ISD420 Emergency Ballast

Self Diagnostic Emergency Ballast for 4-Pin Compact LED Retrofit (TLED) and Fluorescent Luminaires

By IOTA

  • Overview
  • Specifications
The ISD420 from IOTA Engineering is a UL Listed self-diagnostic fluorescent emergency ballast that allows the same fixture to be used for both normal and emergency operation. In the event of a power failure, the ISD420 switches to the emergency mode and operates one of the existing lamps for 90 minutes. The ISD420 will self-test for thirty seconds monthly and for ninety minutes annually and will diagnose potential problems within the light fixture. If problems are encountered, the unit will specify failure of the battery, charging circuit, lamp, or inverter by means of a flashing red indicator.
