Compliance & Safety
Use with Lighting Loads Only | Not for lamps with integral dimmers or touch controls; set 3-way lamps to full-on. |
Low-Voltage Guidance | Use magnetic (core/coil) LV transformers only; do not operate with lamps removed; use thermal protection or fused primaries where possible. |
Polarized Plug | Plug fits polarized outlets one way for safe operation. |
Application Examples
- Scene-controlled table and floor lamps in living rooms, bedrooms, and home offices.
- Retrofit dimming where hard-wiring isn’t practical.
- Task and accent lighting integrated into RadioRA 2 scenes.
Installation Tips
- Plug the lamp into the dimmer, then plug the dimmer into a standard polarized outlet.
- Place the device within approximately 30 ft of a RadioRA 2 repeater for reliable RF communication.
- For MLV loads, use only magnetic transformers and replace burned-out lamps promptly.
- Do not use with lamps that have integral dimmers, touch controls, or dioded bulbs.
- For lamps with 3-way switches, set the switch to full-on.
Frequently Asked Questions
Q: What loads can this dim?
A: It dims incandescent/halogen and magnetic low-voltage loads within the ratings. CFL/fluorescent/ELV can be switched on/off only.
Q: Does it work with RadioRA 2 scenes?
A: Yes. It communicates via RF to the RadioRA 2 system and should be within about 30 ft of a repeater.
Q: What happens after a power outage?
A: The dimmer has power-failure memory and returns to the previous state when power is restored.
Q: Can I use it with electronic low-voltage transformers?
A: No. Use only magnetic (core & coil) low-voltage transformers.
Q: Does it have a nightlight?
A: Yes. Status LEDs indicate the level and glow softly when the lamp is off.
Q: What is the maximum wattage?
A: Up to 300W for incandescent/halogen; up to 200W/300VA for magnetic low voltage.
Q: Is it indoor-only?
A: Yes. Operate between 32°F and 104°F, 0–90% RH, non-condensing.
Q: Are other colors available?
A: Yes. Snow (SW) and Midnight (MN) finishes are available.
