Frequently Asked Questions - SBS-400 Valcom

What voltage does the Valcom SBS-400 require?

The SBS-400 typically operates on 24 VDC supplied by a Valcom power source or via Power over Ethernet (PoE) if using an appropriate adapter.

How do I connect the SBS-400 to my paging system?

Use the included RJ-45 cable or screw terminals. For standard Valcom systems, connect to a V-1030A or similar control panel following the wiring diagram in the manual.

Can the SBS-400 be used outdoors?

No, it is designed for indoor use only. Exposure to moisture or extreme temperatures may damage the unit.

What is the maximum wiring distance?

How do I adjust the volume?

Locate the volume potentiometer on the side of the unit. Turn clockwise to increase, counterclockwise to decrease. A small screwdriver may be required.

Why is there no sound from the speaker?

Check power supply connections, ensure the unit is receiving 24 VDC, and verify that the audio source (e.g., paging system) is active. Also inspect the driver for damage.

Yes, up to four units can be daisy-chained using the RJ-45 pass-through. Ensure total power draw does not exceed the power supply rating.
