What is the keybus on a DSc powerseries panel?
In a lot of literature that talks about the DSC PowerSeries panels, you will see the word ‘keybus’ but you may not really get a good explanation as to what that means or what significance it has. The keybus is a 4-wire connection that is used for keypads and other modules.
What happens if the main board loses communication with the keybus?
If at any point the main board loses communication with a module or keypad on the keybus you will get a supervision trouble condition. You can then go and find what the issue is and resolve it. Or if you purposefully took something off of the system you will need to reset the keybus supervision in programming using section 902.
What are the yellow terminals on a DSc PC?
The Yellow and Green terminals are the data out and data in terminals. This is how the main alarm circuit board and other connected devices communicate back and forth with each other. The keybus is supervised as well. This means that anything connected to the keybus is detected by the main board and then saved.
What’s the minimum wire gauge for a DSc keybus?
DSC recommends that the minimum wire gauge to use is 22 while the maximum is 18 gauge. They also state that shielded wire should not be used for the keybus. Modules on the keybus can all be on home runs to the panel or connected in a parallel series or T-tapped. Or any combination of those wiring options.
