Lithonia Lighting LED Exit Sign, Red, LQM SW3R120/277ELN
Ideal for applications requiring attractive, quick-installation LED exit signs and low energy consumption.
Engineering-grade thermoplastic housing is impact-resistant, scratch-resistant, and corrosion-proof. UL94V-0 flame rating. UV-stable resin resists discoloration from natural and man-made light sources.
Rugged unibody housing snaps together with no additional mechanical fasteners. Faceplate and back cover are interchangeable on housing. Positive snap-fit tabs hold faceplate securely, yet easily removable for lamp compartment access. Universal directional Chevron inserts are easily removed and reinserted. Uniform illumination without shadows or hot spots. Reinforced, impact-resistant color panels. Letters 6” high with 3/4” stroke, with 100 ft. viewing distance rating.LEDs mounted on printed circuit boards. Expected LED life of up to 10 years. Low energy consumption – less than one watt. LED lamp operates in normal (AC input) and emergency (DC input) modes.
Low-voltage disconnect prevents excessively deep discharge that can permanently damage battery. Conveniently located test switch and LED provide visual and manual means of monitoring system.
Constant-current series charger minimizes energy consumption and provides low operating costs. Printed circuit boards are 100% quality tested during manufacturing. Current-limiting charger circuitry protects printed circuit boards from shorts. AC/LV reset (line latch) allows battery connection before AC power is applied and aids in preventing battery damage from deep discharge.Crystal oscillator timing system with watchdog protection for precision accuracy.
Brownout protection is automatically switched to emergency mode when supply voltage drops below 80% of nominal.
Battery: Sealed, maintenance-free nickel-cadmium battery delivers 90-minutes capacity to emergency lamps. Two-state constant-current charge maximizes battery life and automatically recharges after battery discharge.
Diagnostics: Single-point microcomputer control for all electronic features.
Single multi-chromatic LED indicator to display two-state charging, test activation and three-state diagnostic status.
Test switch provides manual activation of 30-second diagnostic testing for on-demand visual inspection. Self-diagnostic testing for five minutes every 30 days and 30 minutes every six months.
Diagnostic evaluation of LED light source, AC to DC transfer, charging and battery condition. Continuously monitors AC functionality.
INSTALLATION — Universal (top-, end-, or back-) mounting. Easily removed
