    Nexus® Option

    • Units equipped with Nexus® self-testing monitoring system circuitry shall self test, in accordance with NFPA101, Life Safety Code minimum 30 seconds every 30 days, 30 minutes every six months and 90 minutes annually as well as keep a history of all testing logs, plus feature a real-time diagnoses, as well as, be able to locate exact fixture location while notifying service personnel to the status of the fixture via email notification. Nexus® system interface with an improved minimum load lost detection of 10%

    Load Shedding

    • During a power outage the emergency fixture is dimmed to 25% or 45% brightness output. Reducing wattage draw from the fixture will allow for more fixture to be connected to the Mini Inverter.
    • Maximum 20 Emergency fixtures can be daisy chained per EMIU 250
    • In standby mode, the maximum normally-on load that can be connected to EMIU-250-LD is 960 watts

    Sealed maintenance-free battery

    • 12V oversized valve regulated lead-calcium (VRLA) battery
    • Provides 90 minutes of emergency operation
