Dispenser Disconnect

All-In-One

All-In-One Dispenser Disconnects offer a flexible approach to disconnecting low voltage circuits including, data, credit cards, intercom/communication, and video/media circuit conductors connected to dispensers. Primary and secondary disconnects for both twisted pair and Ethernet circuits are combined into one space-saving, pre-configured enclosure.

ALL-IN-ONE DISCONNECTS

Combines the capabilities of both Primary and Secondary Disconnects into one solution with the ability to disconnect all low voltage dispenser wiring conductors including twisted pair and Ethernet.


Emergency Stop

In the event of an emergency stop, the All-In-One Disconnect will disconnect the dispenser data, credit card data, intercom, and media communication circuits.

Safe Maintenance

Toggle switches, located behind a lockable cover, allow maintenance personnel to isolate the conductors of a single dispenser for servicing purposes.

NFPA® and NEC® Code Compliance

Dispenser Disconnects provide compliance with NFPA® and NEC® Code requiring emergency disconnect and maintenance disconnects at all motor fuel dispensing facilities.

ALL-IN-ONE DISPENSER DISCONNECTS

Primary and Secondary disconnect for dispenser data, credit card data, intercom, and media for dispensers equipped with both Twister Pari and Ethernet circuits for data communication.

Simultaneous Disconnect

Low voltage dispenser wiring can be disconnected simultaneously when the dispenser power is interrupted by the dispenser breaker or other disconnect.

Expandable

Easily expandable to disconnect additional low voltage dispenser circuits by connecting a secondary disconnect using the remote expansion connector located on the side.

Remote Installation

Additional secondary disconnects can be installed remotely near the location of the conductor entry into the building, eliminating costly wiring and downtime that may be required to re-route conductors to a central location such as the electrical room, during a retrofit or site upgrade.

Ordering Guide

Complete part numbers have a specific order and are created using the following guidelines:

DDS-A XD Y E P

DDS-A = All-In-One Dispenser Disconnect

XD = # of Dispensers
4, 6, 8, 10, 12, 16 = 4, 6, 8, 10, 12, 16 Dispensers

Y = # of Intercom Conductors
4 = 4 Intercom Conductors per Dispenser
8 = 8 Intercom Conductors per Dispenser

E = Ethernet Circuits
Blank = No Ethernet Circuits
E = 1 Ethernet Circuit per Dispenser

P = Surge Protection
Blank = No Surge Protection
P = Surge Protection
W = Surge Protection for Wayne® Dispensers
