Product selection can be reviewed by installation environment, gas type and target-market requirements.
Answer Summary
Hanwei Smart Gas provides the KB180 Gas Detection Controller for compact industrial and commercial gas alarm systems. It accepts up to eight compatible 4-20mA fixed detectors and provides LCD status indication, local audible and visual alarms, two dry-contact relays and a DC24V pulse-valve output. RS485/Modbus supports monitoring-system integration. The controller belongs in a safe indoor area, while field detectors are selected for the actual gas and site conditions. Detector compatibility, valve type, wiring, output loads and certification coverage require confirmation for the project and target market.
Product Overview
KB180 coordinates up to eight compatible 4-20mA fixed gas detectors in a compact alarm control system. LCD and status indicators provide local visibility, while audible and visual alarms, two dry-contact relays and a pulse-valve output support response-device integration. RS485/Modbus provides a connection to an upper monitoring system. This is a safe-area controller rather than a field gas detector. Confirm detector power demand, cable design, output loads and the required response sequence before planning shut-off or ventilation linkage.
Product category
Gas Detection & Alarm Control Systems
Small commercial premises, commercial kitchens, utility rooms, small station areas and compact multi-point combustible gas monitoring projects.
Controller-level alarm judgement with LCD / LED status indication
Local sound and light alarm handling for duty-room operation
Two dry-contact relays and a DC24V pulse-valve output for compatible devices
RS485 / MODBUS upload, subject to monitoring-system compatibility confirmation
Application Fit & Installation Boundary
Select products for the installation environment, gas type and system role.
Application fit
KB180 supports compact gas detection controller applications where 4-20mA fixed detectors and local response devices need coordinated alarm handling.
Installation context
Wall-mounted installation in a safe indoor area such as a monitoring room or duty room. Connected detectors are installed near the relevant gas-use or potential leak locations according to site assessment.
Selection boundary
KB180 is a controller, not a gas detector, gas meter, household alarm, field probe or inline pipeline device. Point count, 4-20mA transmission distance, linkage output and certification should be confirmed by model and market.
Typical Applications
Common gas safety scenarios where this product category can support monitoring, alarm verification or response workflows.
Small restaurants and small commercial premises gas monitoring
Commercial kitchen and gas equipment room alarm control
Shopping mall or underground corridor gas leak alarm projects
Compact 4-20mA detector plus controller packages
Local alarm, relay linkage and monitoring-record workflows

FAQ
Common questions for early product selection and project discussion.
Does KB180 detect gas directly?
No. KB180 is a gas detection controller. Gas detection depends on connected 4-20mA gas detectors, while KB180 handles controller-level alarm judgement, display, output and upload workflows.
Where should KB180 be installed?
KB180 is intended for wall-mounted installation in a safe indoor area such as a monitoring room or duty room. It is not an explosion-proof field device and is not intended for hazardous zones, outdoor rain exposure or installation directly beside a gas pipeline. Confirm the site and installation arrangement before use.
Can KB180 link with fans or shut-off valves?
Relay and optional pulse-valve outputs require compatibility checks for the selected fan, shut-off valve or other response device. Confirm the output configuration, device models, wiring and project design before use.
Can KB180 connect to an upper monitoring system?
RS485 / MODBUS upload is an integration option. Confirm model support, monitoring-system compatibility, data mapping and the integration scope before project use.
Are certifications available?
Certification availability varies by product and target market. Contact us for confirmed specifications.
