These instructions provide the specifications,
installation and maintenance information for the
VP-6124 and VP-6124-E, 24Volt Power Supplies.
SPECIFICATIONS
The VP-6124 and VP-6124-E are fully regulated
24VDC, 6 Amp switching power supplies. The
primary is protected by a 4 Amp slo-blow fuse and
the 2 Amp outputs by auto resetting fuses. The
outputs are floating with respect to ground. The
regulator will maintain 24 Volts +/-2% over the
rated range of input voltages and output loads. A
greater than 6 Amp load on power up will cause the
power supply to current limit. Short circuit
protection is provided. Over voltage is provided to
limit the output voltage to approximately 28 Volts
should a failure occur within the power supply.
Outputs may be paralleled but not series connected.
Applications
The VP-6124/VP-6124-E are designed to be used
with:
• All Valcom page control units
• Valcom one-way amplified speaker assemblies
• Any application where 24VDC filtered talk
battery is required

FCC
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference
received, including interference that may cause
undesired operation.
NOTE: This equipment has been tested and found
to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference in a
residential installation. This equipment
generates, uses and can radiate radio frequency
energy and if not installed and used in accordance
with the instructions, may cause harmful
interference to radio communications. However,
there is no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interference to
radio or television reception, which can be
determined by turning the equipment off and on,
the user is encouraged to try to correct the
interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the
equipment and receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced
radio/TV technician for help.
INSTALLATION
Mounting
The VP-6124 and VP-6124-E are designed for wall
mounting only. The unit should be mounted within
seven feet of an AC receptacle.
• Screw mounting plate to wall and position power
supply on mounting plate via the mounting slots.
• See page 4 for mounting instructions.
Connections
• Connections to Valcom page control units are
shown in Figure 1.
• When using the VP-6124 or VP-6124-E with
Valcom page equipment, a strap may be added
from the local ground terminal to either of the
"+" outputs.
• When installing Valcom one-way amplified
horns, connect the white and black wires of the
horn to the power supply "-" and "+" terminals
respectively.
• When installing Valcom one-way speakers,
connect the "-24VDC" and "GND" terminals of
the speaker to the "-" and "+" terminals
respectively.
• Plug power supply into wall outlet.
• Power supply activates after a 3 seconds delay.
• Use CAT-5 wire.
NOTE: Each 24VDC screw terminal is fused by a
2 Amp polyswitch automatic type fuse. Therefore,
when connecting equipment to this power supply,
the load should be distributed between the (3) 2
Amp output terminals and each load should not
exceed 2 Amps.

Mounting
Use Steps 1 through 3 and Figures 2 and 3 to mount the power supply on a wall or other surface capable of
supporting the weight of the supply (approximately 5 pounds). Carefully unpack the power supply and inspect for
shipping damage.
Select a location for installation of the power supply in a clean, dry, vibration-free area with moderate temperature
within six feet of an approved AC outlet.
1. Using the mounting bracket (see Figure 2) as a template, mark the two slotted holes on the surface of the wall.
2. Using mounting hardware capable of supporting approximately 5 pounds, mount the bracket to the wall ensuring
that the mounting holes are oriented as shown in Figure 2.
