The tragic events of 9/11 revealed a complete shortfall in emergency lighting in many of NYC’s buildings and infrastructure.
Pressure from a riders’ advocacy group called the “Straphangers” spurred NYC to develop a specification for an advanced system of efficient LED lighting with long battery life and remote monitoring of battery readiness.
NYC Transit had interest in:
4 hour LED emergency lights (industry standard is 1.5 hours)
Establish Communication between emergency ballast and control panel
Ability to dim lights during day
Testing & Reporting
LEDdynamics control system provides DALI standard compliant communication between Emergency Ballast and Control Panel.
Dims in response to natural daylight
Self Tests per NYC requirements
30 second test every 30 days
30 minute test every 6 months
Reports any failure in battery or light engine to unified control panel
The control system look 5-months to engineer, design, test and install.
