phone: 225-772-7809 ## FAQ **How do I check that a fire alarm company in Houston is licensed?** Search the company name or registration number in the Texas State Fire Marshal's Office public lookup (https://appscenter.tdi.texas.gov/reports/p/sfmo). Every company listed here shows its registration numbers and expiration dates, re-checked against state records on each data refresh. **What license does a fire alarm company need in Texas?** Companies doing this work must hold a Texas SFMO Fire Alarm Certificate of Registration (ACR). Texas requires a State Fire Marshal's Office certificate of registration for each type of work: fire alarm (ACR), fire extinguisher (ECR) and fire sprinkler (SCR). Individual technicians must also hold SFMO licenses. **Does a company need to be located in Houston to work there?** No. Texas registrations are statewide, so companies based elsewhere in Harris County or across Texas can work in Houston. Confirm the service area with the company. _Source: Texas Department of Insurance, State Fire Marshal's Office licensee records (https://appscenter.tdi.texas.gov/reports/p/sfmo), retrieved October 24, 2026.
