DSPK4 User Station Introduction | en 9
Bosch Security Systems, LLC Technical Manual 2023-03 | V01 | F.01U.409.148
2 Introduction
The DSPK4 (Digital Speaker Station) is an IP-based version of its wired analog speaker station
predecessor, with several key enhancements, such as high quality digital audio and the use of
standard Ethernet, making it compatible and versatile to fit into any environment.
Building on the versatility, DSPK4 comes in three different variants: a desktop version, a wall
mount version, and a flush mount version. There is a model for every situation. The flush
mount version comes with 4-pin female, 4-pin male, or 5-pin female front panel headset XLR
connector. RTS offers a purchasable 4-gang electrical box for the flush mount model
installation. The wall mount and desktop versions have all three XLR connectors.
Power the DSPK4 via an external AC/DC power adapter, a DC +24 V terminal block, or by
PoE+ / PoE++ (Power over Ethernet). In addition, you can have peace of mind when powering
the DSPK4 with Local DC power because PoE+ / PoE++ is ready to take over as a redundant
power supply with no interruptions if the unexpected happens.
The DSPK4 has a full-color TFT display and an icon-based menu interface, which allows for
local configuration of essential customer preferences.
Features
– Supports power redundancy from an external DC power supply or the Local +24V
terminal block to PoE+ / PoE++
– Supports connections to an OMNEO Main Station (Digital Party Line) or an OMNEO
capable matrix (ADAM or ADAM M with OMI installed or ODIN).
– Features a high-resolution TFT display, allowing user setup and configuration using an
icon-based GUI.
– Multiple DSPK4 variants: Desktop and Wall Mount devices with 4-pin and 5-pin headset
connectors and a Flush Mount device with 4-pin male, 4-pin female or 5-pin female
connector options.
– Supports Bluetooth audio connectivity via Bluetooth enabled USB dongles and phone
connectivity.

5 Mounting instructions
5.1 Mount the DSPK4-W wall mount
i
Notice!
We recommend that this device not be mounted in a high traffic area where it could be
accidently dismantled. Always observe local codes and requirements.
Before mounting the unit:
– It may be necessary to predrill the holes or use screw anchors, depending on the type of
mounting surface.
– The unit comes with three wood screws. If you need to use different screws due to a
different mounting surface, be sure to adhere to the following guidelines:
– Screw diameter: M5
– Screw head diameter: no more than 10mm across
– Screw head height: no more than 3.5mm tall
– The screw spacing is not consistent with standard residential stud spacing. You may need
to use appropriate wall anchors if mounting the DSPK4 on a gypsum wall.
!
Caution!
Proper wall mounting
To reduce the risk of injury to yourself or damage to the device:
- Follow all instructions provided.
- Ensure the wall structure/materials will support the weight of the device.
- Use the recommended hardware for your device based on the wall structure/materials.
- Additional reinforcement may be required depending on the wall structure/materials the
device will be installed and local codes and standards.
To mount the unit on the wall, do the following:
1. Using the screw-hole template provided in the box and a pencil, mark the three screw
hole locations on the wall.
2. Using a screwdriver, drive screws into the predefined holes.

3. Align the bottom of the unit over the screws, allowing the screw heads to slide into the
largest part of the keyhole opening.

4. Using suitable force, slide the unit downward, ensuring it locks into place.
If the unit does not lock in place, remove it completely from the wall and retry
IMPORTANT:
It is necessary for all screws to protrude from the wall at approximately the same height. The
height should be 4-6mm from the underside of the screw head to the wall.
– If the screw is inserted too far, the unit cannot latch in place.
– If the screw is not inserted far enough, the unit is not locked in place properly and can
potentially fall off the wall.
5.2 Mount the DSPK4-F flush mount
5.2.1 Console mounting
If you choose to console mount your unit, you can power the unit using PoE, External DC
Power Supply, or DC Terminal Block. For more information, see Power, page 21 .
i
Notice!
If using External DC Power Supply or DC Terminal Block, PoE can act as a failover option. This
means if DC Power fails, the unit automatically switches to PoE.
To console mount the unit, do the following:
1. Use the console mounting cutout guide found in the box to cut a hole in the surface to
which you are installing the unit and drill the clearance holes.
2. Place the unit in the console cutout.
3. On the rear panel of the unit, thread the screws through the clearance holes from the
back of the console into the rear panel of the unit.

Notice!
Front Panel Damage/Dimpling
The screws needs to protrude past the console-mounting surface at a minimum of 10 mm, but
no more than 14 mm. Any more than 14mm can cause dimpling/damage to the front cover of
the unit.
10-14 mm

5.2.2 Standard 4-gang electrical box mounting
i
Notice!
We recommend using a metal 4-gang electrical box, not a plastic or other material electrical
box.
RTS offers a purchasable 4-gang electrical box for flush-mount model installation.
To mount in a standard 4-gang electrical box, do the following:
1. Using a flat head screwdriver, gently pry the four rubber plugs from the front panel.
2. Remove the knockouts from the bottom of the electrical box to allow for wire routing.
You may not use every knock out. It depends on the connections to the device.
i
Notice!
You cannot power the flush mount unit with the External DC power supply when using it in
combination with an electrical box. The connector protrudes too far.
We recommend using PoE+/++ to power the unit.
3. Thread the cables through the knockouts on the electrical box.

DSPK4 User Station Mounting instructions | en 19
Bosch Security Systems, LLC Technical Manual 2023-03 | V01 | F.01U.409.148
4. Connect the cables to the unit.
5. Tip the unit forward slightly so the cables clear the metal lip of the electrical box while
inserting it into the electrical box.
