Why is my DSC NEO keypad beeping and what does the yellow triangle mean?

<Back

 If your keypad is beeping or has the yellow triangle lit up this means that there is some kind of system trouble. This can be something as simple as a low battery, and usually is, or it could be something more serious such as a system tamper. Depending on the style of keypad that you have the steps you’ll take will be slightly different. Once you know what troubles/codes the system is giving you, you can go to the PowerSeries NEO reference manual for troubleshooting steps. The troubleshooting guide is Section 7.

With an LCD style keypad, press *2. The screen will display a trouble and you’ll be able to either press * to learn more in depth information about that trouble or scroll to see if there are any other troubles.

With an ICON style keypad, you will also press *2. Instead of getting specific info, you will get a number or numbers displayed on the screen that correspond to a trouble type. You can then press the number on the keypad to go deeper into the specifics of the trouble. You will need to use the reference manual to determine what exactly those numbers mean.

With a touchscreen keypad it is fairly intuitive. There is a button that looks like a triangle with an exclamation mark inside. When you press that it will show the various trouble conditions and if necessary you can touch those for more information.
