Fire alarm and detection
Smoke and heat detectors, pull stations and the panel that decides when to sound the alarm.
● Commercial security
Fire alarm panels, smoke and heat detection, notification devices and 24/7 monitoring, installed and serviced by a local team. From new buildings and renovations to inherited systems that need attention.

Commercial fire protection is the set of systems that detect a fire, warn people and get help on the way. The core is the fire alarm system: it detects smoke, heat or sprinkler flow, sounds horns and strobes to get people out, and signals a monitoring center so the fire department is called. It also includes the inspection and service that keep the system working and ready for the fire marshal.
Turner Security installs, monitors, inspects and services commercial fire alarm systems for businesses in Middle Tennessee and the Chattanooga area, working with established fire alarm panel manufacturers and a UL-listed central station for monitoring.
Commercial fire protection is usually a combination of systems: sprinklers, special suppression such as kitchen hood systems, portable extinguishers, and the alarm and monitoring side that ties them together. Which ones a building needs depends on its use, size and occupancy, and on what the local fire marshal requires. The cards below cover the alarm, detection and monitoring side.
Smoke and heat detectors, pull stations and the panel that decides when to sound the alarm.
Horns, strobes and speakers that get people out, including voice evacuation in some buildings.
Flow and tamper switches that report sprinkler activity or a closed valve to the panel and monitoring center.
Alarm, supervisory and trouble signals sent to a monitoring center that contacts the fire department and you.
Duct detectors on HVAC systems and detection for kitchens, server rooms or other special areas.
Scheduled testing and repair that keep the system ready and documented for the fire marshal.
Turner Security has served businesses since 1976 from offices in Smyrna and Chattanooga. Because we also handle intrusion alarms, cameras and access control, your fire and security systems can be serviced by one team instead of several vendors.
We don't require long-term agreements. Many trouble signals can be diagnosed remotely by our help desk, and we can often schedule a service visit the same day you call.
Every building is different. We start with the facility, how it is used and the system that is already there.
New fire alarm panels, detectors, pull stations and notification devices for new construction, buildouts and replacements.
Alarm, supervisory and trouble signals are sent to a UL-listed central station that dispatches the fire department and notifies your contacts.
Scheduled inspection and testing of devices and panels, with documentation you can keep on file.
Troubleshooting trouble signals, replacing failed devices and fixing the problems that cause false alarms.
Adding or moving devices when you remodel, expand or change how a space is used.
Review of older panels and devices, with a clear answer on what can be kept, what needs repair and what should be replaced.
Fire alarms protect people first, and they are also what insurers and fire marshals look at. A system with ignored trouble lights, missed inspections or old devices puts both at risk.
Working with one local company for fire, security and cameras means fewer vendors, one service call and a team that already knows your building.

Clear scope before any work starts.
We look at the building, how it is used and the condition of any existing fire alarm system.
We confirm what the project needs and give you a written proposal with a clear price.
Our technicians install, upgrade or repair the system and test every device.
We connect monitoring and keep the system inspected and serviced going forward.
A conventional panel groups devices into zones, so it can tell you which area has a problem but not which detector. An addressable panel identifies each device individually, which makes troubleshooting faster and is common in larger or more complex buildings. The right choice depends on the building and the code requirements for it.
We install and service panels and devices from manufacturers including Fire-Lite, Silent Knight, Honeywell, Potter and System Sensor, and we can often take over service on a system another company installed.
Commercial fire alarm systems are generally inspected and tested on a schedule set by NFPA 72 and adopted by your local fire code official, with most devices checked at least once a year. The exact requirements for your building come from the authority having jurisdiction, so we plan inspections around what your fire marshal expects and keep the records ready.
Cost depends on the size of the building, the number of devices, whether there is a sprinkler system to monitor, and whether existing wiring and devices can be reused. We review the facility and give you a written proposal with a clear price.
Yes. Fire alarm signals are sent to a UL-listed central station 24/7, which dispatches the fire department and notifies your contacts.
Most commercial fire alarm systems need inspection and testing at least once a year, and some devices more often, depending on fire code and your local fire marshal. We can help you set up a schedule that fits your building.
Often, yes. We review the existing panel and devices, fix what can be repaired and tell you clearly if any part of the system should be replaced.
Trouble signals usually point to a failed device, a wiring problem, a low backup battery or a lost communication path to the monitoring center. Call us and we will troubleshoot it, often starting remotely.
Yes. Turner Security installs and services fire alarms, intrusion alarms, cameras and access control, so one team knows your whole building.
The main types are fire sprinkler systems, special suppression such as kitchen hood systems, portable extinguishers, and the fire alarm side: detection, occupant notification, sprinkler monitoring, central station monitoring, special detection such as duct detectors, and the inspection and testing that keeps it all working. A building's use and the local fire code decide which ones are required.
Choose a company that installs, monitors, inspects and services fire alarms, so one team is responsible for the whole system. Turner Security does all four for businesses in Nashville, Middle Tennessee and the Chattanooga area.
Turner Security provides fire alarm monitoring for businesses across Middle Tennessee and the Chattanooga region. Alarm, supervisory and trouble signals go to a monitoring center that contacts the fire department and your call list.
A conventional panel reports problems by zone, while an addressable panel identifies the exact device. Addressable systems make troubleshooting faster and are common in larger buildings.
