The Lithonia Lighting EDGR and EDGRNY series are recessed edge-lit LED exit signs designed for both standard and New York-approved applications. Installation requires adherence to specific safety precautions and building codes. These instructions cover surface mount and recessed installations, emphasizing electrical safety and proper wiring procedures. The documentation details mounting configurations, wiring diagrams, and operational considerations for both emergency and non-emergency circuits, as well as emergency lighting (EL) operation utilizing battery backups.
Safety Precautions
Prior to installation or servicing, several critical safety measures must be observed. The documentation repeatedly emphasizes the importance of disconnecting power. Users must turn off electricity at the fuse or circuit breaker before wiring to the power supply. For emergency lighting operation, both AC power must be disconnected and the battery unplugged before any servicing is performed.
The documentation also highlights the following safety considerations:
- Consult local building codes for approved wiring and installation practices.
- Do not mount the fixture near gas or electric heaters.
- Do not install a damaged fixture.
- All service should be performed by qualified personnel.
- Equipment should be mounted in locations inaccessible to unauthorized personnel to prevent tampering.
- Avoid using abrasive materials or solvents, as these can damage the fixture and potentially cause injury.
- Wear gloves during handling, installation, and maintenance to protect against sharp edges.
- Keep combustible materials away from hot parts of the fixture.
- Observe all warnings and recommendations provided by the lamp manufacturer.
Installation Procedures
The installation process varies depending on the chosen mounting configuration: end mount, top mount, or back mount. The initial step involves securing the canopy bracket to either the ceiling or wall. Following this, the housing cover is opened to allow access for wiring and mounting.
For surface mount installations, the housing and canopy are secured using screws, with the specific mounting configuration determining the appropriate holes to plug using the provided color-matched plugs. AC input leads are then fed through the center hole in the housing and canopy, and connected to the corresponding AC power supply leads, referencing the wiring diagrams provided in the documentation. The canopy is then secured to the bracket using 1½” long #8-32 screws.
For recessed installations, the documentation references installation instructions specific to the EDGRNY model, but does not provide details within the provided source material.
Wiring and Electrical Connections
Proper wiring is crucial for safe and reliable operation. The documentation stresses the importance of secure wire terminations and ensuring that leads are properly tucked into the appropriate wire channels. Unused wires must be capped with enclosed wire nuts or another approved method.
When utilizing the emergency lighting (EL) function, the battery terminal wire is connected to a two-pin male connector. However, the documentation explicitly states that the battery should only be connected after continuous AC power has been established to the unit.
Operational Considerations
The EDGR and EDGRNY series are designed for use in damp locations, with a listed operating temperature range of 0°C to 50°C. The fixtures are suitable for emergency, non-emergency, and X2 dual-circuit operations. The use of accessory equipment not recommended by the manufacturer will void the product listing and warranty and may create an unsafe condition.
The documentation also provides instructions for applying Chevron directional indicators, if required, and removing application templates after completion.
Product Specifications and Limitations
The provided documentation does not contain a comprehensive list of product specifications. However, it does state that the fixtures are UL damp location listed. The documentation also cautions against using the equipment for any purpose other than its intended use as an exit sign.
Warranty and Compliance
The use of non-recommended accessory equipment voids the product listing and warranty. All installations must comply with applicable installation codes and ordinances. The documentation emphasizes that qualified personnel should perform all service work. Material Safety Data Sheets (MSDS) are available for the brushed aluminum and white paint colors used on the EDG-EDGR, EDGNY-EDGRNY, and EDGC models.
