Product Description | Model Number: BRJ-502D |
It is a self-contained flammable gas alarm, adopts international advanced gas sensing technology, and uses cost-effective microprocessor as the control core. It is a small gas safety protection product suitable for use in the home. It is used for continuous detection of indoor gas. Leakage concentration, the detector emits an audible and visual alarm when the leak concentration reaches the set value. When the indoor gas concentration is lower than the alarm set value, the detector automatically returns to the normal working state, which can avoid the occurrence of personal injury or death, property loss accidents such as poisoning, explosion, fire caused by flammable gas leakage.
There are three types of plugs, including British regulations, European regulations and US regulations, please place a note,

Technical indicators
Detection gas: liquefied petroleum gas, natural gas, artificial gas
Working voltage: AC100V~AC240V 50/60Hz
Rated power: lt, 4W
Alarm concentration: Liquefied petroleum gas: 0.1~ 0.5% Natural gas: 0.1~ 0.3% Gas 0.1~ 0.5%
Alarm volume: ≥85dB (3 meters away from the product)
Operating environment: -10 ° C ~ 50 ° C, relative humidity lt, 97% RH
Storage temperature: -25 ° C ~ 55 ° C
Display window number is from 1~9
Shows the change in gas concentration. When the display window is 3, 4, 5, the STATE red light is on, and the alarm emits a slow �-�... sound,
When 6, 7, 8, 9 is displayed, the STATE red light is on, and a quick ���-���... sound is emitted.
Alarm status:
When the gas concentration reaches the preset value, the display window shows the concentration as A, the product alarm, and the STATE indicator is red.
The ALARM indicator lights up. When the concentration is lower than the alarm set value, the alarm will automatically return to normal operation.
