Wireless sound and light alarm
Product Description
As an alarm output terminal, the wireless sound and light voice alarm
is usually used in conjunction with other information collection
terminals of our company. For example, if the production line controller
detects that the production equipment suddenly stops, the alarm on the
corresponding production line will alarm and notify the product. An
abnormality occurs among online employees and requires emergency
treatment. Supports multiple types of alarm sounds. Cooperate with
wireless SCADA ad hoc network host (HTTP/MQTT) orUSB to wireless SCADA gateway (AT command), users can quickly generate their own wireless application solutions.
