Abstract
A two-piece electronic siren apparatus including an integrated handheld microphone and control handle and a receiver/amplifier box is provided. The microphone and control handle permits handheld control of emergency light functions, siren functions, and auxiliary functions, as well as allowing a user to talk through a speaker. 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.
