Note: sample gas CH4
Installation Location:
- The gas detector is fixed within a radius of 1.5m from the gas source.
- If used to detect LPG, the JDY-336 must be installed above the groud about 0.3m~1.0m because LPG is heavier than air.
- If used to detect natural gas or coal gas, the JDY-336 must be installed next to ceiling about ≤ 0.3m because those gases are lighter than air.
- It can not be fixed above gas cooking stove or around exhausting fan, door & window brink or watery bathroom.
- Connection method: The terminal board CON1 connects the AC220V, socket CON2 yellow line is the common interface. The terminal board blue line is the constant-closing joint. The terminal board black line connects the 12VDC cathode. The terminal board red line connects the 12VDC anode.
Working and testing procedure:
- The JDY-336 enters into self-testing state just when electrified, then the red LED flashes for one second, meanwhile the buzzer sounds "di", which means the circuit works normally. Then the pre-heating begins, the green LED flashes, and the green LED lights about three minutes later, then it works well.
- Click the self-test button, the red, green, yellow light lights cycle, flash and sound alarm stops after 15 seconds.
- The green LED flashes under the normal working state, and the circuit keeps still inspecting state. The red LED shines after the JDY-336 detects the gas, meanwhile the buzzer alarms and outputs the network alarm signals. The JDY-336 resumes the normal working state automatically after the flammable gas is abviated.
- If the buzzer keeps alarmingg and the red LED doesn''t shine, it means the JDY-336 damaged, please cut off power.
Warning Solutions:
Once flammable gas density reaches or exceeds alarm concentration, the alarm will sound. To disalarm it, you should take the following steps:
- Close pipeline gas bolt immediately.
- Open windows to ventilate room.
- Extinguish all fire-sources and flammable articles(forbid flicking lighter or striking a match).
- Avoide switching on/ off any appliance.
- Check the reasons of leak gas. Then inform concern department and professionals as soon as possible.
