The AI-302M flashing alarm indicator uses audible and visual means to display 8 alarm signals. Its hardware is based on the AI-3 platform developed by Yudian, which processes frequency and switch signals. This platform adopts the advanced modular design of the AI series instruments, offering high reliability and facilitating mass production. It is ideal for use as an alarm signal indicator on various control panels.

1. The alarm signal input circuit uses optoelectronic isolation, providing strong anti-interference capability and high reliability.

2. Utilize semiconductor planar light-emitting devices with high brightness, soft color, low power consumption, and long service life.

3. Built-in buzzer, with optional relay normally open contact alarm output.

4. Equipped with test and mute functions, operable via panel buttons or external switch connected to terminals.

5. Powered by a universal 100-240VAC input range switching power supply or a 24VDC power supply.

6. Certified under the ISO9001:2000 quality management system, ensuring reliable quality.
