The BY-B2108E-S24L-C is an architectural “blade-style” exit sign designed for modern commercial interiors where aesthetics and reliability are equally important. The “S24L” designation refers to its 24-meter viewing range and the use of Lithium (LiFePO?) battery technology. This unit is a Maintained luminaire (permanently ON) that provides a reliable 3-hour emergency duration during power outages. It is equipped with an integrated Self-Testing module that automatically performs routine diagnostic checks on the battery and LED strip, reporting status via a multi-color LED indicator. Its slim aluminum and polycarbonate construction allows for a discreet “floating” appearance when ceiling or wall-mounted.
