Burglar Alarm System Permit Requirements in Missouri

Missouri has unique requirements for alarm systems that differ from its general low voltage exemptions. While most low voltage work is exempt from licensing, electronic security companies have specific statewide requirements. Here's what contractors need to know about burglar alarm installation in Missouri.

State Licensing Requirements

Electronic Security Company License

Missouri requires a statewide license for businesses that install, maintain, or repair:

• Mechanical or electrical devices designed to emit an audible alarm if activated
• Devices that transmit a signal or message when activated
• Systems used to detect unauthorized entry into a building
• Systems that alert persons of an occurrence or medical emergency

This requirement applies to Contract Security Companies and Electronic Security Companies operating in Missouri.

Electrical Work Exemption

Separately, under Missouri Revised Statutes Section 324.915, the following is exempt from electrical contractor licensing:

• Installation, maintenance, and repair of fire alarm, intrusion alarm, or other limited energy signaling systems of 48 volts to ground or less

This means the physical installation work doesn't require an electrical license, but operating as an alarm company does require the security company license.

Local Alarm Registration

Many Missouri municipalities require alarm system registration:

St. Louis

St. Louis requires alarm registration through the Metropolitan Police Department. Property owners must register alarm systems before monitoring begins. The city has false alarm ordinances with escalating fees for repeated false dispatches.
