The BLK-4 from Viking is a phone strobe light designed that provides high visibility indication of analog line status through a high powered 360º LED strobe and/or beacon visual indicator. The BLK-4 is perfect for the hearing impaired and can be used equally well in loud warehouses or factories, where ringing phones cannot be heard. The BLK-4 Strobe light can also be used to add emergency notification to pre-existing emergency phones by turning on the strobe light when the emergency phone is in use.
Great for loud areas such as Repair shops, manufacturing, industrial, garages, and more.
