{"product_id":"viking-blk-4","title":"Viking BLK-4","description":"\u003cp\u003eThe BLK-4 provides high visibility indication of analog line status through a high powered 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.\u003c\/p\u003e\n\u003cp\u003eThe included 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.).\u003c\/p\u003e\n\u003cp\u003eFour DIP switches are provided for turning ring detection on or off, off-hook \/ loop detection on or off, 12VDC or dry relay contact output, 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 strobe can be interfaced to flash on ringing, off-hook or a combination of ringing and off-hook (line in-use).\u003c\/p\u003e\n\u003cp\u003eFor outdoor installations where the unit is exposed to precipitation or condensation, use model BLK-4-EWP.\u003c\/p\u003e\n\u003cp\u003eThe BLK-4 includes: (1) control module, (1) SL-2 blue LED strobe light, (1) 12VDC power adapter, (16) gel-filled butt connectors and (1) single gang weatherproof mounting box with gaskets and hardware.\u003c\/p\u003e\n\u003ch3\u003e\u003cu\u003eCore Features:\u003c\/u\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDurable polycarbonate lens\u003c\/li\u003e\n\u003cli\u003eHigh-output long life LED technology\u003c\/li\u003e\n\u003cli\u003eFour programmable flash patterns:\n\u003cul\u003e\n\u003cli\u003eSingle Flash\u003c\/li\u003e\n\u003cli\u003eDouble Flash\u003c\/li\u003e\n\u003cli\u003eQuad Flash\u003c\/li\u003e\n\u003cli\u003eFlicker Flash\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e6 programmable beacon and strobe brightness settings\u003c\/li\u003e\n\u003cli\u003eImmune to shock and vibration\u003c\/li\u003e\n\u003cli\u003eFlush mount or surface mount with weatherproof single gang box (included)\u003c\/li\u003e\n\u003cli\u003e0.75″ knockouts for connecting conduit, etc.\u003c\/li\u003e\n\u003cli\u003eStrobe and control module may be installed separately\u003c\/li\u003e\n\u003cli\u003eCan be configured to signal: ringing, off-hook, a combination of both ringing and\u003cbr\u003e\noff-hook (line in-use), or triggered from a contact closure\u003c\/li\u003e\n\u003cli\u003eSPDT relay contacts provided\u003c\/li\u003e\n\u003cli\u003eSelectable ring cadence mode: strobe light will remain flashing between rings\u003c\/li\u003e\n\u003cli\u003eSwitched 12VDC output: follows relay activation for powering strobe lights, cameras, etc.\u003c\/li\u003e\n\u003cli\u003eDisable input, ideal for use with two-button emergency phones like Viking’s E-1600-20A (DOD 215),\u003cbr\u003e\nwill not activate strobe light on “Info” calls\u003c\/li\u003e\n\u003cli\u003eAdditional lens covers available separately:\n\u003cul\u003e\n\u003cli\u003eClear\u003c\/li\u003e\n\u003cli\u003eAmber\u003c\/li\u003e\n\u003cli\u003eBlue\u003c\/li\u003e\n\u003cli\u003eRed\u003c\/li\u003e\n\u003cli\u003eGreen\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Viking","offers":[{"title":"Default Title","offer_id":46237922001067,"sku":"VIK-BLK-4","price":228.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/8939\/3579\/files\/BLK-4.jpg?v=1771970395","url":"https:\/\/primebusinessphone.com\/products\/viking-blk-4","provider":"PrimeBusiness Phone","version":"1.0","type":"link"}
