The Viking High Powered Telephone Strobe Light BLK-4-EWP delivers a highly visible blue flashing light when your phone is ringing through a high powered one million candle power strobe light. The Telephone Flasher 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-EWP 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. The included LDB-3 control module has a disable input which is ideal for two-button emergency phones, such as Viking’s E-1600-20A, allowing "Info" button calls to be placed without activating the relay (turning on the emergency strobe light, camera, etc.) Three DIP switches are provided for turning ring detection on or off, off-hook/loop detection on or off and for selecting a ring cadence mode which allows the relay to follow ringing or to remain activated during the off time of standard ring cadence. The control module can be installed on any standard telephone line or analog PABX/KSU station. The 1 million candle power strobe can be interfaced to flash on ringing, off-hook or a combination of ringing and off-hook (line in-use). The LDB-3 ring/loop detect control module is also available separately. The kit includes: (1) LDB-3 control module, (1) blue strobe light, (1) 12V DC power adapter, (13) gel filled butt connectors and (1) single gang weatherproof mounting box with gaskets and hardware.
