Fire Fighting Enterprises of Hitchin, Hertfordshire, United Kingdom, offers smoke detectors that use optical beams to detect smoke in large areas. The new FIRERAY 3000 infrared optical beam smoke detector is unobtrusive and easy to install, especially where ceiling mounting is unavailable. It is ideal for applications where the beam path is narrow or where the building includes reflective surfaces that might cause complications. A visible targeting laser housed in the receiver head aids initial placement and setup. Both detector heads have integrated alignment thumbwheels for adjustment.
