Valcom Power Units

Every Valcom product is marked with either a positive, negative or neutral power unit.

Simply add up the negative power units and then purchase a power supply with a greater value than the total power consumption of the system.  If you have extra power units you can add speakers to the system at a later date, extra power is OK lower power will cause a performance problem on your paging system.

One Valcom power unit = 50 mA, -24 Vdc
