Lutron Emergency Lighting Interface - 3-Phase Power Loss Detector - UL 924 | LUT-ELI-3PH

Lutron LUT-ELI-3PH Emergency Lighting Interface (3-Phase Detector)

The Lutron LUT-ELI-3PH is a specialized safety interface designed to monitor three-phase normal power and coordinate with Lutron lighting control systems during power emergencies. This unit is essential for commercial buildings, ensuring that in the event of a power loss on any phase, the system automatically bypasses normal controls and forces emergency lighting to a pre-defined level (typically 100% brightness).

Fully UL 924 Listed for Emergency Lighting Equipment, the LUT-ELI-3PH provides a reliable dry-contact closure output that connects directly to the emergency input of GRAFIK Eye QS, HomeWorks, Quantum, and Athena systems. Its wide voltage sensing range (100V to 347V) makes it compatible with nearly all global electrical standards.

Key Features

• UL 924 Listed: Meets strict life-safety requirements for emergency lighting equipment.
• 3-Phase Monitoring: Senses the loss of any individual phase or the entire power source.
• Universal Voltage Sensing: Monitors voltages from 100V up to 347V AC per phase (50/60 Hz).
• System Integration: Provides a dry contact closure output (Normally Open or Normally Closed) to trigger emergency mode on Lutron control links.
• Local Testing: Includes a built-in test button and LED indicator to verify proper operation during routine safety inspections.
• Durable Enclosure: Housed in a compact, NEMA 1 industrial enclosure for surface-mount installation.
