Lithonia Lighting QUANTUM ELM2L Manual

FEATURES & SPECIFICATIONS
INTENDED USE — Provides a minimum of 90 minutes illumination for the rated wattage upon loss of
AC power to meet and exceed code required emergency lighting. Ideal for applications requiring attractive
LED unit equipment with quick installation and unparalleled performance for lower mounting heights.
Certain airborne contaminants can diminish the integrity of acrylic and/or polycarbonate.

CONSTRUCTION — The housing is a standard white (black optional) thermoplastic with a compact and
low-profile contemporary design. It is 5VA flame rated, impact-resistant, scratch-resistant and corrosion
proof. The UV-stable resin resists discoloration from natural and man-made light sources. There is a
low-profile, integrated and back-lit test switch with an easily visible multi-color LED status indicator. The
back-plate contains a universal j-box mounting pattern to facilitate ease of installation on a wide variety of
j-boxes and the front housing allows tool-less access for ease of maintenance. US Patents Pending.
ELM2LF: Fixed lamp head arrangement for ease of installation and maximum path of egress aiming
coverage with no aiming required for wall mount applications.
ELM2L: Unique track and swivel arrangement permits full range of direction for lamp head adjustment.
OPTICS — Both the ELM2L and ELM2LF feature two, high performance LEDs with acrylic lens' rated at 1.2
watts each and delivering a total of 220 lumens in a linear pattern (LP220L). The typical life of an LED is 10
years. The LED light sources typically never need to be replaced under normal conditions for normal
off applications.
ELECTRICAL — Orderable in multiple voltages (see ordering tree for specific voltages).
Current-limiting charger maximizes battery life and minimizes energy consumption to meet California
Energy Commission Title 20 requirements for small battery charger systems and provides low
operating costs.
Short-circuit protection — current-limiting charger circuitry protects printed circuit board from shorts.
Regulated charge voltage maintains constant-charge voltage over a wide range of line voltages.
Prevents over/undercharging that shortens battery life and reduces capacity. Filtered charger input
minimizes charge voltage ripple and extends battery life.
BATTERY: Sealed, maintenance-free nickel-cadmium or Lithium Iron Phosphate.
Lithium Iron Phosphate battery powers both on board LEDs and up to 2.4W additional LED remote lamp
heads simultaneously or offers extended run-time up to 3 hours.
SELF-DIAGNOSTICS and REMOTE TEST (SDRT option):
Automatic 24-hour recharge after a 90-minute discharge.
Advanced electrical design provides constant light output throughout the entire discharge period.
Brownout protection is automatically switched to emergency mode when supply voltage drops below
approximately 80 percent nominal of 120, 220, 277 or 347. Other input voltages may vary.
AC/LVD reset allows battery connection before AC power is applied and prevents battery damage from
deep discharge.
Self-Diagnostics: Continuously monitors AC functionality. Test switch and remote tester (ELA LRT accessory)
provides manual activation of 30-second diagnostic testing for on-demand visual inspection. Standard
derangement monitoring will indicate disconnected battery, charger failure and displays green flashing
indicator light while in emergency mode. Single multi-chromatic LED indicator to display two-state
charging, test activation and three-state self-diagnostics.
Self-diagnostic testing: Five minutes every 30 days and 90 minutes annually. Diagnostic evaluation of
lamps, AC to DC transfer, battery charging and condition of microprocessor. Automatic test is easily post-
poned for eight hours by activating manual test switch or use of remote tester (ELA LRT accessory).
INSTALLATION — Wall mount and ceiling mount standard for ELM2L. Wall mount only for ELM2LF.
Blind-mate connector ensures easy installation and safe maintenance. 7/8" entrance provision at top of
unit for standard 1/2" conduit entry. Tool-less removal of front cover from back-plate for ease of installation
and maintenance.
LISTINGS — UL damp location listed standard and wet location listed when used with the WPVS
accessory, all at 50-104°F (10-40°C). Meets or exceeds all applicable requirements for UL 924, NFPA 101
(current Life Safety Code), NFPA 70 (NEC), NOM (Norma Oficial Mexicana), California Energy Commission
Title 20 section 1605.3 (W)(4), FCC and OSHA. List and labeled to comply with Canadian Standards
C22.2 No. 141-10.
WARRANTY — 5-year limited warranty. Complete warranty terms located at:
