INSTALLATION
Mounting
The VP-4124 and VP-4124-E are designed for
wall
mounting only
. The unit should be mounted within 7
feet of an AC receptacle.
Screw mounting plate to wall and position power
supply on mounting plate via the mounting slots.
See pages 5 and 6 for mounting instructions.
Connections
•
Connections to Valcom page control units are
shown in Figure 1.
•
When using the VP-4124 or VP-4124-E as a
-24VDC power supply with Valcom page
equipment, a strap may be added from the local
ground terminal to both of the "+" outputs to
provide an AC ground reference.
•
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 3 seconds delay.
NOTE: Each -24VDC screw terminal is fused by a 2
Amp polyswitch automatic. Therefore, when
connecting equipment to this power supply, the load
should be distributed between the (2) 2 Amp output
terminals (within 1.5 Amps) and each load should
not exceed 2 Amps.
