Ecolink firefighter alarm only tells temp, battery and tamper, never recognizes smoke alarms going off

Got an ecolink firefighter which pairs properly using the ecolink DH, and reports to me if cover is removed, as well as temp and battery, but will not notify me when smoke alarm goes off no matter how close I put it to the smoke alarm or how many times I try. Is it defective or am I doing something wrong?
