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 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)
