JBF4112 Point-type Household Temperature Fire Detector (A2R)

With its integrated sound alarm feature, the device emits audible alerts in case of a fire emergency. It utilizes a light guide column and possesses excellent electrostatic discharge resistance. The temperature-sensitive resistor is encapsulated with epoxy resin, ensuring fast temperature response.

The device provides temperature rise and fall curves, allowing real-time monitoring of temperature changes on-site through a compatible controller. It boasts high stability and is resistant to dust accumulation, electromagnetic interference, corrosion, and environmental temperature fluctuations. Its strong moisture resistance enables it to adapt to various climatic conditions.

Manufactured using surface-mount technology (SMT), it ensures high-quality assembly and reliable performance.

Structural Features, Installation, and Wiring:

1.Secure the detector base, JBF-VB4301B, onto the embedded box using two M4 screws.

2.Connect the loop wires, ZR-RVS-2×1.5mm2 twisted pair cable, to terminals L1 and L2 without polarity distinction.

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

4.Insert the detector into the base and tighten it clockwise.

5.It is recommended to wear gloves during installation to maintain the cleanliness of the detector’s housing.

The Fire Detection and Alarm Device is a reliable and efficient solution, meeting the requirements outlined in GB22370-2008 and GB4716-2005 standards for household fire safety systems and point-type temperature fire detectors, respectively.
