The ISD420 from IOTA 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, charge, lamp, or inverter by means of a flashing red indicator. The dual color LED indicator is lit red when charging and lit green when ready. The unit contains a battery, charger, and inverter circuit in a single can. The ISD420 can be used with 13W to 57W 4-pin compact fluorescent lamps, providing an initial output of up to 1100 lumens for one or two lamps, and features lamp selector leads for optimizing the light output for designated lamp types. The ISD420 utilizes AC output to ensure compatibility with new lamp technologies. The ISD420 is suitable for use in damp locations.
