HD-WAMZ
series products are intelligent devices mainly used for real-time
monitoring of the number of lightning strikes and the number of remote
signaling switches. They are divided into transmitter module HD-WAM-TZ
and receiving module HD-WAM-RZ, they both realize data transmission by
wireless technology.It is generally required to use in pairs.
HD-WAM-TZ
transmitter module is installed next to the SPD and is used to monitor
the lightning strike frequency and the change of the remote signaling
switch in real time. When a lightning strike occurs, the module can
record and display the number of lightning strikes. When the lightning
arrester fails, the module displays “OFF”. If the transmitting module
and the receiving module are paired, each transmitting module can be
coded into a different address identification code. When the number of
lightning strikes or the amount of remote signaling changes, the
transmitting module can send the address code, the number of lightning
strikes and the remote signaling switch signal to the receiving module
in a wireless form.
HD-WAM-RZ
receiving module is usually installed in the monitoring room, security
room or duty room, etc. A receiver module can monitor up to 255
transmitter modules at the same time. The module is equipped with a
2.7-inch color LCD module that can display the number of lightning
strikes and the status of the remote signaling switch of each
transmitter module in real time. If the
change in the number of lightning strikes is received, the number of
lightning strikes of the corresponding module will be updated, and a
brief prompting sound is issued at the same time. If a remote signal is
received, the remote signaling indicator of the corresponding module
will change from green to red, and an alarm sound will be issued
continuously until the damaged SPD is replaced. The receiving module is
also equipped with a data remote transmission interface, which can
connect multiple receiving modules through the 485 bus, and send all the
data further to the online monitoring real-time software or server to
achieve local single collection , partition receiving, and overall
centralized management.
