Product Description
JT-JHDZ-1 type gas alarm is an intelligent independent gas alarm with a measurement range of 0-100%LEL, using microprocessor control, using semiconductor sensor, high sensitivity, long service life and other characteristics.
When the detection concentration reaches the alarm setting value, emit the acoustic and optical alarm (if equipped with a cut-off valve, it can automatically conduct the switch type operation). The product is mainly used in places where combustible gas (such as liquefied petroleum gas, natural gas, biogas, etc.) may leak, to detect whether combustible gas leaks, send out alarm signals and control signals, and remind personnel to take timely measures to ensure personal and property safety.
- Using a high-performance gas sensitivity sensor;
- Multiple gas types of sensors are interchangeable;
- Fast response time, small zero drift, high accuracy, low power consumption, long service life;
- Microprocessor control, MP thin film process design;
- To each the alarm setting point, emit sound and light alarm;
- Can output control signal control solenoid valve and other equipment.

Installation instructions
(1) Installation site
- Alarms suitable for LPG should be installed at less than 30 cm from the ground, within 24 meters of the radius of the gas source, and well ventilated;
- Alarms suitable for natural gas and artificial gas should be installed at less than 30 cm from the ceiling, within 24 meters from the radius of the gas source, and well ventilated.
(2) Installation mode and power supply
- Determine the installation position, secure the alarm hanging panel on the wall, and then hang the alarm on the hanging panel.
- After turning on the power supply, the green light flashes, and the yellow light and the red light is always on. After 3 minutes, the green light stops flashing and is in the normal light state, while the other lights extinguish, and the alarm enters the normal working state.
- Installation precautions
- The alarm shall be installed for easy observation and easy jet inspection
- The alarm shall be installed in a room with gas tools and possible gas leakage;
- Alarm cannot be installed in lampblack, water vapor is directly smoked position, if: between hearth and smoke lampblack hood
- The alarm shall not be covered by other objects
- No alarm installation position: corner, cabinet, and other positions where the air is not easy to circulate
- Never drop and impact the alarm during installation
