Welcome to Signal 21

Commercial and Residential Security Systems

Signal 21 Security Systems, Inc., was established in 1981, and is located just east of Town Hall in the historic downtown Orange City, FL.  We are your resource for commercial and residential burglar alarm and fire alarm systems for Volusia, Lake and Seminole Counties.

We install new security systems, as well as inspect existing security systems for both commercial and residential properties.

All of our systems are designed individually based on your unique needs.  We don’t promote a fixed package of components like many mass marketing Alarm Companies. We realize that cost and level of protection are both important.

“Signal 21 only installs non-proprietary equipment and doesn’t require long-term contracts.”

We offer 24-hour U.L. listed monitoring for burglar alarm systems and fire alarm systems, annual fire alarm system inspections as required for most commercial fire alarm systems, security system repair and maintenance for most burglar alarm and fire alarm systems, as well as stock batteries for most burglar alarm systems.

All Signal 21 installation, service and inspection work is performed by local Signal 21 employees, compared to most mass marketing companies which use subcontractors for their installation and service work.

Signal 21 only installs non-proprietary equipment.   Most mass marketing Alarm Companies install proprietary equipment, which locks you into that single company for all your future alarm needs.  You can’t get service or monitoring from any other company without purchasing new equipment.  This is very important to consider from a consumer viewpoint.

Signal 21 does not require that you sign a long term monitoring contract.  We offer high quality , low cost 24 hour U.L. Monitoring service for burglar alarms with low monthly fees.  If monitoring service is not requested, no monthly fees will be necessary.

Please feel free to call with questions about system design or any of our services.
