An ELC (Emergency Lighting Control) is a small module that converts a standard LED luminaire into an emergency-capable fixture powered by central battery. Sage offers six ELC variants because different fixtures need different power outputs.
What an ELC does
An ELC sits inside (or beside) a standard LED luminaire. In normal operation, the luminaire runs from the building's AC power as usual. When AC power fails, the ELC instantly switches the luminaire to a low-voltage DC feed from a central battery system, keeping the LEDs on at a controlled brightness for the required 90-minute emergency duration.
Why six different SR variants
Different LED fixtures draw different amounts of normal-mode power. An ELC must be sized correctly for the host fixture. Sage offers six SR-series ELCs to cover the practical range:
- SR1 — Compact luminaires (10–70W normal, up to 15W emergency)
- SR2 — Standard luminaires (small to medium)
- SR3 — Medium-power luminaires (30–100W normal, 20W emergency)
- SR6 — Higher-power luminaires (5–70W normal, 24W emergency adjustable)
- SR7 — High-bay luminaires (50–400W+ normal, 60W emergency, dual-channel)
- SR03 — Highest-power applications with 480VAC input option
Factory-installed vs. field-installed
Sage SCB Fixtures (general lighting with optional ELC) ship from the factory with an ELC pre-installed and pre-wired — these arrive ready to connect to a central battery system. Standalone SR-series ELCs are available for retrofitting an existing third-party LED luminaire to operate with central battery emergency power.
