The first is the electrical DC power used to energize the lights. As such, the FireFly system’s limitations are best described by looking from the perspective of the FireFly UPS control panel. The serial communications and DC power would still pass through to the next FireFly lights and all units downstream would remain operational.Įach string of FireFly lights, powered from the FireFly UPS control panel, can support up to 50 individual FireFly lighting modules. Only the bank of three LEDs would be affected, meaning that 15 of the 18 LEDs in the module would remain operational. If an individual LED on the FireFly lighting module PCB fails It will also automatically apply the correct colour setting and mode of operation.
When the damaged module is replaced, the system will automatically discover and position the new unit using the software user interface.
Immediately after the unit is damaged, a fault alarm is issued on the FireFly lighting control application to allow for a quick response time. If a FireFly module gets crushed, smashed or fallsĪll FireFly lights down-stream from the damaged unit would continue to run for up to three hours due to their internal battery, and then go offline. The system has two failure modes to account for different scenarios:
The design of the FireFly LED lighting module PCB circuit enables the failsafe pass-through of both the DC power and the RS485 serial communications.
