Fire Alarm System Bus Loop Extender

Product Description
TC-ZJH5008 loop extender is powered by DC24V, and the input and output of bus signals are electrically isolated, which can enhance the anti-interference ability of the whole fire alarm system and has the function of extending the communication distance of the detector bus.
II. Characteristics
1. Built-in isolated power supply with strong interference capability;
2. And the bus and the DC24V power line are non-polar connected;
3. Raise bus voltage and extend bus communication distance;
4. With output short circuit detection function;
5. Up to 255 devices can be attached;
6. Plug-in structure, convenient and reliable installation;
