The BY-B5508U-G/R is a robust and versatile exit sign designed for large-scale installations such as shopping malls, airports, and industrial complexes. The “G/R” in its model name signifies its availability in both Green and Red legend colors to comply with varying international and local safety codes. It operates on a 36V DC bus, allowing it to communicate directly with the MAF BY-350-DC36U control panel. This centralized architecture enables automated self-testing and real-time fault reporting. The unit features a durable, fire-retardant housing and a high-capacity LiFePO? battery that provides a reliable 3-hour emergency duration. It is UL-listed and Dubai Civil Defense (DCD) approved, making it a standard choice for high-compliance projects in the Middle East and globally.
