Answer:
The PEL LED LML combines maintained EXIT signage with non-maintained 2x3W twin LED beam lamps in a single 22-gauge MS C.R.C.A enclosure. While the illuminated EXIT sign stays continuously active, the twin emergency lamps automatically strike via an internal switching relay the moment AC mains power fails.
The Prolite PEL LED LML integrates two distinct functional emergency lighting modes into one self-contained unit:
- Combined Operation Mode: The EXIT sign operates in Maintained mode, ensuring continuous visual route guidance, while the twin 2x3W beam lamps operate in Non-Maintained mode, engaging immediately upon primary AC utility failure.
- Relay-Driven Switching: Transfer from charging to emergency backup illumination is handled automatically by an integrated switching relay with zero manual intervention required.
- Heavy-Duty Fabricated Construction: Built from robust 22-gauge MS C.R.C.A (Cold Rolled Cold Annealed) sheet metal coated with white epoxy polyester powder, complemented by clear molded ABS/polycarbonate optical diffusers.
- Testing & Status Diagnostics: Features an external polyamide push button switch for circuit testing and a dedicated red LED indicator confirming active mains supply and operational readiness.
