Buying Guide
- Type and visibility: Choose signs with clear “EXIT” lettering, appropriate arrow directions, and dual- or single-sided designs depending on sightlines and hall width.
- Power and battery backup: Consider models with long-duration emergency lighting (90+ minutes) and reliable battery chemistry (NiCd or NiMH).
- UL/NFPA compliance: Ensure the product is UL 924 listed and meets NFPA 101/70 requirements for life safety and electrical installations.
- Mounting flexibility: Look for wall, ceiling, or side-mount options, plus features like canopy mounting and adjustable light bars for optimal illumination.
- Durability and location: For outdoor or damp areas, prioritize weatherproof and corrosion-resistant housings (e.g., aluminum or impact-resistant plastics).
- Color options and visibility: Some models offer red or green lettering; consider your building’s color-coding standards for wayfinding consistency.
- Maintenance and testing: Pick signs with easy test mechanisms (push-to-test) and simple component access for periodic inspections.
- Installation context: In crowded corridors or warehouses, dual-face or double-sided signs may improve visibility; in narrow paths, slim-profile signs help reduce protrusions.
- Budget and reliability: Prioritize reputable brands with UL certification and long-term warranty coverage to minimize maintenance costs.
- Future-proofing: If codes or layouts change, choose modular or adaptable signs that allow faceplate swaps or reorientation without full replacement.
