Ohio low voltage license: Ohio expressly excludes work limited to fire alarm, burglar alarm, cabling, tele-data sound, communication, landscape lighting and irrigation systems using less than 50 volts from the OCILB electrical-contractor license. That exemption does not eliminate State Fire Marshal certificates for fire-protection equipment, municipal contractor rules or electrical and fire permits.
