World’s Smallest Conbustible CH4 Gas Leakage Alarm JKD-819

Gas Alarm JKD-819 Introduction

The product is a smart combustible gas detector with long life sensor, microprocessor control, support displaying of the gas concentration.

This alarm is the smallest gas detector we have ever made,Perhaps in the world for the mass-production alarms.

It’s plug-in type but NO-CABLE! the weight is just 80g and you can put it in any corner in your testing area.

When trigge the gas detector, it will alarm with build-in siren. This detector adopt semiconductor sensor which is stable and reliable.

It keeps the place safe from the threats of combustible gas (such as liquefied petroleum gas, natural gas methane,etc.)

Operation Guide

1. FIRST START
Connect the detector to 90V-240V power,the green indicator lights up, the green light around the black glass flashes,and the display begins a 3-minute countdown to warm up
2. ALARM
When the gas concentration is over 6%LEL , the buzzer will make a continue sound as “Di Di Di” and the red indication light will flash at the same time. At this moment please close the gas valve and open the door to clear the gas and inform the professional to check.

If it is false alarm, please check whether the installation place is suitable or not.

1. Please confirm the induced gas is heavier than air or lighter than air, the gas is heavier than air: LPG etc the gas is lighter than air: natural gas, marsh gas and etc.

2. Choosing the suitable position to install the Detector according to the gas specific gravity.

Detecting the gas heavier than air: Installation height from floor,0.3-1.0m, semi-diameter to gas source<1.5m;

Detecting the gas lighter than air, Installation height from celling, 0.3-1.0m,semi-diameter to gas source<1.5m

3. Avoid installing the detector close to the following
sources of interference: direct air flow from vents, fans doors, windows, sources of steam, oil vapor, etc.

4. All wires installation must accord with the national and ocal effective laws and criteria, The wires must have the suitable size and colorful marks for avoiding connecting error.And unsuitable connection of wires will result in the alarm error while gas leaking happened.
