Power connection (basic)

The NSS display can be powered by either 12 V
or 24 V DC. Displays are protected against reverse
polarity, under voltage and over voltage.
The supplied power cable has a four core cable
used for:
• power into the system (Red and Black wires)
• controlling power state of the display or power
state of other displays and devices (Yellow wire)
• connecting to an external alarm (Blue wire)
Connect red to (+) DC using a 5 amp fuse for NSS12, and a 3 amp fuse for NSS7 and NSS8.
Connect Black to (-) DC. The display can be powered on and off using the power button.

Power Control (yellow wire)

Planning is required how you want to be able to turn on and off the NSS an connected com-
patible devices.
The yellow (Power Control) wire on the NSS power cable can either be an input that will turn
on the display when power is applied, or an output that turns on other devices when the
display is powered on. It can be confi gured at the installation stage to control the power state
of displays and compatible devices. When commissioning the system, displays can be set to
be a Power Control Slave or Power Control Master.

• use the Power button to turn on the display only: Yellow wire not connected
• display to turn on when power is applied to the display: Common red and yellow wires
• use the Power button to turn on the display and other displays and or compatible devices
such as Broadband Radar: Yellow wire connected to a Power Control Bus. (Set one or more
