Timed Toggle Protocol
What is “TTP”?
TTP, or Timed Toggle Protocol, is a beautifully simple solution to an otherwise vexing problem: How to provide sophisticated features like dimming and color change with no external control modules, using any standard off-the-shelf switch. Frequently emulated to the point of being almost an industry standard, Lumitec’s innovative TTP control uses brief “off/on” toggles of the light’s power switch to select an intensity level or cycle through output colors.
How does it work?
The light is installed like any 12 or 24VDC light using a positive and negative power wire controlled by any standard on/off switch. Lights with dimming functionality ramp up in intensity over a period of about 4 seconds when initially turned on. A brief "off/on" toggle of the switch during the ramp phase will interrupt the ramp and hold the light at that intensity. To change the output color or output mode of multi-color or multi-output lights with TTP technology, briefly toggle the light OFF then immediately back ON. The light will cycle to the alternate or next output color.
Use the diagram below for the correct operation procedure for TTP.
