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.

Auxiliary Relay Contact Output
120V AC
DIP switch 2 is used for switching between different ring detection modes. In the OFF position, the relay and
switched 12VDC output will activate only while ring voltage is present and will turn off between rings. In the ON
position, the relay and switched 12VDC output will remain on for up to 5.75 seconds after the ringing has stopped.
This allows the relay and 12VDC (flashing strobe light) to remain on between rings of a standard ring cadence.
Note: To use the Ring Cadence Mode, ring detection MUST be enabled (DIP switch 1 - ON).
C. Ring Cadence Mode
With DIP switch 4 OFF, normally open and normally closed dry relay contacts are available on the orange, purple
and yellow wires. The contacts are rated at .5A @ 125VAC/1A @ 30VDC. If contacts are driving an inductive
load, place a suppression device at the load to snub high voltage spikes.
With DIP switch 4 ON, wet/switched +12VDC (100mA maximum) will be output on the yellow wire and “-” (GND)
on the black wire.
D. Auxiliary Relay Contacts
The switched 12V DC output is a low current, 12-15VDC output that is turned on only while the trigger input is
closed or ring/loop detect relay is activated. This switched power output is ideal for triggering the included strobe
light or providing 12-15V DC power to any device that draws less than 400mAmps. The positive side is available
on the green wire, and the negative side is on the black wire. Once all the line and load connections have been
made, plug in the 115 V AC wall adapter, and replace the cover.
E. Switched 12V DC Output
By connecting the Disable/Info Switch input of the BLK-4 control module to the “Info” switch of Viking’s E-160020A, E-1600-20A-EWP, E-1600-52A or E-1600-52A-EWP Emergency Phone, any outbound call initiated from
the “Info” button will not activate the strobe light. This way, only the “Help/Emergency” outbound calls will activate
the relay. Cut one of the “Info” switch wires in half and connect each end to the blue wires on the BLK-4 control
module as shown in the diagram at the right. Note: This Disable input is NOT polarity sensitive. The “Disable”
input can be connected to a switch for remotely disabling/turning off the device (strobe light, camera, etc.) controlled by the BLK-4 control modile. For more information, see DOD# 866.
F. Disable Feature
The trigger input is available on the two white wires. The Strobe Light, Auxiliary relay contact and the switched 12
VDC output will be activated for the duration of the contact closure across the two white wires.

B. Programming Desired Features (after accessing Programming Mode above)
Select the Feature: Momentarily touch the Green (Control) wire to the Black (-) wire 1 to 10 times to select which
feature to program (see Programming Features List, section C). The strobe should momentarily flash each time
the Green (Control) wire has touched the Black (-) wire.
Features 1-3 & 6-10: After selecting Programming Features 1-3 or 6-10, wait 3 seconds and the strobe should
flash 2 times indicating that feature has been programmed. You can now exit programming or move on to programming the Beacon or Strobe brightness settings.
Setting Strobe Brightness (factory set to 6/Brightest): After selecting Programming Feature 4 (Strobe Brightness), wait 3 seconds and the strobe should begin flashing in the preprogrammed flash pattern. Touch and hold
the Green (Control) wire to the Black (-) wire. The SL-2 will begin flashing the strobe cycling through 6 different
brightness settings from lowest to highest. When the SL-2 flashes at the desired brightness level immediately remove the Green wire from the Black. The SL-2 should flash twice indicating the selected brightness level has
been set.
Setting Beacon Brightness (Factory set to 6/Brightest): After selecting Programming Feature 5 (Beacon Brightness), wait 3 seconds and the beacon will light at its preprogrammed beacon brightness setting. Touch and hold
the Green (Control) wire to the Black (-) wire. The SL-2 will begin stepping through 6 different beacon brightness
settings from lowest to highest. When the SL-2 lights at the desired beacon brightness level immediately remove
the Green wire from the Black. The SL-2 should flash twice indicating the selected brightness level has been set.
Exiting Programming: To exit programming simply wait 20 seconds from the last programming command and
the unit will flash 3 times. This indicates the SL-2 has exited the programming mode and is now in the Run mode.
Note: To eliminate waiting 20 seconds, you can also exit programming after the last programming command by
touching and holding the Green (Control) wire to the Black (-) for 3 seconds. The strobe will flash 3 times indicating
the unit has exited the programming mode and is now in the Run mode.
A. Accessing the Programming Mode
(Optional, the SL-2 is factory programmed to the Beacon/Strobe Mode and brightest Beacon/Strobe settings).
Step 1. Apply 10-15 VDC power to the Red (+) and Black (-) wires.
Step 2.
Touch and hold the Green (Control) wire to the Black (-) wire for 3 seconds. The strobe should flash
twice. You are now in Programming mode. Note: Once in the programming mode, if a programming
command has not been entered for 20 seconds the strobe will flash 3 times indicating the unit has
exited programming and returned to the Run Mode.
Programming the SL-2 Strobe / Beacon
The SL-2 can be user programmed as a Beacon only, Strobe only or Beacon/Strobe. The brightness setting can be
programmed separately for the Strobe or Beacon and one of 4 different Flash Patterns can be programmed for the
Strobe (See Strobe Flash Patterns, section D). Note: The SL-2 is factory default programmed as a steady on beacon
with a single flash strobe when activated. The beacon and strobe are set to their brightest settings. All programming
should be done prior to connecting to the BLK-4 control module.

Operation
When the control module detects an incoming ring signal, it activates a set of normally open or normally closed
contacts and turns on the 12VDC output for activating the provided strobe light. With the Ring Cadence mode off
(DIP switch 2 OFF), the relay will activate and the strobe light will flash only during ringing. With the Ring Cadence
mode ON (DIP switch 2 ON), the relay will remain activated and the strobe light will remain flashing between rings.
A. Ring Indication (DIP Switch 1 ON)
When the control module detects an off-hook condition (loop current) on the brown and gray wires, it activates a
set of normally open or normally closed contacts and turns on the 12VDC output for activating the provided strobe
light. The relay contacts will remain activated and the blue strobe light will flash during the off-hook condition and
will stop flashing approximately 3 seconds after the phone/terminal device on the brown and gray wires is back
on-hook.
B. Off-Hook Indication (DIP Switch 3 ON)
