1. Strong electric protection circuit, to prevent field bus misconnection AC220V + 20% cause product damage.
2. Non-polar two-bus system, ultra-low power design, without additional 24V power supply.
3. High brightness and sound pressure are achieved by using ultra-bright LED, special buzzer resonator and patent driving circuit.
4. Adopt non-stripping wiring mode and snap-on installation mode, which makes field installation convenient and reliable.
5. Set alarm mode freely. It can alarm both acoustically and optically, and it can also alarm independently.
6. It has two alarm tones and is suitable for different workplaces.
7. It can be set flexibly as non-coding acoustooptic alarm.
