Summary
Columbus lets you install a theft alarm on your vehicle, but City Code § 2137.19 requires it be wired so it can't double as your horn or ordinary warning signal.
No motor vehicle shall be equipped with, nor shall any person use upon a vehicle, any siren, whistle, or bell. Any vehicle may be equipped with a theft alarm signal device which shall be so arranged that it cannot be used as an ordinary warning signal. Every emergency or public safety vehicle shall be equipped with a siren, whistle, or bell capable of emitting sound audible under normal conditions from a distance of not less than five hundred (500) feet and of a type approved by the Ohio Department of Public Safety. Such equipment shall not be used except when such vehicle is operated in response to an emergency call or is in the immediate pursuit of an actual or suspected violator of the law, in which case the driver of the emergency or public safety vehicle shall sound such equipment when it is necessary to warn pedestrians and other drivers of the approach thereof.

Full Breakdown
Under Columbus City Codes § 2137.19, no motor vehicle may carry a siren, whistle, or bell, but any vehicle may carry a theft alarm signal device: provided it's arranged so it can't function as an ordinary horn or warning signal. The rule sits in the vehicle-equipment chapter of the traffic code, not the noise code, so it governs installation, not decibel limits. A car alarm that goes off and disturbs neighbors can still trigger the city's separate community noise ordinance (Columbus City Codes § 2329.11), which treats a parked vehicle as a 'stationary sound source' subject to the same audibility limits as any other noise.
Violations & Fines
First offense is a minor misdemeanor; a repeat conviction within one year for this section or ORC § 4513.21 escalates to a fourth-degree, then third-degree, misdemeanor.
