Low Intensity Type B — Dual Voltage with Fault Monitoring
ICAO-compliant twin-dome aviation light with a separate alarm panel. Accepts both 230V AC and 48V DC — continues operating from battery bank during mains failure. NMS alarm on power fail or light fail.
The Problem It Solves
Single-Supply Lights Fail When Mains Fails
Many sites use 230V AC aviation lights. When mains power fails and there is a generator startup delay (or generator failure), the aviation light goes dark — making the tower non-compliant and creating a safety hazard. Additionally, if the only installed light fails, it may go unnoticed for days. The Dual Voltage with Fault Monitoring model solves both problems simultaneously.
Takes both 230V AC and 48V DC simultaneously. AC mains preferred. On mains failure, 48V DC battery bank takes over automatically — no gap in compliance.
Alarm panel monitors current consumption. If below ~65% of rated value, 'light fail' NMS alarm is raised via potential-free NO/NC contacts.
If both AC mains and DC input fail, 'power fail' NMS potential-free contacts are activated for immediate centralised alerting.
Two domes on a single unit, both ON simultaneously (<6W). Special J-plate/J-clamp mounting — no welding or drilling required.
