Terms

In trying to understand motorized shades, it is important to know certain terminology. These terms used by Draper, electricians, and others

when discussing motorized cover how power brought to the shades, wire size used, control types used, and more.

High Voltage or Line Voltage—These terms refer to 110 or greater voltage. In the US and Canadian markets, most high voltage shades jobs

are supplying 110 to 120 VAC to the motors. This type of voltage will most likely be in conduit.

Low Voltage—For Draper shades, this is referring to 24 VDC. Low voltage power comes from a transformer receiving high voltage.

Transformer—For Draper shades, this is an item that changes high voltage to low voltage.

Conduit—This is the metal piping that is used to protect wires in the ceiling or walls.

Gauge—This refers to the diameter of the wires. For Draper high voltage shades, the gauge of wire going from the motor to the controls is typi-

cally US 18 gauge. Lower numbers are large diameters.

Pigtail or Motor Lead—This refers to the wires coming off of the motor. The standard length for these is 6’, but they can be ordered up to 24’.

Amps or amperage—This is a measurement of power on an electrical circuit. You may be asked the amp draw of a motor so the electrician

does not put too many motors on an electrical circuit.

Home run—This refers to a straight line of wires being supplied from a singular motor to a singular controller or singular port on a controller.

Parallel Wiring—This refers to 2 or more motors being wired together to a controller or a port on a controller.

Dry Contact—These are the closures on a controller. There are three ports that make up the closure; up, common, and down. The common

port is sending out power. When the common port connects with either the up or down port then the shade will react in that direction. This type

of closure allows for low voltage systems to operate shades.

RS 232, RS 485, RS 422—These are computer languages that can be used to operate shades.

Data Cable and CAT 5—These are the low voltage wire used to carry power to low voltage shades or communication signals between low volt-

age devices.
