JBF4101-Ex Explosion-proof Point Type Photoelectric Smoke and Fire Detector

Features:

1.Built-in Microprocessor: The detector collects, stores, analyzes, and evaluates data using an integrated microprocessor, enabling self-diagnosis capabilities.

2.Adjustable Sensitivity: The sensitivity of the detector can be adjusted to meet the specific requirements of different working environments.

3.Wide Applicability: The detector can respond to smoke generated by different materials, including both white and black smoke.

4.Automatic Pollution Compensation: The detector automatically compensates for pollution based on its own level of contamination, minimizing false alarms.

5.Optical Maze Self-Check: The detector performs an automatic optical maze check upon power-up. If the contamination exceeds the compensation range, it will indicate a detector contamination fault.

6.High Stability: The detector exhibits high resistance to dust adhesion, electromagnetic interference, corrosion, and environmental temperature variations.

7.Strong Moisture Resistance: The detector can withstand diverse climate conditions, ensuring reliable performance in various weather environments.

8.Intrinsic Safety: The detector is designed as an intrinsic safety device, providing enhanced protection against potential explosions.

Structure, Installation, and Wiring:

The JBF4101-Ex detector is suitable for installation in hazardous areas with flammable gases, both in industrial and residential buildings (applicable to Zone 1 and Zone 2).

The installation should comply with the relevant provisions of GB3836.15-2000 “Electrical Installations in Hazardous Areas (except Coal Mines) – Part 15: Electrical Installations in Hazardous Areas.”

It is essential to connect the detector with a safety barrier, which should be installed in a non-explosive area. Pay attention to the polarity of the circuit when connecting the safety barrier.

Each safety barrier can accommodate up to 10 explosion-proof smoke detectors. The number of detectors connected to each alarm circuit using a safety barrier should not exceed 6.

Use a dedicated electronic encoder to set the address code (1-200) for each detector.

Product Usage Scenario:

The JBF4101-Ex Explosion-proof Point Type Photoelectric Smoke and Fire Detector is specifically designed for hazardous environments with flammable gases. It is ideal for installation in industrial facilities, warehouses, chemical plants, oil refineries, and residential buildings where there is a risk of explosive gas accumulation. The detector ensures reliable and early detection of smoke and fire, providing enhanced safety and protection against potential hazards.
