Sonesse Ultra 504 RTS (24V DC)

Product Description

The Sonesse Ultra 504 RTS (24V DC) square head motor features a built-in radio receiver that allows for wireless radio control of window shades. Because the motor is radio frequency based you can control the shades from any room wirelessly within a 65’ (1,981 cm) radius of the motor. The 4Nm torque allows for a single Sonesse Ultra to multi-band up to six shades. The acoustic performance of less than 38dB- provides reduced operational noise levels and comes with a 24V power wire. This low-voltage motor requires a transformer and/or power panels and cannot be parallel wired.

ANSI/WCMA A100.1 Compliance

If clutch-operated roller shades are installed in an environment where it's possible that young children will be present, they should comply with ANSI/WCMA A100.1, the Standard for Safety of Window Coverings.

If the shades that you purchase need to comply with this standard, it is your responsibility to inform Draper and opt-in to receive compliant products at time of order.

Compliant window shades will include:

  • Pre-installed spring-loaded chain tension device with bead chain threaded through it
  • Approved permanent warning label attached
  • Approved mechanical fasteners for the tension device included

If the tension device is not installed properly, or becomes unattached from the mounting surface, the shade will be rendered partially inoperable. If installed properly, the tension device will prevent the creation of a hazardous loop and will maintain tension on the bead chain. The tension device and label require tools to be removed.


The testing required by the WCMA for products to comply with safety standard A100.1 includes:

  • UV stability testing - AATCC Test Method 16 for UV Stability
  • Impact testing - ASTM D5420
  • Bead chain durability testing
  • Operation cycle testing - 3,000 cycles per the standard

Draper's spring loaded tension device passed the requirements of these tests.
