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.

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.
