CAKJ-DDL96 Comprehensive Alarm
1. Overview
CAKJ-DDL96 comprehensive alarm is a low-power, interference-free, high-volume electronic alarm device designed for central signal alarm in power systems. Using a microcontroller to simulate the sound spectrum of an electromagnetic bell and whistle, the similarity between its sound and that of an electromagnetic bell and whistle is 98%.
