Easy to install with a standard UK 3-pin plug and built with durable ABS material, it ensures reliable safety monitoring in kitchens, garages, RVs, and hospitals. ## Description - Detection gases: natural gas (methane), liquefied petroleum gas (propane, butane), artificial gas (alkanes, olefins, aromatics) - Sensor: Semiconductor Gas Sensor - Alarm concentration: 3οΌ…LEL~20οΌ…LEL - Preheat time: 3 minutes - Operating voltage: AC100V~AC240V - Frequency: 50/60Hz - Rated power: <2W Power On After powered on, the detector will make two sound β€œDi,Di” prompt tone for starting up. POWER green indicator light will steady on, and ALARM red indicator will flicker twice. Preheating mode The detector will access to the 180s' preheating mode after powering on for 3 seconds. POWER green indicator will steady on, STATE indicator will be in green flicker, and the display screen will flicker β€œ-”. Do not perform any other operations on the device during the warm-up time, because the alarm will have no response (The purpose of preheating is to adapt the gas alarm to the temperature and humidity in the installation environment). Detecting mode After finishing the preheating mode, the alarm will access to the detection mode (normal mode): Digit β€œ0” will appear on the display screen, and only POWER green indicator will steady on. Alarming mode Only the numbers 1-9 and A can be displayed on the detector screen. When a gas leakage is detected, the alarm will show different alarm status: Digit 1 or 2 displayed on screen, the POWER green indicator will steady on and the detector will not sound an alarm. Digit 3-5 displayed on screen, the STATE and ALARM indicators will flicker red at the same time, the frequency of flicker is slower, and give the moderate β€œDi...Di...” sound, and POWER green indicator will steady on. Digit 6-9 displayed on screen, the STATE and ALARM indicators will flicker red at the same time, the frequency of flicker is faster, and will make a quick β€œDiDiDi.. DiDiDi..” sound, and POWER green indicator will long light up. When the gas leakage concentration is detected to be over 9%LEL, a letter A will be displayed on the screen. The STATE and ALARM indicators will flicker red at the same time, and the frequency of flicker is the highest, the detector will make extremely pressing alarming sound. Natural gas consists of methane gas that is lighter than air. In case of the gas leakage, natural gas will rise to the ceiling and gather to the surrounding areas of ceiling. Therefore, for natural gas, the detector shall be installed 30cm below the ceiling and 1.5m distance from the radius of air source (Please install it in an appropriate location according to the height of the ceiling). LPG consists of a mixture of Propane and Butane, which is heavier than air. If the gas leaks, the LPG will fall to the ground. Therefore, for LPG, the detector should be installed 30 cm above the floor and 1.5m distance from the radius of air source (Please install it in an appropriate location according to the actual environment). Testing Method Press and hold the lighter switch, close to the gas inlet of the gas alarm and deflate slowly (Don't ignite the lighter during deflating). Please Note: Do not open the gas stove for testing without the guidance of a professional, which is quite dangerous! Package Contents: 1 x Gas Detector 1 x User Manual ## Features - {Safty Assurance} -- This Gas detector is mainly used to detect natural gas (main component: methane), liquefied petroleum gas (main component: propane, butane) and city gas (alkane, olefin, arene). When the flammable gas leakage exceeds the standard, the gas detector will issue slow or accelerated or rapid, continuous 85DB sound alarm. It can't detect CO and COβ‚‚ - {Digital display & Sound alarm} -- Number 0 showes on the gas detector indicator under normal conditions. If a flammable gas leak is detected, the indicator will showes numbers 1-9 and A. Once the concentration exceeds 3% LEL, the alarm sounds and flashes red. According to different concentration of combustible gas leak, the alarm will shows different states - {Energy saving & Durable} -- Standard British plug, not required converter, installation is extremely simple. Plastic ABS material, easy to clean. Using <2 watts of power, significant energy saving. Widely used in restaurants, kitchens, hospitals, hotels, oil plants, garages, gas stations, etc - {Test Method} -- Press and hold the lighter switch at the inlet of the methane detector and slowly deflate (do not turn the lighter on while deflating). When the concentration reaches the standard, an alarm will alarm until the volume of ambient gas falls below the alarm point. Precautions: It takes about 2-3 minutes to warm up the system, the gas test will not work during this time - {Remind for Installation} -- This gas alarm uses high quality sensors, semiconductor heating and SMT chip technology; Do not install it in a place with a lot of dust, oil smoke and water vapor, which may cause false alarms; Choose a suitable location to install the alarm according to the actual situation ## Technical Specifications | Specification | Value | |---------------|-------| | Alarm | Visual | | Asin | B07ZBCPS57 | | Best Sellers Rank | 22,190 in DIY & Tools (See Top 100 in DIY & Tools) 10 in Gas Detectors | | Brand | D MODUN | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.4 4.4 out of 5 stars (158) 4.4 out of 5 stars | | Item Weight | 150 Grams | | Manufacturer | MODUN | | Material | ABS | | Number Of Items | 1 | | Operating Humidity | 97 percent | | Part Number | BRJ-502 | | Power Source | AC | | Product Style | Compact | | Sensor Type | Gas Sensitive Semi Conductor | | Unit Count | 1.0 count | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Alarm:** Visual - **Brand:** D MODUN - **Colour:** White - **Item weight:** 150 Grams - **Material:** ABS - **Operating humidity:** 97 percent - **Power source:** AC - **Sensor type:** Gas Sensitive Semi Conductor - **Style:** Compact - **Upper temperature rating:** 50 Degrees Celsius ## Images ![LED Simple style Gas alarm - 502 - Image 1](https://m.media-amazon.com/images/I/51N6aSqjYpL.jpg) ## Questions & Answers **Q: Is it battery operated?** A: No batteries needed just plug in to socket **Q: Does it give dates for readings?

Wasn't quite sure about the reliability but had it tested in the first month and prevented elderly mother from leaving gas on overnight and literally blowing up the house.It is quite sensitive and loud but in a larger property you might not hear it everywhere so would be good if you link two or more together for extra safety.Based on that experience I would highly recommend this or a similar item anywhere where forgetful people wander around in the UK. ### ⭐⭐⭐⭐⭐ Quality *by on Reviewed in the United Kingdom 2 October 2026* Well happy,puged it in flashes for 1/2 mins then all set at 0,put a lighter beside it with no flame instantly picked up gas and alarm went of, brilliant hope it lasted,EVERY HOUSE SHOULD HAVE ONE,on sale at moment ### ⭐⭐⭐⭐ Gas alarm detector *by on Reviewed in the United Kingdom 28 February 2026* Good price. Easy to set up. Not too bulky. No alarm going off so hard to tell if it works. Must be OK. Gives you peace of mind. ## Frequently Bought Together - Gas Alarm, Natural Gas/LPG/Coal Gas Leak Detector, 3-Pin Plug-in Sensor Gas Monitor with Sound Alarm and LED Digital Display, Methane Propane Butane Combustible Gas Alarm for Kitchen Garage Hospital - FireAngel Carbon Monoxide Alarm and Detector - FA6813 10-Year Sensor Life CO Alarm for Home with AA Batteries - Travel, Portable Carbon Monoxide Detector - CO Detector Monitor with Test Button - Kidde 2030-DCR Compact 10 Year Life Carbon Monoxide Alarm with AA batteries --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/169619106-led-simple-style-gas-alarm-502](https://www.desertcart.in/products/169619106-led-simple-style-gas-alarm-502) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-10-17*
