The BRJ-502 (also referred to as BRJ-502D or BRJ-502E) is a plug-in combustible gas detector designed for residential and recreational vehicle (RV) use. It is sold under various brands, including Eksahol, Firlarm, CPVan, and D MODUN. Key Features
Target Gases: Detects natural gas (Methane), LPG (Propane/Butane), LNG, and coal gas.
Alarm System: Features a loud 85 dB audible siren and a red flashing LED.
Visual Display: Equipped with an LED digital display that shows real-time gas concentration levels (0–9 and 'A').
Sensor Technology: Uses a semi-conductor sensor with an intelligent MCU (Micro Control Unit) to monitor gas concentration. Quick Setup & Operation Placement:
Natural Gas (Lighter than air): Install 1–3.3 feet (0.3–1.0 m) below the ceiling and within 5 feet (1.5 m) of the gas source.
LPG/Propane (Heavier than air): Install 1 foot (0.3 m) above the floor and within 5 feet (1.5 m) of the gas source.
Power On: Plug the device directly into a standard AC wall outlet (110V–220V).
Warm-up Mode: The device requires a 150–180 second (2–3 minute) warm-up period.
The LED will display a blinking dash ("-") or changing characters during this time.
Important: The detector will not sense gas until this period is complete.
Normal Mode: Once ready, the display will show "0" and the green "POWER" light will remain steady. Understanding Display Codes Action Required 0 Normal operation; no gas detected. 1–9 Low to moderate gas leak detected. Ventilate area and check gas appliances. A Dangerous gas leak concentration detected. Evacuate immediately and call emergency services. Maintenance & Safety
Testing: Periodically test the device to ensure the audible and visual alarms are functional.
Cleaning: Wipe the exterior with a soft, dry or slightly damp cloth.
Avoid Contaminants: Do not spray cleaning chemicals, insect sprays, or paint near the sensor, as these can cause malfunctions or permanent damage.
Limitations: This device detects combustible gases only; it is not a carbon monoxide (CO) detector.
Installation: Plug the device directly into a standard AC power socket (AC 100V–240V).
Warm-Up Period: After plugging it in, the device requires a 3–5 minute warm-up period before it can accurately detect gas.
During this time, the "STATE" light will flash green and the screen will show flashing characters.
Ready State: Once preheating is complete, the display will show "0" and only the green "POWER" indicator will remain steady. Indicator & Alarm Meanings
The device uses a digital display and three indicators (POWER, STATE, ALARM) to communicate gas concentration levels: 0 (Normal): No combustible gas detected.
1–2 (%LEL): Low concentration; only the green POWER light is on. No audible alarm sounds.
3–5 (%LEL): Moderate concentration. The STATE and ALARM lights flicker red slowly with a moderate "Di... Di..." sound.
6–9 (%LEL): High concentration. Lights flicker red quickly with a rapid "DiDiDi..." sound. Even with proper care, users may encounter issues
A (>9% LEL): Critical concentration. The screen displays "A," and the device emits an extremely pressing audible alarm. Placement Guidelines
For effective detection, the unit must be placed according to the type of gas being used:
For Lighter-than-Air Gases (e.g., Natural Gas, Methane): Install 1–3.3 feet (0.3–1.0m) below the ceiling and within 5 feet of the gas source.
For Heavier-than-Air Gases (e.g., LPG, Propane): Install 1 foot (0.3m) above the ground and within 5 feet of the gas source. Safety & Maintenance
(also sold as BRJ-502D) is a plug-in digital gas leak detector designed to monitor for flammable gases including Natural Gas (methane), (propane, butane), and Urban Coal Gas Key Specifications Sensor Type: Semiconductor gas sensor. Power Source: AC 100V – 240V, 50/60Hz. Warm-up Time: Approximately 3 minutes (180 seconds). Alarm Volume: Digital Display: Shows gas concentration levels from 0 to 9 or "A". Indicator Lights & Display The unit features three primary status indicators: POWER (Green): Stays on to indicate the unit is receiving power. STATE (Yellow/Green): Flashes during the warm-up period. ALARM (Red): Flashes when gas concentration reaches dangerous levels. Display Value Status Description Normal; no combustible gas detected. Low concentration; POWER light on, no audible alarm.
Medium concentration; slow "Di...Di..." alarm sound; ALARM and STATE lights flash. 6–9 or A
High concentration; rapid, continuous whistling alarm sound. Installation Guidelines Placement depends on the type of gas you intend to detect:
(often listed as the BRJ-502D) is a plug-in combustible gas detector designed for home safety, commonly sold under brands like
. Its primary function is to provide continuous monitoring and early warning for leaks of natural gas, propane (LPG), and coal gas. Core Functionality & Display
The device uses a semiconductor sensor and an intelligent microprocessor (MCU) to detect gas concentrations. LED Display
: Shows the real-time gas concentration. In normal mode, it typically displays "0". Three Indicators POWER (Green)
: Remains lit when the device is properly connected to AC power. STATE (Yellow/Orange) : Flashes during the initial warm-up period. ALARM (Red) : Flashes when a gas leak is detected. Audible Alarm
: Once gas levels reach a preset threshold (typically around 3% LEL), a loud siren (≥85dB) sounds to alert residents. Setup and Installation
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
period. During this time, it performs a self-test and will not detect gas. Operating Modes Display/Indicator Behavior Display flashes; STATE light is on or blinking. Normal (Search) Display shows "0"; POWER light is steady green.
Display shows numbers 1-9 or "A" based on concentration; ALARM light flashes; siren sounds. Maintenance and Safety Precautions
: 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.
: Wipe the exterior with a soft, dry cloth. Do not spray cleaning chemicals, insect sprays, or silicones directly on or near the detector, as these can damage the sensor or cause false alarms. Power Outages : Most models are strictly plug-in and do not have a battery backup . If the power goes out, the device will not function.

Even experienced operators encounter faults. The Brj-502 Manual contains a dedicated troubleshooting matrix. Below are the most common error codes:
If an error is not listed in the manual, look for a “Diagnostic Mode” described in Chapter 8. This allows you to view raw ADC counts for inputs and manually toggle outputs.
The Brj-502 Manual dedicates a full chapter to the front panel because a single incorrect keypress can alter a running process.
Press and hold Mode for 5 seconds. The display will show SAVE. Press Set to write all changes to EEPROM. The device then reboots.
Without the Brj-502 Manual, these parameters are just cryptic codes. The manual decodes each one with practical ranges and warnings.
