Wireless sound and light alarm

As an alarm output terminal, wireless sound, light, and voice alarms are usually used in conjunction with other information acquisition terminals. For example, when the production line controller detects a sudden stop of the production equipment, the corresponding alarm on the production line will sound an alarm, notifying employees on the production line of an abnormal occurrence that requires urgent handling. It supports multiple types of alarm sounds.
