JBF4101-Bp

Smoke Alarm
Product Features
•   Embedded intelligent MCU inside for field data collection and analysis.
•   Automatically dust-compensation mechanism; the detector calibrates pollution degree and carries out background-value drift to prevent false alarm report.
•   Detect a variety of fires, sensitive to both white and black smokes.
•   Robust design for HW filter; prevent electromagnetic interference.
•   Strong resistance to corrosion, critical environmental (heat and humidity) and light outside.

Installation and Wiring
1) Fix the base on the wall (JBF-VB4302A base).
2) Connect the wires from the panel to the terminals L1& L2. It's polarity-free. Connect DC24V+ to terminal 24V& 24V- to G.
3) Burn ID to the detector and then mount it to the base; tighten it clockwise. 


Precautions
•   Prior to installation, write the detector and its buzzer base the same address code (1-200).The base address must be the same as that of the smoke detector attached to the base (note: the beeping base address cannot be read by the encoder).
•   As no ID for the buzzer base, it cannot be registered to panel or triggered without detector mounted.
•   The installation should be carried out with gloves to keep the detector clean.
•   It is recommended to add dust-protection cover before the inspection and acceptance, but the dust cover must be removed before the formal operation of the system.
•   Conduct smoke test regularly, ideally every six months.
