How to Configure Zone 8 for an AB-12 UL Bell
Point 8 on a G/GV2/GV3 series panel is shorted even though there is a 1K end-of-line resistor accross the circuit.
Be sure that jumper S3 (next to terminal 22) is latched down securely. When this jumper is open, it disables the ground fault detection on point 8, as well as changes the EOL value on this point to 220K ohms for use with a AB-12 UL Bell Box. The panel will see the 1K ohm resistor as a shorted condition.
