PRIMARY DISCONNECT
ETHERNET DISPENSER
DISCONNECTS
By connecting to the site’s emergency stop system, Ethernet
Primary Dispenser Disconnects provide low voltage disconnection
for dispensers that use Ethernet network cabling for primary
dispenser communication. Models are available that will
disconnect 1 or 2 Ethernet cables for 8 dispensers or disconnect
one Ethernet cable for 16 dispensers.
HIGHLIGHTS
• Primary disconnect for dispensers using Ethernet
connectivity for data and credit card communication.
• Aids in compliance with NFPA® and NEC® codes.
• Suitable for new and retrofit applications.
• Expandable for the future.
• Compact modular design.
• Lockable cover for lockout/tagout requirements.
• Wall or rack mounted options available.
• Primary disconnect models disconnect the conductors
when the emergency stop system is activated.
• Connect to the emergency stop system by the means of a
Class 2 transformer that is plugged into an outlet
controlled by the emergency stop system.
• Toggle switches, located behind a lockable cover, allow
you to isolate the conductors of a single dispenser for
servicing purposes.
• Expandable to allow disconnecting of additional
secondary communication circuits such as intercom and
media circuits. This is easily done by connecting the
secondary disconnects to the remote expansion port
located on the side of the primary disconnect.
• Individual disconnects for each circuit types allows the
disconnect to be located where the conductors enter the
building. This can eliminate costly additional wiring and
downtime that maybe required to re-route conductors to a
central location such as the electrical room, during a
retrofit or site upgrade.
