Get to know this product.

An advanced single-channel dimmer module controlled by DALI®. Supports dimmable 3-wire fluorescent ballast lighting loads. UL® 924 listed for emergency lighting control applications.

The Crestron Green Light® GL-EXP Series delivers a family of professional lighting control modules for Cresnet® or DALI® based lighting systems. Designed for easy installation on a wall or above a suspended ceiling, these modules offer a perfect solution for adding extra lighting zones to any system without requiring an additional lighting cabinet.

The GL-EXP-DIMFDB-DALI is a single-channel dimmer expansion module designed to control 3-wire electronic fluorescent dimming ballasts. Utilizing proprietary zero-cross filter technology, the GL-EXP-DIMFDB-DALI compensates for line voltage and frequency fluctuations, providing superior immunity to power line noise and a dramatic reduction in lamp flicker.

DALI® Communications

  • The GL-EXP-DIMFDB-DALI communicates using the DALI (Digital Addressable Lighting Interface) standard, which enables interoperability with other DALI compliant lighting control products from Crestron and other manufacturers. Interfacing a network of DALI dimmers and other devices with a Crestron lighting control system is facilitated using the DIN-DALI-2 (sold separately).

Emergency Lighting Control

  • The GL-EXP-DIMFDB-DALI is UL® 924 listed for use in controlling an emergency lighting load. In the event of a power failure indicated by a loss of DALI network communication (system failure), the GL-EXP-DIMFDB-DALI turns on the lighting load if it is off (assuming line power is supplied by a backup power source). The system failure dimming level can be preset to any value when commissioning the lighting system, so even if the load is already on prior to a power failure, it will change to the preset level when a system failure is detected.

Plenum Rated NEMA Enclosure

  • The GL-EXP-DIMFDB-DALI is designed to be mounted to a vertical surface and is UL 2043 compliant to allow for installation in an environmental air-handling space above a suspended ceiling. Conduit knockouts are provided on the bottom and lower sides of the unit. All connections are made via screw terminals behind the front cover.
