The BLK-4 provides high visibility indication of analog line status through a high powered 360º LED strobe and/or beacon visual indicator. The BLK-4 is the ideal solution for the hearing impaired and can be used equally well in loud warehouses or factories, where ringing phones cannot be heard. Alternatively, the BLK-4 can be used to add emergency notification to pre-existing emergency phones by turning on the strobe light when the emergency phone is in use.
