Hey there! False alarms with the Hochiki ALN-V system can be quite frustrating but let’s see if we can sort it out. Firstly, false alarms can often be triggered by environmental factors such as dust or insects in the sensor chamber. Try cleaning the detector chamber and ensuring there are no obstructions. Also, check for any loose connections or wiring issues, as these can also lead to false alarms. If the problem persists, it might be worth considering a software update or contacting Hochiki technical support for further assistance. Hope this helps!
