·Standards: GB4716-2005 “Point-type Temperature Heat Detector,” GB3836.1-2010 “Electrical Apparatus for Explosive Gas Atmospheres – Part 1: General Requirements,” GB3836.4-2010 “Electrical Apparatus for Explosive Gas Atmospheres – Part 4: Intrinsically Safe ‘i’ Equipment.”

Structure, Installation, and Wiring:

The detector is equipped with a dedicated electronic encoder for setting the address code (1-200).

It is suitable for installation in hazardous areas where flammable and explosive gases are present, including industrial and residential buildings (applicable to Zone 1 and Zone 2).

Installation should comply with the relevant regulations of GB3836.15-2000 “Electrical Installations in Hazardous Areas (Excluding Coal Mines).”

A safety barrier must be installed, which should be placed in a non-explosive area. Pay attention to the polarity when connecting the circuit.

The number of explosion-proof smoke detectors connected to each safety barrier should not exceed 10, and the maximum number of safety barriers per alarm circuit should not exceed 6.

Product Usage Scenarios:

1.Industrial Facilities: The JBF4111-Ex Heat Detector is ideal for use in industrial environments with hazardous areas, such as chemical plants, oil refineries, and manufacturing facilities.

2.Commercial Buildings: It can be installed in commercial buildings, including shopping malls, hotels, and office complexes, to provide reliable fire detection in areas where flammable gases may be present.

3.Residential Complexes: The detector ensures the safety of residential buildings, including apartments and condominiums, by effectively monitoring temperature changes and detecting potential fire hazards in proximity to gas appliances or storage areas.

4.Warehouses and Storage Facilities: This heat detector can be deployed in warehouses and storage facilities that handle flammable materials, providing early detection and alerting personnel to potential fire incidents.
