Wiring the DS7412
4. Re-apply power and set the panel time and date using a master PIN.
Jumpers
There are three jumpers on the Detection Systems circuit board that must be configured.
Diagnostic LEDs
Jumper P2 controls the diagnostic LEDs, which can be used as a troubleshooting aid. To enable the LEDs,
place P2 on both pins.
The DS7412 draws more current in this mode so P2 should not be in place under normal circumstances.
RS-232 Cable Ground
Some printers may cause a ground fault condition on the control panel. If this occurs, remove P3. This will
disconnect the printer cable ground from the cabinet ground.
Some desktop computers can cause a ground fault even if P3 is removed. If connecting the DS7412 to a
desktop PC and a ground fault occurs, use the connection only temporarily and disconnect for normal
control operation.
