Our technician at firealarm.com suggests checking a few possible causes for the intermittent alarms on your Kidde KI-OSHD system. Firstly, ensure that there are no obstructions or debris interfering with the sensors or detectors. Next, verify that the power supply to the system is stable and not experiencing fluctuations. Additionally, check if there are any loose connections or faulty wiring that could trigger false alarms. If the issue persists after these checks, it may be necessary to contact Kidde’s technical support for further assistance or to schedule a maintenance visit.
