JBF4111 Point-Type Temperature-Sensitive Fire Detector (A2R)
Key Features:
1.Built-in microprocessor enables data storage and analysis for enhanced functionality and self-diagnosis.
2.A2R-class detector with differential temperature alarm capabilities.
3.Fire alarm confirmation light utilizes a light guide column for 360-degree visibility.
4.Utilizes a glass-encased temperature-sensitive resistor for rapid temperature response.
5.Outputs temperature rise and fall curves for on-site temperature monitoring via a controller.
6.High stability with strong resistance to electromagnetic interference, corrosion, and environmental temperature impacts.
7.Excellent resistance to humid and hot conditions, suitable for various climatic environments.

Structure, Installation, and Wiring:
1.Secure the detector base (JBF-VB4301B) onto the embedded box using two M4 screws.
2.Use ZR-RVS-2×1.5mm2 twisted pair cable, connecting the loop’s two wires to terminals L1 and L2 without polarity.
3.Use a specialized electronic encoder to assign a device address (1-200) to the detector.
4.Insert the detector into the base and tighten it clockwise.
5.It is recommended to wear gloves during installation to keep the detector’s housing clean.
