COMMUNICATION & SECURITY SOLUTIONS

Provide LED Strobe / Beacon

Visual Indication of Line Status

Features

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 can
not 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.

The 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.) Four 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).

The BLK-4 is designed for indoor applications. The BLK-

4-EWP is equipped with Enhanced Weather Protection
(EWP) for outdoor installations where the unit is exposed
to precipitation or condensation. For more information,
see DOD# 859.

The kit includes: (1) control module, (1) SL-2/SL-2-EWP
blue LED strobe light, (1) 12V DC power adapter, (16) gel­filled butt connectors and (1) single gang weatherproof
mounting box with gaskets and hardware.

• BLK-4-EWP’s control module and strobe light come
with Enhanced Weather Protection (EWP), EWP prod­ucts are designed to meet IP66 Ingress Protection
Rating, see DOD# 859

triggered from a contact closure

• One set of (NO) normally open and (NC) normally
closed relay contacts provided

• Selectable ring cadence mode (strobe light will remain
flashing between rings)

• Switched 12V DC output (follows relay activation for
powering strobe lights, cameras, etc.)

• On/off switches for ring detection and off-hook/loop
detection

A. Installing the Strobe Light Using the Included Weatherproof Box

* Note: The gel-filled (water tight) butt connectors are designed for insulation displacement. Do not strip wires
prior to terminating.
** Important: First fully tighten the nipple into the faceplate. Next add the (2) nylon spacers, then fasten the strobe
mounting ring.
*** Note: For outdoor applications, orient the blue strobe light with the screws at the top and bottom. Use a bead
of silicone to fill any gaps or spaces to prevent water from entering the strobe light.
