Buying Guide: Key Purchase Considerations
When selecting a side-mount exit sign, consider these factors to ensure effective wayfinding and long-term reliability:
- Mounting flexibility: Look for side, top, and wall mounting options, plus universal canopies to fit existing junction boxes.
- Power and backup: Check voltage compatibility (120V/277V or wider ranges) and the type of backup battery (Ni-Cd or Ni-MH) and its expected runtime (typically 90-120 minutes).
- Durability and environment: Damp-rated vs. wet-location ratings determine suitability for indoor hallways or outdoor areas, garages, and entrances exposed to moisture.
- Lighting technology: LED edge-lit or panel designs offer different aesthetic looks and efficiency; ensure adequate brightness and clear visibility from a distance.
- Visibility and chevrons: Directional arrows and removable chevrons enable flexible wayfinding; verify field-installable arrows are included if needed.
- Election of color: Red vs. green color options can meet local code or preference; some models toggle colors on a single unit.
- Maintenance and test features: Push-to-test or illumination indicators simplify routine checks and ensure compliance.
- Compliance: Ensure UL 924 listing and NFPA/NEC compatibility for your facility type and occupancy.
Comparative Considerations
To decide between the options above, map your priorities to these criteria:
- Indoor hallways with dry or damp conditions: prioritize damp-rated, energy-efficient LED signs with easy top/side/wall mounting, such as Lithonia EXRG M6 or LEONLITE variants.
- Exits exposed to moisture or outdoors: choose wet-location capable models with robust IP ratings and weather-resistant housings, such as SITISFI outdoor options.
- Sign direction needs: if your space requires two-sided visibility or field-adjustable arrows, select models with double-face designs and removable chevrons.
- Budget and installation speed: pick signs with universal mounting kits and plug-and-play accessories to minimize downtime during retrofit projects.
All five selections provide reliable emergency illumination with battery backup and meet common life-safety requirements. Consider your building’s layout, occupancy type, and local code mandates when finalizing a purchase.
