Collision Alert [CA] alarmed multiple times between Aircraft X and a target indicating beacon code [XXYY]. First alert occurred when Aircraft X was approximately ENM080050 at FL270. Aircraft is ADSB equipped. These alarms appeared to be conflicts between the aircraft's two transponders.These nuisance CAs occur multiple times each day; and have an additive desensitizing effect on controllers and CICs/FLMs (Controller in Charge/Frontline Manager). This leads to a potential reduction in response time to legitimate CAs. I recommend an analysis of our display and data processing systems to determine the cause of these spurious alerts; and applying software patches or equipment upgrades as necessary to resolve them.
FAI FLM (Frontline Manager) reported of collision alerts that are caused by the aircrafts ADS-B. FLM states there are multiple nuisance alarms due to aircraft equipped with ADS-B. FLM would like some type of a software upgrade or an equipment upgrade to stop the spurious alerts.
