The alarm wasn’t sounding. That was the problem. If there was gas, the Pulsar should have been screaming, flashing red, shutting down the heavy steel doors behind Elias to contain the spread. Instead, it was just humming quietly, displaying the error code, essentially comatose.
The transmitter and receiver must be mounted on stable structures, such as steel columns, to prevent misalignment caused by vibration or thermal expansion. The optical path must be clear of obstructions. Electrical Connections drager pulsar 7000 manual

The series uses infrared absorption spectroscopy to detect a wide range of gaseous hydrocarbons, from methane to hexane. Detection Range: Covers distances from 4 meters up to 200 meters depending on the model. Response Time ( Extremely rapid detection in less than 2 seconds under normal conditions. Environmental Durability: Operates between negative 40 raised to the composed with power C positive 60 raised to the composed with power C negative 40 raised to the composed with power F positive 140 raised to the composed with power F protection rating. Signal Output: Features a standard 4 to 20 mA analog output and digital communication. Operational & Maintenance Highlights
The Pulsar 7000 is an open-path infrared (IR) detector, meaning it uses a beam of infrared light to detect gas clouds between a transmitter and a receiver, covering distances up to 200 meters.
