TC-ZJH6020/6021 Loop Extender 天成消防
一、TC-ZJH6020/6021Loop Extender的概述
TC-ZJH6020 loop extender (hereinafter referred to as repeater) uses AC220V for power supply and isequipped with spare battery. The electrical isolation between the input and output of the bus signal can en-hance the anti-interference ability of the whole system and has the function of extending the communica-tion distance of the detector bus.
二、TC-ZJH6020/6021Loop Extender的特点
•Bus nonpolar connection;
•Increase the bus voltage and extend the bus communication distance;
•With output short circuit detection function;
•Up to 255 devices can be attached;
•Wall-mounted structure,convenient and reliable installation.
