FEATURES
The IOTA IIS-125-CG is a UL Listed stand-alone modified sine wave output inverter
designed to provide power to designated emergency lighting fixtures. In a power loss
situation, the IOTA IIS-125-CG will supply 125W of power from the onboard battery supply.
The IOTA IIS-125-CG works in conjunction with incandescent, LED, and fluorescent
lamp and fixture types and will automatically run switched, normally-on, or normallyoff designated emergency fixtures. The IIS-125-CG is ideal for applications requiring
an emergency source for lighting arrangements that utilize multiple lamp and fixture
types. The IIS-125-CG is designed for installation in the ceiling grid and comes with a
three-year warranty and seven-year pro-rata battery warranty. The IIS-125-CG is not
for use in air supply/air return ceilings.

High-efficiency modified sine wave inverter
Variable-rate, temperature-compensated charger
12V oversized Valve Regulated Lead Acid (VRLA) battery
IIS-125-CG SAMPLE SPECIFICATION
Emergency lighting shall be provided by inverter unit equipment designed to
operate designated incandescent, fluorescent and LED fixtures on emergency
power at their full nominal lumen rating during the full 90-minute emergency
discharge cycle. System output will be rated at 125 watts for 90 minutes and
provide fused output connections to the load. The system’s voltage rating shall
be field selectable 120 or 277 VAC input/output.
The inverter unit shall allow for connected emergency fixture(s) to be normally
on, normally off, switched or dimmed without affecting lamp operation during a
power failure. Upon utility power loss, the inverter unit shall deliver 100% of its
rated output to the designated emergency fixtures regardless of the local switch
or dimmer position, and will provide power to the emergency fixtures at distances
of up to 1000 feet.
The housing shall be designed for ceiling grid installation requirements excluding
air supply/air return ceiling applications, and shall be manufactured using
18-gauge steel with a white hammer semi-gloss scratch-resistant baked-on
powder coat paint finish.
CONSTRUCTION
18-gauge steel housing
The unit’s electronics shall include a self-contained inverter section with a fully
automatic, thermal-compensating variable-rate battery charger, AC lockout
feature, low battery voltage disconnect, DC overload, short circuit and brownout
protection as standard. The unit shall utilize a sealed lead calcium battery with a
10-year design life. The inverter system shall be UL 924 Listed and labeled. The
unit shall be covered under a 3-year warranty on the electronics and battery and a
7-year pro-rata warranty on the battery. It shall meet or exceed the requirements
of UL 924, NFPA 101 Life Safety Code, NFPA 70 National Electrical Code, OSHA
and State and Local codes.
The inverter unit shall be IOTA Engineering model IIS-125-CG.
TYPICAL WIRING
FLYING LEADS
The additional input leads of the IIS inverter allow for use of switched fixtures
on the emergency circuit. When a loss
of AC power occurs, the fixtures on the
emergency circuit will be powered by
the IIS Inverter supply, regardless of
switch position.
