Zones
The panel comes with factory programmed onboard hardwired zones. Install 2
kohm, end-of-line (EOL) resistors on all unused factory programmed onboard
hardwired zones. If you don't want to install EOL resistors, delete any unused
zones from memory.
Zone inputs 1 through 8 are supervised using the included 2-kohm, end-of-line
resistors at the last device on each circuit. All eight zones accept either normally
open (NO) or normally closed (NC) detection devices.
