Abstract:
Apparatus for controlling visible and audible warning signals, particularly signals from light bars, traffic director lighting, and siren and public address outputs for police and emergency vehicle applications, is provided in a single unit. Mounted in a chassis of the unit in layered relationship are a siren board and a relay board. The siren board contains amplifier and associated circuitry for generating and amplifying siren signals, and for providing microphone signals and signals from a 2-way radio of the vehicle, to a speaker which projects these audible signals for warning of and controlling emergency conditions. The relay board contains circuitry for switching power from the vehicle battery to the traffic director lighting and warning lighting (as may be provided by light bars) mounted on or in the vehicle. A microcontroller switches the lighting to the selected lighting units via relays on the board. A controller utilizing buttons providing a keypad, rotary and slide switches, is mounted on the chassis at one end thereof to provide manual access to the police or other emergency personnel for controlling the lighting and the siren, as well as public announce and radio audible signals.
