Bolid DIP-34A-04 Addressable Analogue Smoke Detector

DIP-34A-04 is the common version of the Bolid addressable analogue smoke detector: it measures the optical density of the air and reports the value to the panel, which lets the system tell real smoke from a dusty chamber. The detector is powered from the loop and reports its exact location, so an alarm points at a specific room. Used in offices, schools, administrative and industrial buildings.
