How do the short circuit, high voltage and reverse polarity protection systems work?
These systems are all incorporated into the circuit board to protect the amplifier from damage. The short circuit protection system protects the amplifier from a shorted or blown speaker. It senses when a short occurs in a speaker and blows the fuse to keep the amplifier components from overloading. The high voltage protection system protects the speaker from the amplifier when spikes in input voltage occur. The high voltage sensors detect when the input level rises above 16 volts and kills the sirens output. The siren automatically resets when voltage levels drop back down to normal levels. The reverse polarity protection system protects the amplifier by blowing the fuse if the power input connections are improperly connected. For example, if the positive wire is attached to the negative connector, the fuse will blow.
