Install and Configure Slot/Door-Mount Controllers
Step Action
4 Configure the 1-Wire serial bus reference:
The ES771 modules must be referenced to the most negative potential of the DC bus. This
reference is achieved by the proper setting of Jumper 11 (board reference J35) that is located
next to the alarm relay configuration jumpers. The jumper is set in the factory for Positive
Grounded systems (-48V) unless the controller is shipped with an assembled system that has a
pre-determined primary output bus. An insulated tool must be used to set the jumpers.
For systems with Positive Grounded batteries (-48V/-24V), move 1-Wire Reference jumper 11
(J35) to the Positive Grounded position. For systems with Negative Grounded batteries (+24V),
move jumper 11 (J35) to the Negative Grounded position as shown: Again, the appearance of
the jumpers may seem different when the controller is a slot-controller or a door-mount
controller because of the orientation of the circuit board.
Make sure the jumper cover is returned in slot-mount controllers.
Securing the Slot-Mounted Controller
For NE843C/NE843E based systems go to next section on connecting the controller. The
following is for the NE843A/CP843A/EP843D slot-controllers.
5
Place the NE843A/CP843A slot-mounted
controllers into a left-most power. The
EP843D goes into the right-most power
slot.
Open the latch on right-hand side of the
front panel by pushing down on the edge
of the “blue” latch tab.
