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-SW-CN is a single-channel switch expansion module designed to control a wide range of non-dimmable lighting loads including LED, incandescent, fluorescent, magnetic low-voltage, electronic low-voltage, neon/cold cathode, and high-intensity discharge. It can also be used to switch motor loads.

Cresnet® Communications

The GL-EXP-SW-CN interfaces with a Crestron® control system via Cresnet. Cresnet is a simple 4-wire network bus that provides the communications backbone for a system of Crestron lighting dimmers, switches, keypads, shades, thermostats, and other devices.

Emergency Lighting Control

The GL-EXP-SW-CN is UL® 924 listed for use in controlling an emergency lighting load. In the event of a power failure, a contact closure from a power loss sensor (Crestron GLS-PLS-120/277) activates the override mode in the GL-EXP-SW-CN to turn on the lighting load if it is off (assuming line power is supplied by a backup power source).

Plenum Rated NEMA Enclosure

The GL-EXP-SW-CN 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.
