The System Sensor 5624 is a photoelectric smoke detector known for its reliability, but false alarms can still occur due to various reasons. Firstly, ensure the detector is installed properly, away from sources of heat or steam that could trigger false alarms. Check for any obstructions such as dust or debris that might interfere with the sensor’s operation. Additionally, verify that the detector’s sensitivity setting is appropriate for the environment it’s installed in. If the issue persists, it might indicate a malfunctioning detector that needs replacement. Contact our technical support team for further assistance.
