The GLS-PLS-120/277 is a 3-Phase Power Loss Sensor designed for use with Crestron Green Light™ systems to activate Override mode during a power failure. In response to a signal from the GLS-PLS-120/277, the lighting system program can be temporarily overridden while designated emergency lighting circuits are changed to their override preset levels and unnecessary lighting and other devices are shut down to minimize the demand on emergency power equipment.
- Senses loss of power on each leg of a 3-phase feed
- Used to satisfy UL 924 (Emergency Power Equipment) requirements
- Works with 120 or 277 Volt feeds
