Hey there, sorry to hear about the false alarms with your SIGA-HFD detector. It’s a common issue that can arise due to various factors. Firstly, ensure there’s no dust or debris buildup inside the detector, as this can trigger false alarms. Try cleaning the unit with compressed air. Also, check if there are any environmental factors like steam or cooking fumes triggering the alarm. If the problem persists, it might be a faulty detector, and you may need to replace it. Don’t forget to double-check the wiring and connections as well. Let me know if you need further assistance!
