is a widely available, plug-in digital gas detector sold under various brand names including
Cleaning: Use a dry or slightly damp cloth. Do not immerse the unit in water. Storage: Store in a cool, dry place.
Proper placement is critical for the BRJ-502 to function effectively, as different gases have different weights: For Natural Gas (Methane) : Since it is lighter than air, install the detector 30cm below the ceiling and within 1.5 meters of the gas source. For LPG (Propane/Butane) : Since it is heavier than air, install the detector 30cm above the floor and within 1.5 meters of the gas source. Warm-up Period : Upon plugging it in, the device requires a 150 to 180-second warm-up
Install the detector 0.3–1.0 meters (1–3 feet) above the floor. Place it within a 1.5-meter radius of the gas source. Areas to Avoid:
Q: Is the Brj-502 Manual the same for the Brj-502A and Brj-502B models?
A: Mostly, but not entirely. The “A” version adds two additional analog outputs. Chapter 3 of the Brj-502 Manual for the “A” variant shows terminals 11 and 12 differently. Always verify model suffix on the device label.
