Why is my DSC 1616, 1832, or 1864 system keypad beeping and what does the yellow triangle mean?

<Back

If your keypad is beeping or has the yellow triangle illuminated, that means that your system has a trouble condition. To find out exactly what it means, you’ll need to press *2 on a keypad. If you have a full message keypad such as a PK5500 keypad, the keypad will give you some information as to what the light means. You will just need to use the arrow keys to scroll through. Often you will then need to press * to go deeper as to the specific cause. With a PK5501, when you press *2 a number or multiple numbers will appear on the screen. These correspond to a trouble condition. As with a full message keypad you will often need to get more specific information by pressing the number of the trouble condition. The screen should show a new set of numbers that will give you more information.
