TX7130 Conventional Reflective Beam DetectorDesigned for protecting large, open plan areas with high ceilings, this reflective optical beam detector works on the principle of infrared beam obscuration. It uses a single ended design with a reflector to notify a fire alarm panel when the beam is interrupted by smoke particles. Featuring a built in laser pointer and digital display guide, it offers a uniquely user friendly alignment and commissioning process. Key Specifications: Model: TX7130
