•Adopt two-bus system:two-bus without polarity signal
•Built-in microprocessor,with intelligent judgment ability.
•The address is set through electronic coding,and there is no dial switch,which increases the airtight proper-ty in structure.
•With self-diagnosis function to ensure its reliable operation
•The status signal value can be provided,which intuitively reflects the current working status of the sounderstrobe.
•Multi-level filtering with software and hardware can effectively suppress interference signals
•When the sounder strobe is activated,it can emit strong light and produce a harsh alarm sound.
