Dimmer Switch - Leviton DSM10 Universal Dimmer

Is a neutral wire required with the Leviton Universal Dimmers?

No, the Universal Dimmers are two wire devices that can replace any standard electrical switch.

What are the LED load ratings for the Decora Rocker Slide Dimmer?

The DSM10 Decora Dimmer has a 450W (3.75A) load rating.

How do I turn the Decora Rocker Slide dimmer locator light ON or OFF

A LED on/off selector is located under the rocker switch. Simply remove the color change kit face and turn the switch to the desired position.

Why are my lights still on, or glowing, when the dimmer is in the OFF position?

When the locator light is in the ON position, a very small amount of current is passed through the LED bulb. Very sensitive LED bulbs may appear to glow from this current. To fix, turn the locator light to the OFF position.

The packaging indicates that the Universal Dimmers are suitable for single pole and 3-way applications, what does that mean?

Single pole means controlling one or more lighting fixtures from one location. 3-way is the ability to control one or more lighting fixtures from two separate switch locations. An example of a 3- way is the ability to control the same fixture from a switch at the top of a staircase and from another switch at the bottom of the staircase. The Decora Rocker Slide Universal Dimmer can only be dimmed from a single location and turned ON and OFF from the second location (to the current dim level).

Are there any adjustments I will need to make to the Universal Dimmer based on the bulb I choose?

The universal dimmer is preset to the LED/Incandescent mode. Under most conditions, the dimmer can be used with all compatible bulb types in this mode. If you experience flicker in the low end range of dimming, the low end trim adjustment can be used to improve performance. Some dimmable CFL bulbs may require an additional “kick start*”, or automatic adjustment, to turn on. In this case, it is necessary to adjust the dimmer to CFL mode.

Why is there no light from the LED bulbs when the dimmer is ON at the lowest dim setting?

The universal dimmers have been designed to function with a variety of LED bulbs. Some LED bulbs are more sensitive than others, and need a higher voltage to “turn on”. In order to fix this, raise the low-end trim adjustment until the LED bulb turns ON.

My lights sometimes turn off before the dimmer slide is at its lowest level. Why does that happen and can I fix that?

Leviton Universal Dimmers feature an easy to use selector switch for choosing bulb applications. It is pre-configured to the LED/Incandescent mode which is optimized for a wide range of LED applications. In CFL mode the dimmer provides a “kick start*” feature for harder to start bulbs. In CFL mode, the dimmer’s “kick start” feature maximizes the useable dimming range for many bulbs by allowing the user to turn on the light at the lowest possible position. The selector switch has an optional programming mode. The programming mode option is used to change the factory settings for minimum light level. For example, the dimmer settings can be changed to eliminate any noticeable flicker or users can re-calibrate the pre-set to ensure the bulb starts at the lowest light level.
