    So how do you clear the yellow triangle

      It just depends that the issue is that the keypad is telling you. If its a battery, than get a new system battery or sensor battery. https://zionssecurity.com/product-category/batteries/

      If its an issue with a sensor being tampered with or open than check that zone. It could be a communication problem with the monitoring station, so call and test your system, etc… So just look into it and if you need help let us know or call the monitoring station.

      Monitoring service does not expire, but if you cancel your service you will get an error from lack of communication

      You would need to check why the system is beeping? Is it a low battery? Is it because the communication is cut off? You will likely need a technician or phone tech support to change the settings in your system so it is not looking for the monitoring service still.

    The yellow alarm notification is on and says displays the problem area. I go to that window and its closed. I never open it and I’m not on the ground level, so it wasn’t tampered with.

      Is the magnet still there lined up where it should be? Maybe it got bumped and is making the window show open because the magnet needs better alignment?

      After replacing the battery, try arming and disarming the panel. If the alert still doesn’t clear, give the battery about 24 hours to recharge then try arming/disarming again to see if it clears after that. If you’re still showing the alert, please let us know.

      Try to find out why it was beeping. You can push *2 and and use the arrows to try and see if it was a communication loss or a low battery etc…Then let us know if we can help you with the issue.
