TC-ZJ402 wireless signal extender

TC-ZJ402 wireless signal extender is suitable for domestic wireless alarm system and industrial wireless alarm system. The signal extender uses advanced wireless transceiver technology, built-in efficient anti-collision algorithm and can set filtering rules, so that the signal extender can work reliably in the system. At the same time, the signal extender supports multiple groups of channels, so that the signal extender can work in complex environments and in the presence of multiple control panels, realizing mutual non-interference, truly avoiding the collision of channels, and greatly improving the coverage of wireless networks.

Characteristics.

1. The power adapter is adopted, and the installation is simple and convenient.

2. SI4438 module is adopted, which has strong transmitting power and high receiving sensitivity.

3. It adopts 470Mhz frequency band and FSK coding, which has strong anti-interference ability, strong diffraction ability and long transmission distance.
