The AWZ-535 is a passive device and allows to distribute the power supply. For more devices than 4, the devices can be connected in parallel on the same terminal. An unquestionable advantage of employing the AWZ-535 in monitoring systems powered from a central point is additional tamper protection.
When one of the output is fault, the AW output and LAW LED are on. AW output can be used to remote control of the LB5/AW state, for example external optical signaling.
