IOTA ILB-SL-CP10-HE Constant Power LED Emergency Driver Specification
Supply and install IOTA ILB-SL-CP10-HE Constant Power emergency LED driver system as indicated on the plans. The emergency driver
shall be designed for internal mounting to the luminaire including a self-contained, high-temperature, sealed, maintenance-free
nickel cadmium battery rated for a 10-year service life. The unit shall be provided complete with an illuminated push to test switch.
The emergency driver system shall be UL class 2 certified in accordance with UL 1310 and shall be UL listed for use in damp locations
and in enclosed and gasketed fixtures with a temperature range of 0° to 55° C.
The AC input shall be a two-wire, universal voltage capable 120 thru 277 VAC, 50/60 Hz and be UL Listed to Category Control Number (CCN)
FTBR, Emergency Lighting and Power Equipment, and FTBV, Emergency Light-Emitting-Diode Drivers for field installation. Maximum input
power of the emergency driver shall be 3.7 watts. The unit shall monitor and adjust the input power consumption for compliance with CEC
efficiency standards for small battery chargers.
The unit charger shall consist of a two-stage charging system which samples the battery in relation to its temperature, state of charge
and input voltage fluctuations. The charger shall be current limited, temperature compensated, short-circuit protected with reverse
polarity protection. A low voltage battery disconnect (LVD) circuit shall be provided and will disconnect the load and circuitry from the
battery when it reaches approximately 80 to 85% of its nominal terminal voltage, preventing a non-recoverable, deep-discharge condition as
well as equipment initialization failure when utility power is restored. The unit shall achieve a full recharge in 24-hours.
The emergency driver shall accommodate an LED load with a forward voltage requirement ranging from 10 to 60 VDC. The output voltage sensing
shall be automatic and instantaneous with a resulting, inversely-proportional current to maintain constant power to the LED array with an
output tolerance of +/- 3%. The unit shall supply the rated load for a minimum of 1 1/2 hours or to 87 1/2% of rated battery terminal
voltage. The output power to the LED load during emergency operation shall be held constant 10 watts from minute one throughout the entire
emergency run time resulting in no loss or degradation of the light source during emergency operation.
The unit shall be furnished with an electronic, AC-lockout circuit which will connect the battery when the AC circuit is activated, and an
electronic brownout circuit which will enable a transfer to emergency operation when utility power dips below an acceptable level. Maximum
remote mounting distance of the emergency driver shall be 50-feet.
