For loud or harsh environments, such as industrial complexes, transit facilities or bridges, this call box features a handset and noise-canceling microphone for private calls. It also is hardened, with durable marine-grade stainless steel construction and additional security with a latching door. An ultra-bright LED blue light can be deployed with the box, and the unit can be programmed to flash the light when the handset is lifted off the hook, attracting attention to the scene.
