The integrated receiver/amplifier box includes both a siren board and a relay board. The siren board includes a microprocessor capable of generating siren tones and of controlling, among other things, a power amplifier located on the siren board, and auxiliary devices and functions. Additionally, the microprocessor controls two default modes of operation of the siren and/or light circuitry.
