Operations
The modular UV controller contains a card cage with ten plug-in cards consisting of the
following:
• One controller card slot (UV+)
• One optional accessory slot (UVARM)
• Eight amplifier slots (UV400)
You can vary the number of amplifier cards from one for a 400-watt system up to a
maximum of eight for a 3200-watt system. All siren control, audio generation, and
remote communication functions are handled by the UV+ controller card. The backplane
motherboard contains connectors and terminal blocks for interconnection of the other
system components. Power for the UV Controller and siren is supplied by two or four
deep cycle marine batteries. AC and solar battery charger options are available.
