Emergency Lighting Products
Can IOTA Emergency LED Drivers be installed in the field?
Yes, most of IOTA’s “Constant Power” Emergency LED Drivers are UL Listed for field or factory installation. This will be noted on the product specifications.
Which Emergency LED Drivers are “Constant Power”?
What is “True Constant Power”?
IOTA’s patented Constant Power design allows IOTA “CP” Emergency LED Drivers to deliver a constant wattage to the LED array, providing non-diminishing light output for the full emergency runtime. Despite claims to the contrary, not all “Constant Power” emergency LED drivers from other manufacturers deliver constant power output. Some classify the output as “regulated” which means the output power is only constant for a limited amount of time but is then reduced to protect battery discharge. Refer closely to emergency driver specifications – if the amperage of the emergency driver states a single value, then it is impossible for the output wattage to remain constant.
Are 3D Files Available?
Many of IOTA’s product webpages include downloadable 3D STEP files in the “Technical Files” section. If a STEP file is not available for a particular product, contact IOTA Tech Support and they would be happy to generate one for you.
Which emergency solutions provide full light output?
IOTA’s IIS Inverters are designed to supply AC voltage to the luminaire and therefore will enable full light output in emergency conditions.
Do I still need to keep written test records when using Self-Diagnostic products?
Depending on the type of Self-Diagnostic product, written test records are still necessary to meet emergency lighting code requirements. Many Self-Diagnostic products, such as emergency LED drivers, use their illuminated test switch/indicator to display the status of monthly or annual tests. However, these units will not generate a written record of the test’s completion. It is the responsibility of the facility manager to periodically inspect the test switch to record the operating status of the unit. That being said, IOTA does offer Central Inverter products that both test the emergency function and log the test results.
Can I find the lumen performance of an IOTA Emergency LED Driver?
IOTA’s Constant Power design allows lumen performance to be calculated by multiplying the output rating of the IOTA Emergency LED Driver (ex: 5 watts) by the fixture’s lumen efficacy (ie: lumens/watt). For example, a 5-watt emergency LED Driver installed in a luminaire with an efficacy of 100 lumens/watt will provide 500 lumens in emergency conditions (5 watts * 100 lumens/watt = 500 lumens in emergency).
I cannot find a wiring diagram for my application. Can you provide one?
IOTA’s Tech Support team will be happy to provide a wiring diagram to suit your particular application if one cannot be found online.
How can I find out which Top Mount Kit (KIT TMK) or Remote Test Kit (KIT RTK) is appropriate for my model?
What is an “ALCR Device”? How is it different than a transfer switch?
ALCR stands for “Automatic Load Control Relay” and ALCR devices differ from a transfer switch in how they manage power in emergency conditions. A UL 1008 transfer switch is designed to switch between utility power and an emergency power source during emergency conditions. An ALCR device does not switch between power sources, but instead senses the presence of utility (normal) power and “passes through” emergency power to a luminaire, regardless of the position of a wall switch or other on-off control device. IOTA’s ETS Series Emergency Control Devices are UL 924 listed as an ALCR device.

Should I use a volt meter or hydrometer when checking my battery level?
You should never let your batteries get below the 20% capacity level.
NOTE: To test a battery at rested state, disconnect the positive lead from the battery for approximately 20 to 24 hours.
Why do I read less voltage at the battery than I do at the battery charger?
