Understanding the data on the digital screen, the meaning of each light, and the exact physical installation path is critical for preventing gas poisoning, fires, and explosions. Technical Specifications Specification BRJ-502 / BRJ-502D Detectable Gases
: Install the unit 1–3.3 feet (0.3–1.0m) below the ceiling and within a 5-foot (1.5m) radius of the gas source (e.g., your stove or heater).
: Mount it within a 1.5-meter (5 feet) horizontal radius from the appliance or gas pipeline. 2. LPG, Propane, & Butane Monitoring (Heavier than Air) Liquefied petroleum gases sink down to floor levels.
The Brj-502 Manual recommends:
Shows the target temperature target (Set Value) or parameter codes during configuration.
The BRJ-502 is a functional accessory used in conjunction with rail-mounted terminal blocks. Its primary function is to create electrical bridges between adjacent terminals, facilitating common potential distribution.
: Detects natural gas (Methane), LPG (Propane/Butane), LNG, and coal gas. Brj-502 Manual
Secure the BRJ-502 using four M8x1.25 bolts through the base flange (dimensions: 124mm x 88mm). Torque to 18 Nm. Do not use thread locker on the center bolt—it grounds the static discharge circuit.
The Brj-502 supports two programming methods:
: You can test the unit by slowly releasing a small amount of gas from an unlit lighter near the sensor. Never use a gas stove for testing without professional guidance. Understanding the data on the digital screen, the
The series comes in a few different models, so it's helpful to identify which one you have:
Proper setup and calibration are essential for obtaining accurate, traceable measurements from the BRJ-502. A typical workflow involves the following steps:
