Blue Light Strobe Kit, compatible with any emergency telephone or analog phone. Kit includes 4in diameter waterproof strobe, hardware, control module and 12V power supply. The BLK-3-EWP provides high visibility indication of analog line status through a high powered one million candle power strobe light. The BLK-3-EWP is the ideal solution for the hearing impaired and can be used equally well in loud warehouses or factories, where ringing phones can not be heard. Alternatively, the BLK-3- 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, see DOD# 409 for more information. The BLK-3-EWP is equipped with Enhanced Weather Protection (EWP) for outdoor installations where the unit is exposed to precipitation or condensation. EWP products feature foam rubber gaskets and boots, sealed connections, gel-filled butt connectors, as well as urethane or thermal plastic potted circuit boards with internally sealed, field-adjustable trim pots and DIP switches for easy on-site programming. For more information, see DOD# 859. 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.
