Description
The JT-AT2004BII is an energy-saving household bus-type combustible gas detector with a unique 2-wire design, integrating power supply and signal transmission without external 24V power, simplifying wiring and reducing installation costs. Advanced temperature compensation adjusts detection parameters to ambient temperature, ensuring accurate, stable detection of combustible gases and avoiding false/missed alarms. It has an automatic lifetime expiration reminder to prevent risks from expired equipment. A built-in black box records alarms, faults, and logs for quick troubleshooting. Made of V0-rated flame-retardant material with IP31 protection, it resists dust and light water splashes. As a bus-type detector, it has good expandability, connecting multiple units for centralized monitoring, suitable for larger households or multiple gas usage points.

Frequently Asked Questions
Q
Does the JT-AT2004BII require an external 24V power supply?
No. The JT-AT2004BII features a unique 2-wire design that integrates both power supply and signal transmission into a single connection. No external 24V power supply is needed, which significantly simplifies installation and reduces wiring costs.
Q
How does the temperature compensation feature work?
The advanced temperature compensation system continuously monitors the ambient temperature and automatically adjusts the detector's sensitivity parameters accordingly. This ensures consistently accurate and stable combustible gas detection across varying environmental conditions, effectively reducing the risk of false or missed alarms.
Q
What does the lifetime expiration reminder do?
The device includes an automatic lifetime expiration reminder that alerts users when the detector is nearing the end of its service life. This helps ensure the unit is replaced on time, preventing potential safety hazards associated with using an expired or degraded gas detector.
Q
What information does the built-in black box record?
The built-in black box logs all alarm events, fault occurrences, and operational history. This data can be reviewed for quick and efficient troubleshooting, helping technicians and users identify issues and maintain the device with greater accuracy.
Q
Is the JT-AT2004BII suitable for use in humid or dusty environments?
Yes. The detector is constructed with V0-rated flame-retardant material and carries an IP31 protection rating, making it resistant to dust ingress and light water splashes. This ensures reliable performance in typical household kitchen or utility environments.
Q
Can multiple JT-AT2004BII units be connected together for larger properties?
Yes. As a bus-type detector, the JT-AT2004BII supports connection of multiple units within the same system, enabling centralized monitoring across an entire property. This makes it well-suited for larger households or locations with multiple gas appliance usage points.
