Product overviewCentralized-supply, centralized-control in-ground fire emergency luminaire designed to indicate ground evacuation routes. Suitable for high-rise buildings, shopping malls, entertainment venues, banks, hospitals, metro and railway stations, airports and other crowded public spaces. In fire conditions the luminaire is managed by the fire emergency lighting and evacuation indication system to provide clear, rapid route guidance.
Key features- Two-bus non-polar control and power supply to reduce installation cost and simplify wiring.
- Green ultra-bright LED light source for low consumption, long service life and easy replacement.
- Constant-current driver for stable luminance.
- Robust construction with resistance to high temperature and corrosion for varied environments.
- Human-centred ground indication for intuitive evacuation guidance.

Applications & installationDesigned as an in-ground (buried/recessed) fixture for built environments. Integrates with centralized battery and two-bus fire emergency systems. Install in escape routes, stair approaches and thresholds where ground-level indication improves visibility and orientation. Ensure compatibility with the site's centralized control wiring and observe IP67 sealing during installation.
Standards & maintenance- Complies with GB17945-2010 (Chinese CCCF) standard.
- Regular functional checks recommended as part of the building's emergency lighting maintenance plan; replace LEDs and driver components according to operating hours and site procedures.
