The AC62 also includes a Fire Alarm Interface (FAI). The FAI on the AC62 can power down door locks when a signal from a Fire Alarm Control Panel (FACP) is received. In other words, the AC62 will de-energize powered locks in case of the fire emergency to unlock fail safe doors. The most common use case is to remove power from maglocks when a fire alarm occurs, allowing for faster egress and firefighter access.
