The first generation of intelligent wireless monitoring module
HD-WAM series product is a device that is mainly used to provide sound and indicator alarms when a lightning arrester with a remote alarm function fails.It adopts wireless transmission method,which consists of wireless alarm monitoring module HD-WAM-T and wireless alarm module HD-WAM-R. HD-WAM-T is a companion device for monitoring the status of remote signaling of a group of (four) surge protectors. It uses a voltage detection method to obtain surge protection remote signaling and identify good and bad. When any of the protectors fails, the voltage check circuit will trigger off and send an indicator alarm, and also send the alarm signal wirelessly. HD-WAM-R is a remote receiving device compatible with HD-WAM-T. Once it receives a valid alarm signal, it will send an audible and visual alarm.
