OSE-SPW | Vesda Xtralis OSID-DE Standard Power Wired EmitterDescription The Vesda Xtralis OSE SPW is a standard power wired emitter designed for use with the OSID DE (Open area Smoke Imaging Detection) system. It emits dual wavelength coded light beams in both ultraviolet (UV) and infrared (IR) frequencies, enabling reliable smoke detection over long distances. Engineered for precision and resilience, it ensures stable performance in large, open environments where traditional point detectors are impractical.
